How to Build a Complete Mobile App in 48 Hours Using AI (No Coding Required)

Last month, I challenged myself to build a fully functional budget tracking app in just 48 hours—without writing a single line of code. I’m not a developer. I’m a designer who’s dabbled in app concepts but never had the technical skills to bring them to life. But with AI tools transforming the app development landscape in 2025, I thought: why not give it a shot?

The result? A working mobile app with user authentication, database integration, and a polished interface that I submitted to both the App Store and Google Play. The entire process took exactly 47 hours and 32 minutes, and it cost me less than $100. If I can do this, anyone can

In this comprehensive guide, I’ll walk you through every step of the process, from initial research to publishing your app. You’ll discover the exact tools I used, the prompts that worked (and those that didn’t), and the shortcuts that saved hours of frustration

What You’ll Create

By following this tutorial, you’ll build a complete mobile application with :

• User authentication (sign up, login, password reset)
• Full CRUD functionality (Create, Read, Update, Delete)
• Cloud database integration
• Push notifications
• Professional UI/UX design
• Responsive layouts for all screen sizes
• Ready-to-publish app files for iOS and Android

The best part? You don’t need any coding experience. Just patience, creativity, and a willingness to learn new tools

Before we dive in, here are the tools we’ll be using :

1. FigJam AI – For brainstorming and user research (https://www.figma.com/figjam/)
2. Mobbin – For design inspiration and competitor analysis (https://mobbin.com/)
3. Figma with AI features – For UI design (https://www.figma.com/)
4. FlutterFlow – For building the actual app (https://flutterflow.io/)
5. Firebase – For backend and database (https://firebase.google.com/)
6. ChatGPT – For content generation and problem-solving (https://chat.openai.com/)

Total cost for this project: $0-30 for free tiers, $70-100 if you want premium features for faster development

Step 1: User Research with FigJam AI (4 Hours)

The foundation of any successful app is understanding your users. I spent the first four hours researching, planning, and defining exactly what my app would do

Brainstorming Your App Idea

Open FigJam and create a new file. The AI assistant in FigJam can help you generate mind maps automatically. Here’s what I did :

1. Started with a central node: “Budget Tracking App”
2. Asked FigJam AI: “Generate a mind map for essential features of a personal budget tracking app”
3. The AI generated branches for: Income tracking, Expense categories, Bill reminders, Savings goals, Data visualization, Export features

The AI suggestions were surprisingly comprehensive. It even suggested features I hadn’t considered, like recurring transaction templates and budget sharing for couples

Creating User Personas

Next, I used ChatGPT to create detailed user personas. My prompt :

Create 3 detailed user personas for a budget tracking app. Include :

– Demographics (age, occupation, income level)

– Pain points with current budget solutions

– Goals and motivations

– Tech proficiency level

– Key features they need most

The personas helped me prioritize features. For my 48-hour timeline, I focused on the must-haves that would serve all three persona types

Competitor Analysis with Mobbin

Mobbin is a goldmine for app design research. I searched for “budget tracking” and “finance apps” to see what’s already out there. The platform has thousands of app screenshots organized by screen type

I spent about 90 minutes analyzing :

• Onboarding flows (how apps introduce themselves to new users)
• Dashboard layouts (how financial data is displayed)
• Transaction entry forms (the quickest ways to log expenses)
• Navigation patterns (bottom tabs vs. hamburger menus

I took screenshots and organized them in a FigJam board, noting what worked well and what I wanted to improve upon

Defining Core Features

Based on my research, I narrowed down to these essential features for my 48-hour build :

Must-Have Features:

• User registration and login
• Add/edit/delete transactions
• Categorize expenses (food, transport, entertainment, etc.)
• View spending by category
• Monthly budget setting
• Simple dashboard with current month overview

Nice-to-Have (if time permits):

• Charts and graphs
• Recurring transactions
• Budget alerts
• Export to CSV

Deliverable: At the end of Step 1, I had a complete research document with user personas, competitive analysis, feature prioritization, and initial user flow diagrams. This foundation would guide every decision in the next 43 hours

Step 2: App Flow Design with AI (3 Hours)

With my research complete, I moved to mapping out the user journey. Every screen, every tap, every decision the user would make

Generating Flowcharts with FigJam AI

FigJam’s AI can create flowcharts automatically. I used this prompt :

Create a user flow diagram for a budget tracking app with these screens:

– Splash screen → Onboarding → Login/Signup → Dashboard → Add Transaction → Transaction List → Category View → Profile Settings

Show decision points and navigation paths

The AI generated a basic flow, which I then customized to match my specific needs. The automated flowchart saved me at least an hour of manual diagramming

Mapping Key User Journeys

I created separate flows for different user scenarios :

1. First-Time User Journey:
   • App launch → Onboarding slides → Sign up → Setup monthly budget → Add first transaction → View dashboard
2. Returning User Journey:
   • App launch → Login (biometric) → Dashboard → Quick actions
3. Transaction Entry Journey:
   • Dashboard → Tap “Add” → Select category → Enter amount → Add note (optional) → Save → See updated dashboard

These detailed flows helped me identify exactly how many screens I needed to design and build

Screen List Creation

By the end of this step, I had a comprehensive list of required screens:

• Splash screen (1)
• Onboarding screens (3 slides)
• Authentication (Login, Signup, Forgot Password) (3)
• Dashboard (1)
• Add Transaction (1)
• Transaction List (1)
• Transaction Detail/Edit (1)
• Categories Overview (1)
• Profile/Settings (1)

Total: 13 screens to design and build in the remaining time

Deliverable: Complete app flow diagram showing all screens, navigation paths, and user decision points. This became my blueprint for the design phase

Step 3: UI Design with Figma AI’s First Draft (8 Hours)

This was the most exciting part. Watching AI generate beautiful app screens in seconds felt like magic

Setting Up Your Figma Project

I created a new Figma file and set up frames for mobile screens :

• iPhone 14 Pro: 393 × 852px
• Android Standard: 360 × 800px

Having both platform sizes helped ensure responsive design from the start

Using Figma AI to Generate Screens

Figma’s AI features (accessed through plugins and Figma AI beta) can generate entire screens based on text descriptions. Here’s my process :

For the Dashboard screen, I used this prompt :

Create a modern budget tracking app dashboard with:

– Header showing current month and total balance

– Circular progress chart showing budget used vs remaining

– List of recent transactions (5 items) with icons, category names, and amounts

– Bottom navigation with Dashboard, Transactions, Categories, Profile icons

– Color scheme: Primary blue (#4A90E2), Secondary green (#50C878) for income, Red (#FF6B6B) for expenses

– Clean, minimal design with plenty of white space

– Card-based layout with soft shadows

The AI generated a screen that was 80% of what I envisioned. I spent the next 30 minutes customizing :

• Adjusting spacing and padding
• Refining the color palette
• Choosing better icons from the Iconify plugin
• Setting up a typography system (headers, body text, captions)

Creating a Design System

Instead of designing each screen from scratch, I built a design system first:

Colors:

• Primary: #4A90E2 (Trust-inspiring blue)
• Success: #50C878 (Income green)
• Error: #FF6B6B (Expense red)
• Background: #F7F9FC (Soft grey)
• Text Primary: #2C3E50
• Text Secondary: #95A5A6

Typography:

• Headers: Inter Bold, 24-32px
• Subheaders: Inter Semibold, 18-20px
• Body: Inter Regular, 14-16px
• Captions: Inter Regular, 12px

Components I Created:

• Button (primary, secondary, outline variants)
• Input fields (text, number, date, dropdown)
• Transaction card
• Category icon buttons
• Bottom navigation bar

AI helped here too. Figma AI can suggest component variants and auto-layout configurations. It saved hours of repetitive work

Designing All 13 Screens

With my design system in place, creating the remaining screens went much faster :

Hour 3-4: Authentication screens (Login, Signup, Forgot Password) Hour 5-6: Transaction screens (Add, List, Detail) Hour 7: Category and Profile screens Hour 8: Onboarding flow and final polish

For each screen, I used AI to generate the initial layout, then customized it to match my design system. The key was having clear, detailed prompts

Screen Examples and Prompts

For the Add Transaction screen:

Create a transaction entry form with :

– Large amount input field at top (numeric keypad)

– Category selection (grid of icon buttons: Food, Transport, Shopping, Bills, Entertainment, Other)

– Date picker (default to today)

– Optional note field

– Save button at bottom (full width, prominent)

– Cancel button in header

– Expense/Income toggle at top

For the Onboarding screens:

Create 3 onboarding slides for budget app :

Slide 1: Welcome screen with app icon, tagline “Take Control of Your Money”, illustration of person with piggy bank

Slide 2: “Track Every Expense” with illustration of receipt/phone, text about easy transaction logging

Slide 3: “Understand Your Spending” with charts/graphs illustration, text about insights

Each with Skip/Next buttons, progress dots at bottom

The AI-generated screens were beautiful and on-brand. Minor tweaks took another 20-30 minutes per screen

Creating Interactive Prototype

Figma’s prototyping features let you link screens together to simulate the app. I connected:

• Onboarding slides with “Next” buttons
• Authentication flow (signup → dashboard, login → dashboard)
• Dashboard actions (tap “Add” → Add Transaction screen)
• Navigation bar (tap icons to switch between main screens)
• Back buttons and cancel actions

The interactive prototype became crucial for testing with friends and identifying UX issues before building

Deliverable: Complete UI design in Figma with 13 polished screens, a comprehensive design system, and an interactive prototype ready to be converted into a real app

Step 4: Building the App with FlutterFlow (24 Hours)

This is where the magic happens. Taking your designs and turning them into a functional app

Why FlutterFlow?

After testing several no-code platforms (Adalo, Bubble, Thunkable), I chose FlutterFlow because :

• It generates actual Flutter code (can be customized later)
• Best Figma integration
• Firebase built-in (database, authentication, storage)
• True native apps (not web wrappers)
• Best performance of all no-code tools I tested
• Active community and excellent documentation

Importing Figma Designs (1 Hour)

FlutterFlow has a Figma import feature that’s surprisingly good :

1. In Figma, select all frames you want to import
2. Copy the Figma file link
3. In FlutterFlow, go to “Import from Figma”
4. Paste link and select frames
5. FlutterFlow converts designs to widgets

The import wasn’t perfect—some spacing needed adjustment, and complex auto-layouts sometimes broke. But it saved hours compared to rebuilding everything from scratch

Pro tip: Before importing, organize your Figma layers with clear naming. FlutterFlow reads layer names as widget names, making it easier to find and edit elements

Setting Up Firebase Backend (2 Hours)

FlutterFlow makes Firebase integration incredibly simple :

1. Click “Firebase Setup” in FlutterFlow
2. Follow the wizard to create a Firebase project
3. FlutterFlow automatically configures authentication and Firestore

Database Structure I Created :

Users Collection:

– userId (auto-generated)

– email

– displayName

– monthlyBudget (number)

– createdAt (timestamp)

Transactions Collection:

– transactionId (auto-generated)

– userId (reference to Users)

– amount (number)

– category (string)

– type (string: “income” or “expense”)

– note (string, optional)

– date (timestamp)

– createdAt (timestamp)

Categories Collection:

– categoryId (auto-generated)

– name (string)

– icon (string)

– color (string)

– type (string: “expense” or “income”)

FlutterFlow’s visual database builder made this easy. I literally drew out the relationships between collections by clicking and dragging

Building User Authentication (2 Hours)

Firebase Authentication handles all the complex security:

1. Enable Email/Password authentication in Firebase Console

2. In FlutterFlow, add “Login” action to login button:
   • Action: Authenticate User
   • Email field: [email input field]
   • Password field: [password input field]
   • Success action: Navigate to Dashboard
   • Error action: Show error message
3. Similarly set up Sign Up action:
   • Action: Create Account
   • Email, Password, Confirm Password fields
   • Success: Navigate to Dashboard
   • Error: Show validation error
4. Password Reset:
   • Action: Send Password Reset Email
   • Email field input
   • Success: Show confirmation message

The authentication was working in under 2 hours. Firebase handles all the security, email verification, and password encryption automatically

Building Core Functionality (12 Hours)

This was the longest phase. Making each screen actually work

Dashboard Screen (3 hours):

• Query Firestore for current user’s transactions this month
• Calculate total income, total expenses, remaining budget
• Display recent transactions (limit 5, ordered by date descending)
• Create pie chart showing expenses by category
• Implement pull-to-refresh

Add Transaction Screen (3 hours):

• Create form with validation (amount required, category required)
• Category selection with visual icons
• Date picker (default to today)
• On Save button: Create new document in Transactions collection
• Navigate back to Dashboard and refresh data

Transaction List Screen (2 hours):

• Query all transactions for current user
• Display in list with infinite scroll
• Group by date (Today, Yesterday, This Week, Earlier)
• Tap transaction to view/edit details
• Swipe to delete with confirmation dialog

Edit Transaction Screen (2 hours):

• Load existing transaction data into form
• Allow editing all fields
• Save updates to Firestore
• Delete transaction option

Categories Screen (1 hour):

• Display all expense categories
• Show total spent in each category this month
• Color-coded progress bars
• Tap to see all transactions in that category

Profile Screen (1 hour):

• Display user email
• Set monthly budget (editable)
• Basic settings (coming soon placeholders)
• Logout button (clears session, returns to login)

Adding Polish and Micro-Interactions (3 Hours)

Small details that make the app feel professional:

• Loading spinners when querying database
• Empty states (“No transactions yet. Tap + to add your first expense!”)
• Success messages (Toast notifications)
• Form validation errors (red text below invalid fields)
• Smooth transitions between screens (slide animations)
• Bottom navigation highlighting (current screen indicator)

Testing on Real Devices (3 Hours)

FlutterFlow has a testing app that lets you preview your build instantly:

1. Download “FlutterFlow” app from App Store or Play Store
2. Scan QR code from FlutterFlow dashboard
3. App loads on your phone in seconds

I tested thoroughly:

• Created account
• Logged in and out multiple times
• Added 20+ test transactions
• Edited and deleted transactions
• Checked all navigation flows
• Tested form validation (tried submitting empty forms, invalid emails, etc.)
• Verified database updates in Firebase Console
• Tested on both iPhone and Android devices

Issues I Fixed:

• Date picker didn’t work on Android → Switched to different date picker widget
• Transaction list loaded slowly → Added pagination (load 20 at a time)
• Keyboard covered input fields → Added automatic scroll behavior
• Category icons looked blurry → Replaced with higher resolution assets

Deliverable: A fully functional app running on real devices with all core features working, data persisting to Firebase, and a polished user experience

Step 5: Publishing Your App (8 Hours)

The finish line! Getting your app into the hands of users

Preparing for App Store Submission

Both Apple and Google have specific requirements. Here’s what you need :

App Assets to Create :

1. App Icon (1024×1024px)
2. Splash Screen
3. App Screenshots (multiple sizes for different devices)
4. Feature Graphic (1024×500px for Google Play)
5. Privacy Policy (required!)

I used Figma to create all visual assets. For the privacy policy, I used a template generator (https://www.privacypolicygenerator.info/) and customized it for my app

App Store Screenshots: I took screenshots of all major features on actual devices, then added marketing text overlays in Figma :

• Track Every Expense” (Dashboard screenshot)
• “Categorize Smartly” (Categories screen)
• “Understand Your Spending” (Transaction list)
• “Set Budget Goals” (Profile with budget setting)

Building Release Version in FlutterFlow

FlutterFlow makes this straightforward :

1. Go to “Build” section
2. Select “iOS” for App Store build
3. Upload App Store Connect credentials
4. Hit “Build”
5. Wait 20-30 minutes for build to complete
6. Download IPA file or deploy directly to TestFlight

Repeat process for Android:

1. Select “Android” build
2. Generate signing key (FlutterFlow guides you through this)
3. Build AAB file
4. Download for Google Play upload

Cost Note: Free tier FlutterFlow builds work fine, but paid plans ($30/month) get faster build times and direct store deployment

Submitting to Google Play Store

Google Play is faster and more forgiving:

1. Create Google Play Developer account ($25 one-time fee)

2. Create new app listing

3. Fill out store listing:
   • App name: “BudgetFlow”
   • Short description (80 chars)
   • Full description (4000 chars max)
   • Screenshots (min 2, I uploaded 5)
   • App icon
   • Feature graphic
   • Category: Finance
   • Content rating: Everyone
4. Upload AAB file

5. Complete content rating questionnaire

6. Set up pricing (Free)

7. Add privacy policy URL

8. Submit for review

Review Time: Google typically reviews in 1-3 days. Mine was approved in 18 hours !

Submitting to Apple App Store

Apple’s process is more involved:

1. Create Apple Developer account ($99/year)

2. Create App ID in Apple Developer portal

3. Set up App Store Connect listing:
   • App name
   • Subtitle
   • Description
   • Keywords (important for search)
   • Screenshots (multiple sizes: 6.5″, 5.5″, iPad)
   • App icon
   • Age rating
   • Privacy policy
4. Upload build via TestFlight (from FlutterFlow)

5. Submit for review with explanation of app purpose

Apple Review Time: Typically 1-3 days. Be prepared for possible rejection and resubmission. Apple is strict about :

• Privacy policy completeness
• Functionality (must match description)
• Design quality
• Use of Apple’s standard UI pattern

My app was initially rejected because I didn’t explain how I handle user data in enough detail. I updated the privacy policy and app description, resubmitted, and was approved 24 hours later

Common Rejection Reasons (and How to Avoid Them)

Google Play:

• Missing privacy policy → Always include one
• Misleading screenshots → Show actual app features
• Broken functionality → Test thoroughly
• Policy violations → Read Play Store policies

Apple App Store:

• Incomplete metadata → Fill out every field
• Low-quality interface → Follow Apple Human Interface Guidelines
• Missing functionality → All features in screenshots must work
• Privacy issues → Clear explanation of data usage
• Crashes → Extensive testing required

Deliverable: Your app live on the App Store and/or Google Play Store, available for download by anyone in the world !

Lessons Learned & Pro Tips

After completing this 48-hour challenge, here’s what I learned :

What Worked Well

1. AI-generated designs saved hours – Let AI do the first 80%, then customize the final 20%
2. Design system first – Creating reusable components made subsequent screens much faster
3. FlutterFlow’s Figma import – Not perfect, but saved significant time
4. Firebase integration – Backend setup that would take weeks took 2 hours
5. Testing early and often – Caught bugs when they were easy to fix

What I’d Do Differently

1. Start with simpler features – I cut several features mid-project to meet the deadline
2. Learn FlutterFlow basics first – I spent the first 2 hours of building phase learning the tool
3. Prepare assets earlier – Store submission prep could have been done during development
4. Use more AI prompts – I manually designed some screens that AI could have generated
5. Plan database structure better – Made schema changes mid-build that required rework

Common Mistakes to Avoid

Design Phase:

• Don’t skip the research phase (tempting when you’re excited to design)
• Don’t design features you won’t have time to build
• Don’t ignore mobile design constraints (thumb zones, safe areas)

Build Phase:

• Don’t customize everything – Use default widgets when possible
• Don’t forget to test on real devices (emulators miss issues)
• Don’t ignore performance from the start (harder to fix later)
• Don’t skip user authentication security (Firebase handles this well)

Publishing Phase:

• Don’t submit without thorough testing (rejection delays launch)
• Don’t use placeholder text in store listings (looks unprofessional)
• Don’t forget privacy policy (required, and reviewers check)
• Don’t expect instant approval (plan for 2-5 days review time)

Quick Wins for Faster Development

1. Use Figma templates – Start with existing mobile app design templates
2. Copy proven UX patterns – Don’t reinvent navigation or form layouts
3. Use Firebase authentication – Don’t build your own login system
4. Leverage FlutterFlow marketplace – Pre-built components and templates
5. Use AI for content – ChatGPT for button labels, error messages, help text
