8 guided steps from
idea to the App Store.

Phase 01 — Idea

Describe your app idea.

Answer a few simple questions: What does your app do? Who is it for? What features should it have? Capplyn guides you through each one — no blank-page anxiety.

• Pick a category (fitness, food, social, etc.)
• AI suggests app names based on your concept
• Describe your target user in plain English
• Choose features from suggestions or add your own
• Pick a monetization model (free, subscription, paid, etc.)
• Review your app brief before moving on

Phase 02 — Audience

Understand who you're building for.

Capplyn AI analyzes your idea and recommends a user persona, content tone, and what makes your app different. You confirm or adjust.

• AI-generated user persona based on your description
• Suggested content tone (casual, professional, playful, etc.)
• Key differentiators identified automatically
• Everything saved to guide design decisions later

Phase 03 — Competitive

See what else is out there.

AI scans the app stores for 3–4 competitors and shows you what they do. You tell Capplyn what makes yours different — and that insight shapes everything downstream.

• Automatic competitor research with app icons
• Side-by-side comparison of features and positioning
• You define your unique angle in your own words
• Your differentiator is woven into screens and copy

Phase 04 — Design

AI designs every screen.

Pick a visual vibe, choose a color palette, and watch Capplyn generate your entire app — screens, icons, layouts. Review each screen and request changes until it's right.

• Choose a visual vibe (minimal, vibrant, elegant, etc.)
• AI generates a color palette to match
• Custom app icon designed by AI
• Screen layouts generated based on your features
• Request extra screens if you need more
• Review and approve each screen design individually

Phase 05 — Assemble

Code is written automatically.

Capplyn turns your approved designs into working React Native code. It scaffolds the project, writes every screen, and wires up navigation — all without you touching a code editor.

• Full React Native + Expo project scaffolded
• Each screen coded to match your approved design
• Navigation and data models wired automatically
• Preview mockups in a phone frame before proceeding
• Request redesigns on any screen if it's not right

Phase 06 — Build

Connect your accounts and build for your phone.

To publish on the App Store, you need an Apple Developer account ($99/year). Capplyn walks you through connecting it, then compiles the installable app in the cloud. Android support is coming soon.

• Apple Developer account credentials (securely stored)
• Automated iOS certificate and provisioning setup
• Native build triggered on cloud infrastructure
• Real-time build progress tracking
• Automatic retry and diagnosis if something goes wrong

Phase 07 — Test

Test on your real phone.

Your app is sent to TestFlight so you can install it on your iPhone and try it for real. Found a bug? Tell the AI — it'll diagnose and fix it automatically.

• App delivered via TestFlight
• Install on your real iPhone to test
• Testing checklist to guide your review
• AI-powered bug diagnosis and auto-fix
• Smart routing: instant fixes via OTA, bigger changes via rebuild

Phase 08 — Launch

Submit to the app stores.

Capplyn generates your store listing, screenshots, and privacy policy — then submits to Apple for review. You just wait for approval.

• AI-generated store listing and keywords
• Screenshot generation for required device sizes
• Privacy policy auto-generated based on your app's features
• One-click submission to App Store review
• Typical Apple review: 24–48 hours
