How to read this
Each section is an archetype — not a single app, but a pattern. The prompts, stacks, and launch playbooks below reflect what founders actually ship in that category. Pick one that resonates and read the deeper vertical guide linked within.
1. Habit & routine trackers
Tightest fit for AI generation. Small feature set, clear subscription model, loyal niche audiences. Typical apps: habit tracker for ADHD, morning routine for creatives, sobriety check-in, faith-based daily practice.
- Stack: Expo Router + MMKV + Supabase sync + expo-notifications + RevenueCat.
- Build time: 1 weekend to TestFlight.
- Launch: one niche community (subreddit / Discord) first.
- Deep dive: Build a Habit Tracker App in 10 Minutes.
2. Fitness & wellness apps
Harder than habit trackers because of HealthKit and charting, but still very AI-buildable. Typical apps: postpartum recovery logger, bouldering progress tracker, over-50 strength programs, breathing / meditation timers.
- Stack: Expo + expo-health or expo-health-connect + Supabase + RevenueCat.
- Build time: 1–2 weeks — HealthKit integration adds real work.
- Launch: niche first (“for postpartum” beats “for everyone”).

3. Niche marketplaces
Two-sided apps with a wedge: vintage furniture in one city, wedding vendors, tutoring services, specialty food. The hard part is liquidity, not the code — AI handles the buyer/seller flows fine.
- Stack: Expo + Supabase + Stripe Connect + Supabase Realtime for messaging.
- Build time: 1–2 weeks to MVP; months to liquidity.
- Launch: one city + one niche before expanding anywhere.

4. Niche social networks
Social for a specific identity, profession, or interest — always narrow in v1. Typical apps: poetry community, run-club network, sobriety support, creative daily-prompt app.
- Stack: Expo + Supabase (with realtime) + moderation pipeline + RevenueCat.
- Build time: 2 weeks to launchable — moderation is the work.
- Launch: hand-invited first 100, all inside the niche’s existing community.
- Deep dive: How to Build a Social Networking App Without a Developer.
5. Booking & appointment apps
Vertical-specific booking for one profession in one city: barbers in Brooklyn, physical therapists in Austin, tutors in Chicago. The incumbents are generic; the niche apps win.
- Stack: Expo + Supabase + Stripe + expo-notifications.
- Build time: 1 week including Stripe deposit setup.
- Launch: 10 providers, hand-onboarded, one profession.
- Deep dive: Build a Booking / Appointment App in Under an Hour.
6. Branded e-commerce apps
Small brands with loyal customers who want a real app, not a wrapped Shopify web view. Typical apps: boutique coffee subscription, streetwear drops, indie book publisher, curated home goods.
- Stack: Expo + Shopify API (or Supabase custom) + Stripe + Shippo.
- Build time: 1–2 weeks.
- Launch: existing customer list + App-Store-only discount.
- Deep dive: How to Build an E-commerce Mobile App Without Code.
7. B2B SaaS mobile companions
Mobile app for an existing SaaS product: admin stays web, mobile is for the core user job. Typical apps: task management for small teams, field-sales CRM companion, invoice & expense capture.
- Stack: Expo + Clerk (Organizations) + Supabase (RLS by workspace) + Stripe web for billing.
- Build time: 2 weeks including multi-tenancy plumbing.
- Launch: existing SaaS customer base + mobile launch to waitlist.
- Deep dive: How to Build a SaaS Mobile App with AI.
Common threads across every archetype
- Narrow niche. “For X” outperforms “for everyone” in every category.
- Expo + Supabase as the default stack. Cheapest, fastest, widest library support, best AI tooling match.
- RevenueCat for monetization (subscriptions + IAP), Stripe for anything physical or out-of-app.
- Community-first launches. Reddit, Discord, niche Twitter, not App Store browse.
- Small v1 feature set. 3–6 screens, one core loop, paywall from day one.
- Offline-first where it fits. Habit, fitness, productivity — MMKV + Supabase sync.
- Iteration through both the AI builder and Cursor. Generate the scaffold, edit the edges.
