Fastshot is an AI-powered mobile app builder that generates production-ready native iOS and Android apps from text descriptions. Built on Expo and React Native, it handles design, code generation, backend setup, and App Store deployment — no coding required.

Do I need coding experience to use Fastshot?

No. Fastshot generates complete mobile apps from plain English descriptions. No coding, design, or technical skills are required. Simply describe your app idea and Fastshot builds it.

What kind of apps can Fastshot build?

Fastshot builds native iOS and Android mobile apps across all categories including fitness, social, productivity, business, education, e-commerce, and lifestyle apps. Apps include UI, navigation, backend (Supabase with PostgreSQL), authentication, push notifications, and monetization.

Can I deploy my app to the App Store and Google Play?

Yes. Fastshot compiles APK and AAB files for Google Play and IPA files for the App Store in the cloud. It also generates store metadata, screenshots, and submission documentation for both platforms.

Do I own the source code?

Yes. You get full ownership of the generated React Native and Expo source code. You can export it, modify it in VS Code or any IDE, or hand it to a developer. Zero vendor lock-in.

How is Fastshot different from web app builders like Bolt.new or Lovable?

Bolt.new and Lovable generate web applications that run in a browser. Fastshot generates true native mobile apps using React Native and Expo that compile to iOS and Android binaries with full device API access including camera, GPS, push notifications, and biometrics.

Can sellers create listings with multiple photos?

Yes. Fastshot generates multi-image listing creation with descriptions, pricing, categories, and condition details — everything a seller needs to showcase their products.

Is there buyer-seller messaging?

Absolutely. Fastshot generates in-app messaging powered by Supabase real-time subscriptions so buyers and sellers can negotiate, ask questions, and coordinate.

How do I handle payments?

Fastshot generates the checkout UI and order flow. Post-export, integrate Stripe Connect or another marketplace payment platform for secure, commission-supporting transactions.

Can buyers leave reviews for sellers?

Include reviews in your description. Fastshot generates rating and review systems that build trust and accountability in your marketplace community.

Does it support search and category filtering?

Yes. Fastshot generates search with category filters, price ranges, location proximity, and sorting options so buyers find exactly what they are looking for.
