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 the app access the phone's built-in step counter?

Yes. Fastshot generates code using Expo sensors and pedometer APIs to read step data directly from the device's built-in motion sensors.

Does it support GPS route tracking for runs?

Describe route tracking in your requirements and Fastshot generates map-based route recording with distance, pace, and elevation data using Expo Location.

Can users set daily and weekly activity goals?

Yes. The generated app includes goal-setting screens where users define daily targets for steps, active minutes, or distance with visual progress indicators.

Does it show trends over weeks and months?

Fastshot generates historical dashboards with charts showing activity patterns over days, weeks, and months so users can spot trends and stay motivated.

Can users share achievements with friends?

Include sharing in your description. Fastshot generates achievement cards and social sharing so users can post milestones to friends or social media.
