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 users track time across multiple clients or projects?

Yes. The generated app includes project and client categorization so users can assign time entries to specific contexts and generate per-client reports.

Does it support both timer and manual entry?

Describe both modes. Fastshot generates a running timer for active tracking and manual entry forms for logging time after the fact.

Can I generate exportable time reports?

Include reporting in your description. Fastshot generates summary views by project, client, or date range with CSV export for invoicing and accounting.

Are there weekly and monthly summaries?

Yes. Fastshot generates dashboard views that aggregate time by day, week, and month with visual charts showing how hours are distributed.

Does it work offline?

The app stores time entries locally and syncs with Supabase when connectivity returns. Users can track time anywhere without worrying about signal.

Why Build a Time Tracker App?

Freelancers, agencies, and remote workers rely on time tracking apps to log hours, bill clients accurately, and understand how they spend their working day.

A time tracker needs start/stop timers, project and client assignment, manual time entry, reporting dashboards, and export capabilities for invoicing.

Fastshot generates a native time tracker with one-tap timers, project categorization, detailed reports, and exportable data — everything freelancers and teams need on iOS and Android.

You can build this time tracker app using our [AI mobile app builder](/ai-app-builder) — describe what you want and get a working native app in minutes.
