Frequently Asked Questions

Clear answers regarding mobile installation, offline capabilities, privacy, and account synchronization.

Q:Is Fit Host a web application or a native mobile app?

Fit Host is a native mobile application engineered with Flutter for Android and iOS. This website is the official product launch and update portal where you can find download links, version releases, setup guides, and support.

Q:Can I use Fit Host offline without an active internet connection?

Yes. Fit Host was architected with an offline-first foundation. All workouts, hydration logs, and settings write immediately to an embedded Drift SQLite database on your device. When internet connectivity is available, changes automatically synchronize to Supabase cloud storage.

Q:Do I have to create an account to test or use Fit Host?

No. Fit Host offers a complete Guest Mode. You can log exercises, track water, and explore all workout categories immediately without creating an account or providing an email address. If you choose to sign up later, all your existing guest records automatically migrate to your cloud account.

Q:How does cloud sync protect my personal health data?

Cloud data is stored in PostgreSQL and governed by Supabase Row Level Security (RLS) policies. Only your verified authentication token can read or modify your data. Service-role privileges are never exposed to clients, and your workout data is never monetized or shared.

Q:Where can I download Fit Host today?

You can download the verified Android Release APK directly from this website. Official Apple App Store and Google Play Store listings are currently in preparation.
