Before you start

A few useful answers.

Can I use SoloFit without an Apple Watch?+

Yes. iPhone supports plans, exercise guidance, workout execution and history on its own. Apple Watch offers another way to train, with both devices syncing through their paired connection.

What syncs between my phone and watch?+

Download phone-managed plans to your watch. Completed watch sessions sync through the phone after reconnecting. Once a phone workout has synced, the watch updates its daily summary. A session stays on the device where it started; there is no mid-session handoff.

Can I keep training without a connection?+

The watch can run downloaded sessions and show its built-in exercise demonstrations offline. A phone workout already started and saved locally can continue during a temporary loss of connection. Records sync after reconnecting. Plan generation and AI conversations need an internet connection.

Will AI change my current plan automatically?+

No. New plans and adjustments are presented as proposals for you to review and confirm. The coach can explain your plan, discuss alternatives and organize a written plan. It asks for clarification when needed.

Do I have to authorize Apple Health?+

Basic set logging does not require Health access. With authorization, the watch can record workouts and display heart rate, active energy and the current session’s heart-rate trend. Missing readings are not filled in with invented values.

Can I manage language and personal data?+

The app supports English and Chinese, light and dark themes, and common measurement units. Watch language can be set independently. Account settings include data export and account deletion; coach memory has its own viewing and management controls.
