Contact: Hanif Laarabi, France. Replies are written in French or English. Please include the app version, your iPhone and Watch models, the system versions and the steps to reproduce the problem. Remove sensitive data from screenshots. Never send a password or an Apple key.

Installing a test version

Get an invitation for a build that is actually available.
Install TestFlight from the App Store on the iPhone paired with your watch.
Accept the invitation, install SpearfishOS, then the Watch companion offered.
Read the release notes before testing.

A build must be processed by Apple and assigned to a test group. A test request does not automatically create an invitation. External testing may require Apple's beta review.

Understanding Watch compatibility

The app targets watchOS 10 or later. Measurements depend on API availability, the watch model and the permissions granted. The range shown in the app is the reference for the build you use; access down to 40 m has not been granted to SpearfishOS. Without an available sensor, only the timer is offered. No model that is not designed for diving will be turned into one.

A dive does not sync

Open both apps on the paired devices, check their connection and use Retry synchronization in the iPhone settings. The transfer may be delayed. Update both apps together and keep the Watch copy until the transfer is confirmed.

Pro, restoring and cancelling

Use Restore purchases on the Pro screen. Subscriptions are managed in iPhone Settings → your Apple Account → Subscriptions. Refund requests go through Apple's service. For how the plan works, see the terms.

Exporting or deleting data

The logbook is local: the developer has no remote copy. Export before deleting the app and check your system backups. See the privacy policy for limits and requests about emails.
