Common questions about manual logging, read-only Apple Health import, the free version 1.3 update, existing purchases, and local data.
Depthline stores manual readings, imported Health readings, preferences, target settings, and app state locally on your device. A derived trend snapshot may also be shared locally with Depthline widgets. Depthline does not send weight readings to a developer-operated server.
No. Depthline does not require an account, login, profile, or social feature.
No. Depthline can read approved body-weight data when you allow it, but does not write body-weight readings to Apple Health.
Yes. Manual logging is included and remains available when Health access is declined or unavailable.
A useful trend needs enough readings over time. Depthline keeps early states cautious instead of presenting a few readings as a settled signal.
Version 1.3 is completely free: Apple Health import, unlimited manual logging, all History and Voyage ranges, every vessel style, CSV export, widgets and Shortcuts. The update is submitted to App Review; availability follows approval.
Version 1.3 includes all former Plus features for everyone. Existing purchasers keep every range and vessel style, with no new payment or restore step. Your readings and settings remain intact when you update.
No. Health synchronization, manual logging, the complete Logbook, editing, deletion, and CSV export remain available without Plus.
On version 1.2, open Settings > Depthline Plus > Restore Purchases using the Apple Account that made the purchase. Version 1.3 removes the purchase flow because all features are included. Apple retains your transaction history.
No. Depthline is a personal trend utility, not a medical device, diagnosis, treatment, diet plan, or coaching product.
Depthline is intentionally narrow: personal weight trend, optional read-only Health import, manual logging, and honest sparse-data states. For a question not covered here, use the contact page or email support.
