Bottomtime Support

Check that your dive computer’s depth and duration data is available through the “Health” app, since Bottomtime Pro imports from “Health” and compatible devices, then confirm Bottomtime has permission to read that data in Settings.

Automatic iCloud sync is a Bottomtime Pro feature, so confirm your subscription or lifetime unlock is active, then check that both devices are signed in to the same Apple account with iCloud turned on.

Open the export option in Bottomtime and choose UDDF, CSV, or PDF; the PDF export can also include an instructor signature with Bottomtime Pro.

Use the “Restore Purchases” option in Bottomtime’s settings while signed in with the same Apple account used for the original purchase.

Add the widget from the “Home Screen” editor after Bottomtime Pro is active; it may take a moment for a new widget to appear in the widget gallery.

The latest version is 1.0, released on June 22, 2026. To update, open the App Store, tap your profile picture, pull down to refresh, then tap Update next to Bottomtime. You can also turn on automatic updates in Settings › App Store.

Subscriptions are managed by Apple. Open Settings, tap your name, then Subscriptions, and choose Bottomtime to change or cancel your plan. Cancel at least 24 hours before renewal to avoid the next charge; deleting the app does not cancel it. Refund requests go through reportaproblem.apple.com and are decided by Apple.

Open Settings › Notifications › Bottomtime and make sure Allow Notifications is on. Then check that a Focus mode or the Scheduled Summary is not holding them back, and that the reminder is turned on in Bottomtime. Reminders are scheduled on your device, so they work without an internet connection.

Open Settings › Privacy & Security › Health › Bottomtime (or, in the Health app, tap your profile picture, then Apps) and turn on the data types you want to share. Bottomtime only reads or writes what you allow, and you can change it at any time.

Open Settings › Privacy & Security › Camera (or Photos) and turn on Bottomtime. The pictures you attach stay in the app and are never sent to us.

In Bottomtime, use the option to delete your data in the app’s settings, where available. Deleting the app removes the data stored on that device. To remove the copy kept in iCloud, go to Settings › [your name] › iCloud › Manage Account Storage, select Bottomtime and delete its data.
