Frequently asked questions
Q. Workouts aren't being saved to Apple Health.
A. First, make sure "Record to Health" is ON in the preset's edit screen. Then check write permission on the device where you performed the workout. iPhone and Apple Watch permissions are managed separately, so one can be granted while the other is not.
- If you worked out on iPhone: check that writing workouts is allowed under iPhone Settings → Health → Data Access & Devices → Round.
- If you worked out on Apple Watch: check on the Apple Watch itself under Settings → Health → Apps → Round (wording and hierarchy may differ between watchOS versions). Even if permission is granted on iPhone, workouts recorded on the Watch are not saved while the Watch side remains ungranted.
On the first save, the device you used will prompt for HealthKit write permission. If you already chose "Don't Allow", the prompt will not appear again — change it from the settings above.
Q. Measured calories from my Apple Watch don't appear in my history.
A. Calorie display in your history is a Round Pro feature, in versions where Round Pro is available. A measured value is attached only to sessions performed on the Apple Watch, and only when the active energy measured during that workout could be retrieved. When it could not, the estimated calories are shown instead, provided a body weight is available. Please check the following.
- Whether "Record to Health" is ON for the preset you used. When it is OFF, the Apple Watch does not start a workout, so no measured value can be obtained.
- Whether reading Active Energy is allowed on the Apple Watch itself. You can check this on the Apple Watch under Settings → Health → Apps → Round (wording and hierarchy may differ between watchOS versions).
- Whether the session was performed on the iPhone only. iPhone-only sessions never carry a measured value and show the estimate instead.
- Whether a body weight is set. The estimate needs one, so if you have neither entered a weight manually nor allowed the App to use the Apple Health value, no calorie figure appears when there is no measured value (the App shows "Set your weight to see the prediction" instead).
Note that HealthKit deliberately does not let an app distinguish "read access was not granted" from "there is no matching data". The absence of a measured value alone therefore does not tell you whether permission was granted, so please work through the checks above.
To review permissions on the iPhone side (writing workouts, and reading the body weight used for calorie estimation), go to iOS Settings → Health → Data Access & Devices → Round. That is a separate setting from Active Energy read access on the Apple Watch.
Q. Presets or history aren't syncing with Apple Watch.
A. Confirm that the iPhone and Apple Watch are paired to the same Apple ID and that Round is up to date on both devices. Sync uses Apple's WatchConnectivity and may take a moment — keeping the app open for a while can help. If the problem persists, reinstall the Watch app.
Q. The home-screen widget isn't updating.
A. Widgets refresh on iOS's own schedule. Opening the App once pushes the latest snapshot to the widget via App Group.
Q. How do I delete presets or history?
A. Swipe to delete or use edit mode on each screen. To remove everything, uninstall Round from your iPhone — all data saved in SwiftData / UserDefaults / App Group will be deleted (data previously written to HealthKit remains on the Apple Health app side).
Q. Will my data carry over to a new device?
A. The App does not offer iCloud sync, so presets and history are not migrated when changing devices. We recommend backing up important configurations (e.g., via screenshots) beforehand.
