Heart rate and calories don't show up

An iPhone has no heart-rate sensor of its own. Live heart rate, heart zone and calories appear when a sensor your iPhone reads is connected, such as heart-rate AirPods or a Bluetooth chest strap, and Lunge is allowed to read from Apple Health (Settings › Health › Data Access & Devices › Lunge).

Changing the language

Lunge follows your iPhone's language. To use another one — English, Spanish, German or Turkish — tap the gear on My workouts and pick it there.

Moving to a new iPhone

Your workouts live on your iPhone and come across with an iPhone backup or transfer. Lunge has no account to sign in to.

Deleting your data

Delete the app. Workouts already saved to Apple Health stay there and can be deleted in the Health app. See the privacy policy for what Lunge keeps.
