Battivra
Your iPhone's battery, on your Apple Watch.
The last reported level
See your iPhone's battery level and whether it is charging, right on your wrist.
Always honest about age
Every reading shows how old it is. Open Battivra on your Apple Watch and it asks your iPhone for a new one.
Both ways
Your iPhone shows your Apple Watch's battery too, while Battivra is open on the watch.
Private by design
No account, no ads, no analytics. Readings stay on your iPhone and Apple Watch and are never sent to a server.
Requires an iPhone with iOS 17 or later and a paired Apple Watch with watchOS 10 or later.
