Frequently Asked Questions

Is WatchCheck a benchmark or optimizer?

No. WatchCheck is a tester and reporter for Wear OS app usability checks. It is not a benchmark, cleaner, optimizer, scanner, or medical tool.

Does WatchCheck need a phone companion app?

No. WatchCheck is a standalone Wear OS utility that runs directly on the watch.

Does WatchCheck send device reports anywhere?

No. Device info is shown locally. A report leaves the app only if the user explicitly copies or shares it.

Does WatchCheck run in the background?

No. WatchCheck has no services, wake locks, polling, or background sensor listeners. Haptics fire only after direct user taps.
