WKHaptics is a tool for WatchOS developers to experiment with the various types of haptic feedback available on AppleWatch.

This watch-only app allows you to play all haptics available to developers, including location based haptics that require background location tracking. Use the slider or Digital Crown to adjust the timing interval between firing each type of haptic.

Note that, according to Apple's Developer Documentation: If the haptic engine is already engaged calling another haptic signal, the system stops the current feedback and imposes a minimum delay of 100 milliseconds before engaging the engine to generate the new feedback. Using the haptic engine consumes power, and using the engine too much may create a noticeable drain on the Apple Watch battery.

Note: If location tracking is not permitted, the other types of haptics can still be experienced.
