Seems like everyone agrees on this app. May I ask, How is the intensity, another user above reported that it is too low to feel. Are you able to feel the haptic vibration on your wrist? Does the watch needs to be connected to the phone to work? Is there anyway to set it up independely installing it and using it on the watch without the need of the phone? have you tested the battery, how long can the watch last with continuous vibration? currently my gamrin watch lasts approximately 10 hours, which is great. are you able to use some sort of shortcut to quickly turn on and off the vibration haptic on apple watch? also is there any buzz sound or somesort of sound coming from the watch? if the apple watch work I will definitely switch to it, if it only lasts 8 hours that should be enough, I can buy another watch as a backup and wear it in case the first watch battery runs off
