3DMassage works exactly as it says it does, and a good job at that, although some people somehow downloaded 3DMassage not realizing it was for an Apple Watch or even reading the instructions at all. Anyways, it’s a fun little app and works how you would think it would, I’ll try and report back here if I have any bugs later.
Issue: When controlling the intensity, there isn’t really a smooth flow of vibration when on any of the lower settings beneath maximum. When at maximum, the vibration feels like you have an alarm going off or you have a phone call, where as on the lower settings it can feel like the motor is sort of varying the ratio of how much the motor is on/off and not controlling strength. For example, minimum can feel (and sound, unnervingly btw) like the motor in your phone is sputtering on and off with it being off most the time, while high is the same but vise-versa. Although there may not be a way to control the “strength” of the motor inside of smart devices, it still feels like it can be improved upon a bit. Anyways, keep improving and makin’ apps. If it’s still Christmas when you’re reading this, then Merry Christmas.
