1. I'm not positive if it was from this app but I can't find any other cause.Excellent it is really good and does exactly what it says and of your swip it sideways its got 5 different vibration settings you can swip it forward or backwards to the vibration you wantI use it for my thumbs.
2. been using this app for over 2 months and appears to be free of malware and other malicious programs got to give this program 5 stars out of 5 its free, it works well, and has saved me from a few extra days of pain.
3. However, banner AND popup ads? That's a yikes.randomly stops for no reason, the vibration modes are the same things different names, annoying ads.
4. I squeeze the phone like a stress ball and it works good for my palms and thumbs when my hands cramp after work.
5. overall the vibration will only make your hand numb and isn't strong enough to massage anythingIt did do very well for my migraines, though my phone is unable to virbate anymore when on silent or when my notification volume is down.
6. Also experimental option of basic audio waveforms to play in sync with vibration pulse, having the frequency adjustable.
7. If it could only work while the screenlock is on, and have a timing option... Would totally pay for it.Yeah, a good app that does what it says.
8. Glitches in UI in transition; double tapping on program leaves the vibrator on and no away to stop.
9. i like the different modes and the speed slider.
10. i'm better off using a scrunchie on a game controller.timered pop up every third button.
11. I would like an improvement, however: added setting of pulsing by cycles per sevond (Hz).
