Hi, I would like to set the times manually, say every hour or so. The reason is unrelated to tech more of a personal thing. I'm using androidso you want an app that will just randomly or at set times cause it to vibrate without bringing up a notification of some kind that takes over the screen?
There are ways to do this, but first tell me a couple of things.
In particular, why do you need to do this? As there might be a better option than what you think you need.
Secondly, what operating system are you using? iOS or Android?
