The mouse shaker does what it says. It shakes the mouse, on the timer you set it for, as little as every 30 seconds. I would give it 5 stars if it would “shake” while screen is off. It does require a haptic enabled device.

App is free and does the job. I thought it didn’t work at first but it does. Is it annoying to troubleshoot the app before it works? Yes but it’s FREE. To the people who say this doesn’t work, I thought so too, but it is finicky so try these steps:1) MAKE SURE YOUR SOUND AND HAPTICS ARE ALL ON. If they are not on at all you won’t get vibrations and the app won’t work.2) if it still doesn’t work restart your iPhone. I had to do this 3) if it still doesn’t work uninstall and reinstall the app4) I ONLY use the 30 seconds option. YOU MIGHT NOT FEEL THE VIBRATION IF YOU HOLD IT IN YOUR HAND, so put it on a hard surface and put your mouse on top. I had to leave it running for a minute before it worked.

So at first I thought it was not working but I realized with my case on my phone the vibration is just not enough.. turning the phone on loud and taking of any accessories gives the phone just enough vibration to make the mouse move across the top the phone !!!!!!!

The app does vibrate and the timer is nice but it doesn’t vibrate enough to move the mouse. My screen still locks, even when I enable high vibration. The app is useless to me so I’m uninstalling.
