App is effective at draining battery, but the UI gets frozen so you can't monitor status easily, and ads are borderline abusive when exiting the app.

It's too slow because it only uses flash and vibration - it would be faster if it uses GPUnd CPU as well. Good thing it's shows the battery temperature and voltage,+ amperage .
