I am looking for a break reminder app for Win10 that has the following features:

1. Auto start the timer when begin using the PC, or, an easy to press start button in the taskbar that directly starts and stops it with no other actions required.
2. Auto stop the timer after a defined period of time.

That's it.

I have looked through "the internet" and I don't have time to click down into each and every app webpage to find out if they have these features, and all of the "review" sites don't actually list and compare any features its all meaningless blather. Can you please help.
