Is there a good application for windows: a clock that will be on top of all windows and will display alerts at specified time intervals?

Question

Windows

Hello.
Please advise a good application for windows: a clock that will be on top of all windows and will display alerts at specified time intervals?
IMPORTANT : you need the application to start when you turn on the computer (autostart).
I already have one such application and it can be set to autorun. BUT each time you have to open the application menu and configure it to be on top of all windows and re-set notification intervals. Notifications are set by the user himself: for example, display the text "look out the window" every 20 minutes.
I'm sure there are such programs. It's really hard to find a good one.

Answer 1

Writing this, I think, is absolutely not difficult.
Yes, and what is difficult? Take time from the system? Take him out? Make notifications? Save settings?

Answer 2

You can create tasks in outlook, and Venda is synchronized with the calendar and notifies like this
By the way, when the screen is locked, it also displays notifications. Convenient, but you have to switch to microsoft

Answer 3

I was looking for a similar application myself, I did not find it. I wrote my own, I use it every day.
Fully automated, no need to remember to remember to start the timer again. Time intervals are flexibly configured.
