But often interruptions are inevitable - some short but urgent call, someone asks you something, etc - some actions that you have to react to. If you stop the work timer and start it over again, it'll break the smooth process. That's why we've added the 'Pause' function.
If you press the pause button during the work period, it will pause the timer for 1 minute so you finish with your interruption, then will return to the minutes remained in your work period. We think it will let you keep the idea in your brain that the work process is on, thus you don't switch the contexts and then have hard time to return back.
You can pause once only during a work period, and during a break period pausing seems not needed.
Also in the current update, as said before, trying some ads in the app, only on the one screen now. And some UI/UX changes.
