SimpleThumbTimer

This app allows you to set the timer with one hand.
By default, you can set the default time every 1 second, 30 seconds, 1 minute, and 10 minutes.
The time is set when you touch and then move, and the title button appears when you touch and determines which theme you want to set the timer.
The second page shows timer records within 24 hours.
When the timer reaches zero seconds, a push notification will be issued. Also, at 0 seconds, the image on the second page is replaced with a confirmation image.
On the third page, you can set the title and show the version of the app.
So it's a very simple timer app.
