STimer- Simple and Disappear-

< simple layout>

When pressing a green button, a timer starts.

When a green button is pressed once again, it stops at 1:00.

When a red button is pressed, it's possible to return it to 00:00.

< a screen doesn't go off.>

As far as it's a battery while an application has been started, a screen keeps lighting up.

Though I was planning for time, they don't become selfish in the sleep state!

Please use it for practice of presentation by all means.

< improvement points and moot point>

If there are improvement points, a moot point and a bug, it's trouble, but it's as far as I'm happy when you can report it from a review.

Please take care of the "S series" you tend to use simply.
