Brightest Timer

This is a timer app that automatically adjusts the brightness to the maximum.
When you close the app, the brightness returns to its original value.

When using other timer apps, I maximize brightness,
and ,after using it, I should return to the original brightness EVERY TIME!
It's troublesome!
So, I made this.
From now on, I do not need to change brightness when using the timer!

With landscape display, the characters get bigger and easier to see.
