App Description

[Attending school, commuting must-have app! ! ][For a limited time only]
This is the best silence timer to prevent riding-past of bus and train.

It will awaken you with powerful vibration when time has come.

You can set an alarm on three stages. Silent, Normal, and Powerful.

Silent ... At regular intervals. Longer interval.
Normal ... At regular intervals. Shorter interval.
Powerful ... MAXIMUM.

To prevent accidentally timer cancel, it is equipped with a software lock function.
Also during using the software lock function, you can check timer working.
So you can feel safe.

I recommend for people who want to take advantage of time commuting or during commute !!
