I use it to record my stretching. I do several types of stretches for about 5 to 10 minutes depending on how I feel at that time, and I’m very satisfied with the simple feature that allows me to organize items by tabs and just put a checkmark on the calendar for each day.

おおぐらら

It’s really great! It’s easy to use, and you can change the check icons, which is cool. Thanks to this app, my motivation is boosted!

あつざえ

I thought it would be even more convenient if I could add a home screen widget so I could record without opening the app every day! Even in its current state, it’s very easy to use!
