Comments on Doomsday Algorithm Trainer for Android

★★★★★ I have used this app every day to practice the doomsday algorithm. It is great. I have noticed myself getting better just from the challenge of having to do it in a specified amount of time.

★★★★★ The perfect app for learning and practicing the Doomsday method. Incredibly useful. Seems to have an issue with daily streaks not registering on my device, but that's a small gripe and doesn't affect the usefulness of the app, it's otherwise great.
