5 stars: 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 thats a small gripe and doesn't effect the usefulness of the app, it's otherwise great.
5 stars: So far, this is the best app I've found to train and practice the \
5 stars: Great app for practicing and even learning. I went from barely knowing how the algorithm works to being able to do it with any date in a matter of days.
5 stars: 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.
5 stars: Great for daily practice. Slowly getting better! Would love to see a progress graph of best daily time Vs days training
5 stars: Just what you need to practise your day of week algorithm, whether it's the Doomsday one or some other one. Good timing tests and stats. Great practice!
4 stars: Can you please provide a way to reset levels or go back to a slower speed for review? Thank you so much for this app. I've been putting off properly mastering the doomsday algorithm for years so this is just what I've been waiting for!
3 stars: Generally great, but base camp button takes me to training fields so I can't get the information required for some training exercises.
5 stars: I already have 264,366coins! I'm #1 wordwide at this app! Best app of its kind on t...
