So far very nice. I also like that the practice is broken down to its components too, good idea

Obviously layout, no ads, free. What's not to love?

This is outstanding minus some quirky behavior. Occasionally the explanation is just wrong. January never has 32 days. (Dev: I have a screenshot of your want it.) UPDATE: My ignorance. Thank you for the response. Second, the training automatically advances when you score high enough. It's simply too aggressive. More time at a lower level would be helpful without exiting and resetting. Despite those flaws, this is really good, especially for such a niche skill.

Great for daily practice. Slowly getting better! Would love to see a progress graph of best daily time Vs days training

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.
