Not for memorizing!!

This is a great trainer for practicing; however, as a complete beginner, you can't learn the stack through comprehensive studying. The practice is meant for people who have already memorized the stack.

Response from developer

Thanks for the thoughtful feedback, that’s fair. Stack Trainer is currently strongest as a recall and practice trainer rather than a complete step-by-step stack course. Beginners can still start by using filters to practise a small group of cards at a time, along with PAO links and hints, then gradually expand from there. I’m also working on more dedicated learning features to make the first-time stack learning path clearer and more guided. I’ll also review the App Store wording so expectations are clearer. Thanks again for the useful feedback.

Absolutely love it!!!

Absolutely love this app, it is just what I needed to learn Mnemonica and then practice it daily!!!
Such a wonderfully made app.
Strengthen your recall with fun gamification.
