I am looking to learn Mnemonica and I saw this app called "Master Any Stack" I think it's associated with or put out by The Daily Magician but I could be wrong. If anyone has used this app I'd really appreciate your honest thoughts. Also, if you haven't used it but have great things to say abut any other app to lean Mnemonica I'm open to hearing that.

Check out MemDeck Training.
Learn Mnemonica with a new card every other day (or so) in your email. Steady, regular progression to provide the most successful learning experience.
You can even preview it for FREE.

I used Stack master on the appstore at the time, multiple modes, interactive, nice !
Or Master any stack.
Or a printed mnemonica sheet from google image

Thanks for your responses!
