Wish I'd known about this app years ago!
I go through my anki list each day while exercising. It just works great. I initially used it for language learning but now I just add everything in there I need to remember as a custom deck, birthdays, names etc. It's nice not to forget stuff. The iOS version syncs with the web and any other devices you have. It's powerful but most of the custom settings I don't need. You can export / import your data, and there are decks available online for various subjects. I'm glad I can support the developer.
