This app is pretty good

It looks like its trying to copy an old app called "iKarmasutra" its pretty good, but definitely needs more positions (possibly iap), and a better UI for when one of the "todo/tried/fav" options are selected. Its probably the best app for this sorta thing though, since ikarmasutra has been removed from the App Store...
