This is a great tool for Puzzle and Dragons - it can help you make some nice combos... If you dont need to match rows or TPAs, and if there are no poison orbs on the board.
Several issues with this app:
1) no poison orb support
2) no enhanced heal orb support - a big problem for teams that already enhance heal orbs and an even bigger problem when the heal orb awakenings come to NA
3) hideous interface (and tons of ads, though can be IAPd away)
4) any special algorithms (TPAs, color specific matches, multiple rows) require IAP
5) that would be okay, but each algorithm requires a separate purchase, PER COLOR - if you were to buy every feature, it would cost you $22
The IAP model for this app makes no sense as is. The app would make more profits if the model were changed to a one time purchase. Furthermore, the bugs abound make this app a nuisance to use at best, and unusable at worst. Unless this app is fixed, as soon as a better App Store alternative comes, this is dropping to one star.
EDIT: Also, the claims made in the images are BS.
