Good effort that could be made perfect!
This application is good overall but in my limited review I found atleast one error in the listing for avarohanam of Melakartha 6: Tanaroopi. It is listed as S' R1 G1 M1 P D3 N3 S instead of the correct one which is S' N3 D3 P M1 G1 R1 S. Also, a few popular raagams like Janaranjini, saraswathi, Karnaranjini are not listed. Granted the user can add them but it will be nice if the next version of the app is released soon correcting the error and expanding the database of raagams. In spite of these minor points, it is a very good effort by the author and is definitely worth the price for a carnatic music lover.
