Not bad, buy the extra features – Game Master 3.5 Edition Review

In general, the app offers bare basics for quick reference. Scry Free was only slightly better, because it's free version also came with class tables. $2.99 isn't bad for what you would get, but the lack of info on iconic monsters, like the beholder, keep the price from seeming completely fair.
