I switched to RPG Roller forever last week! I was able to enter custom formulas on the hot buttons page. I added in all of my skills, coloured the trained skills green, the rest gray, and the poor skills (swim, climb) light gray :). So I have a quick page with my weapon attacks, all my skills and my various weapon damage. I had forgotten to add 4d6 for a spell, and when the GM asked me to roll it, I just went to page 1 where all the dice combos are, and just pressed 4d6. Voila...no time lost!
It is amazing how much time I saved, just not having to reach for the dice pouch, single out the dice and roll them. I pressed my tumble button (d20+5), my Attack button (d20+4) and damage (4d6) in about 10 seconds. Left the rope on my dice bag knotted, and never had to look for a missing die.
About the app: had some trouble doing 2d8 + 1d6 - 1 but figured out if you space it as I just did, it works. I love having Attack, Attack +2 (charge/flanked) or Attack -2 buttons ready.
The app keeps track of your rolls. I just resolved a sequence of events by referencing what happened 2 nights ago. I hope that I can email the stats to myself, but I know there is a backup feature.
Feedback for Author: the Hot Buttons page is the key. If it could look any more professional (ie like Dice Ex dice sets page) I would pay for this app. Also, the F function is too bad. It would be nice if there was a way for the GM to check easily, because I dont want to use it, but I also dont want other players to use it :) so the game stays fair.
