I used to GM PbP games for friends on a forum that doesn't have dice-rolling capability. I used an app where I could choose the number of sides of the die and how many of that die were rolled with the push of a button. I could also build macros for commonly rolled things like initiative and complicated attacks with lots of bonuses/penalties that I didn't want to look up every time.
Sadly, the developer stopped updating the app and it stopped working with a recent iOS upgrade. Does anybody have any recommendations for apps like what I've described above?
I use iOS, but recommendations for other mobile operating systems are also welcome. I guess websites that do the same would be acceptable, but I'd prefer an app that doesn't rely on the internet to work when I need it to.
