Why I made this app
I noticed that rolling secret rolls during game was a bit of a hassle. Rolling dice multiple times, or multiple at once and then sorting them out. As well as four times the math was slowing down the game. As well as a bunch of dice rolling isn't exactly secret anymore.
So with this app, you just do a bit of prep work (inserting numbers for each player) and then you just roll with a click of a button and everything comes out neat. You can even set the DC and see what the outcome (succes, critical success, failure, critical failure) is.
