Yup, that one thing we've been clamoring for has come to pass: the FFG dice app now has an option in settings that will have it cancel out matching results (success and failure cancel, etc) and give you the "net roll". There's no animation or anything fancy. Just roll the dice like usual and the results at the bottom are the net result. If you want the "gross result" or raw data, you'll have to read the dice.
Fantastic addition to the app, especially making it an option for those who prefer to do their own interpretation.
Also - it works for X-Wing as well.
