It's still possible to have an app crashed on few devices even if it works on some, that's not a valid argument. I am sure if original is not crashing on your end, mod will not too but I don't mod apps that I can't test on my end. If next version too crashes on my end, I'll contact developers but till then I'll wait

Sorry but which phone do you have bro?

Please, update to latest version, a lot of work has been done in it, now it's not so slow app.
