Used to work great on Marshmallow But I'm now on Android Nougat DP5 and the app keeps on crashing if you use the Camera2 API. It's a shame because that's why I use this app in the first place. EDIT: thanks for the reply  don't worry I'll wait for the update  and I increased my rating to support you. Are you working to implement camera2 completely? Because this is surprisingly the only good app to use it so I place a lot of expectations on it.
