if you like my open source apps such as open camera, please help support development by buying this donation app. please keep the donate app installed for at least 24 hours - otherwise google may do an automatic refund. the app itself doesn't do anything. donations can be used for: purchasing hardware for development/porting/testing; app store fees; beer/pizza money :) thanks! (note that vibrance hdr and hexabots are supported by ads, there's no need to donate for them.)
