Version 1.9 is now available - this fixes an unfortunate bug in 1.8 that was causing crashes for some devices (either on startup, or switching camera).
One of the biggest problems in developing a camera application is that there are many different Android devices with different camera features and drivers, so sometimes crashes happen that don't occur on the devices I have access to (currently Galaxy Nexus and 2013 Nexus 7). If you experience a crash, this may be something I'm unaware of - the most helpful thing to do for me to fix the issue is to click the option to Report the crash, and let me know please (email, or on the forums, or open a ticket). Thanks!
