Update: app cause my tablet yes tablet to lag. Causes my music player to crash consistently. Tablet works fine unless this app is installed. And before anyone including the devs haul off and say it must be my end. No sorry not the case I just as of today at 9:33am reinstalled this app after uninstalling on jan 8th and my tablet worked fine no lag, no app crashes. Serves a purpose, decent concept but needs more work. So I will use it but once I have real cameras I will not use it again!
