Are you having trouble with the large size of the photos you take?
This app always shoots at Full HD (1920 x 1080) size, and keeps the size of each photo to 500KB to 1MB.
The following can be done in the options.
-Turn location recording on/off
When the icon is light, its off.
-Turn shooting at the same resolution as the Photos app on/off
When the icon is red, its on.
-Flash on/off
When the icon is red, its on.
Tap anywhere on the screen to lock the focus at that position.
When locked, a target icon will be displayed; tap this to unlock it.
