GPS coordinates are automatically embedded in every photo, making it easy to revisit both the images and the journey behind them years later. Turn on the camera and you're connected. No need to take your phone out or relaunch the app. Location data updates as you move, or when you press the shutter.

The 'Add Only' permission ensures the app only writes to your library without reading your existing photos.
