Your photos capture not only the moment, but also where it happened. 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. Exporting is just as simple: swipe to select multiple photos and save them to your photo library with a tap. JPG and RAW files are grouped together automatically, keeping your library organized. The 'Add Only' permission ensures the app only writes to your library without reading your existing photos. Compatible cameras GR IV series · GR III series *This app is NOT associated with the Ricoh Corporation*
