GRPS makes it easy to automatically start and stop location sync from your iPhone to your Ricoh GR III and GR IV cameras. Once the initial connection is made, the app will automatically wake up and start syncing whenever your camera is powered on with Bluetooth enabled within range of the iPhone – even in the background! This allows you to reliably get up to date location information in your images without having to interact with an app, set an explicit duration for location updates or excessively drain your iPhone battery. Basically, set it up once, then forget about it. GRPS also allows you to easily sync your photos to your phone library.
