Bowline pulls photos off your Ricoh GR, geotags them automatically, and saves them to Apple Photos. Everything happens on your device. No account, no analytics, and your data stays yours. The GR III has no built-in GPS. Bowline fixes that without changing how you shoot. SHOOT LIKE YOU ALWAYS DO Pair once and Bowline stays quietly connected while you shoot. Live battery, storage, and camera status on your phone, and a remote shutter when you want it. No fiddling between shots. EVERY SHOT, GEOTAGGED Your photos are geotagged on your phone. While your GR is with you, Bowline keeps a private log of where you are and matches each shot to the place you took it, by capture time. SCAN ONCE, DECIDE ANYWHERE Import everything in one touch, or scan the card and take your time. Swipe through what's new and keep or reject each shot with the camera off and back in your bag. JPEG or DNG, your keepers land exactly as shot, in a dedicated Bowline album in Apple Photos. Once every shot is decided, Bowline tells you the card is safe to format. YOUR FILES, UNTOUCHED The originals on your camera are never modified. Bowline imports clean geotagged copies and leaves the card exactly as it found it. BATTERY THAT GOES THE DISTANCE Sync is a short burst you choose to run, so the camera's battery lasts. No silent background transfers, no surprise drain. PRIVATE BY DESIGN No account, no login, no analytics, no third-party data sharing. Your photos and your location are processed on your device and stay under your control. SUPPORTED CAMERAS Built for the Ricoh GR III and GR IV, including all their variants. You will need a Ricoh GR camera to use Bowline. It does not work with other brands. WHY BOWLINE Bowline was built by a GR owner who wanted one focused tool: photos off the camera, tied to the places they were taken, into Apple Photos. Every shot, tied to its place.
