Never lose a shoot. Sync Shutter backs up your camera card the moment you insert it. Set it up once on your Mac, then plug in any card and walk away: every photo and video is copied to every destination you chose, automatically. On iPhone or iPad, plug in a card reader and import straight from the card. It was built for photographers who come home with several cards and cannot afford to lose one. WHAT HAPPENS WHEN YOU INSERT A CARD • The card is detected and the backup starts on its own. Progress lives in the menu bar; a notification tells you when it is done. • Only new files are copied. Already-backed-up shots are recognized and skipped, so the second run after a shoot takes seconds. • Copies to a folder or drive can be verified byte for byte after copying. • Files can be sorted into date folders taken from the photo's own capture date. • Cards that do not use a DCIM folder — video-first layouts from Sony, Panasonic and Canon bodies — are recognized too, and any card can be copied whole from the menu bar. • No internet where you're shooting? The card is still safe. Sync Shutter keeps its own copy and sends it to your cloud destinations on its own the moment you are back online. • A backup that cannot reach one of your destinations says so and names it. It never calls itself complete when something is missing. WHERE THE FILES GO Send one card to several places at once: a local folder or external drive, iCloud Drive, Google Drive, OneDrive, Dropbox, Google Photos, the Lightroom auto-import folder, or the Photos library. Turn on as many as you like; each card is copied to all of them in a single pass. CHOOSE WHAT COMES OFF THE CARD Turn on a review step and a grid of thumbnails appears before anything is copied, so you can leave the test frames behind. SYNC SHUTTER PRO — ONE PURCHASE FOR MAC, IPHONE AND IPAD • Back up to a NAS or server: any S3-compatible storage (Synology, Backblaze B2, MinIO, Amazon S3), or SFTP over SSH. • Cold storage: Amazon S3 Glacier and Deep Archive storage classes, chosen per destination, for an archive that costs cents a month. • RAW+JPEG pairs: keep both, RAW only, or JPEG only. • Import date filters: only today's shoot, the last few days, or everything since a date. • Custom file naming from the capture date, a counter and the original name. • Per-card rules on the Mac: route each card to its own destinations. • Auto-delete from the card after every destination has confirmed the copy, and low-storage alerts before a backup would fill the disk. Pro is a single purchase, not a subscription. IPHONE AND IPAD Plug in a USB-C or Lightning card reader, open Sync Shutter, and pick the card. Photos go to your Photos library, a folder in Files, your cloud drives, or an S3 NAS. A Live Activity follows the import and a widget shows your totals. PRIVATE BY DESIGN No account, no sign-up, no servers of ours in the path. Files go straight from the card to the destinations you chose. The only thing the app ever sends home is an anonymous count of backups and errors, so that problems get fixed; it is never linked to you. Works with any card your Mac or card reader can mount: SD, microSD, CFexpress, CFast, XQD.

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.
