Incrementally back up your iPhone photos and files to external USB drives. No internet, no subscription, no compromise.
No cloud, no subscription, no file size limits. Just plug in your drive and go.
Writes directly to USB drives, SD cards, or external SSDs. Works without Wi-Fi, cellular, or any internet connection.
Only transfers new and changed files. Re-plug your drive weeks later and pick up right where you left off.
Photos, videos, and Live Photo .mov files are all preserved as a whole. HEIC, RAW, ProRes — everything.
Back up any folder exposed in the Files app — DJI footage, Procreate files, voice memos, anything.
4 MB chunked read/write keeps memory usage minimal. Safely handles 100 GB+ backups without crashing.
Zero analytics, zero tracking, zero data collection. Your photos never leave your device and your drive.
No account setup, no configuration wizard. Just the essentials.
Pick your Photo Library or a custom directory, then choose a destination folder on your external drive.
Connect your USB drive. AmberTime instantly scans for new files and shows you exactly what needs to sync.
One tap to start. Incremental diff means only new files are transferred. Unplug and go.
