Timelapse Helper vs KeeperSafe

The Timelapse Helper is a neat companion for anyone interested in timelapse photography. It's a simple app to help you calculate the shooting time needed to create timelapse footage of a desired playback duration.

Back up your SD card without a computer. Plug a card reader into your iPhone or iPad, choose where the files should go, and KeeperSafe copies everything over. Each file is checked after it's copied, so you know the backup is good before you format the card. WHY PHOTOGRAPHERS USE IT The best photos happen furthest from a computer. On a trail, on a boat, in the rain. Your phone is already there. KeeperSafe gets your files off the card and onto your device while you're still shooting. WHAT IT DOES • Works with any SD or CFexpress card, through any iOS-compatible reader • Backs up to your iPhone or iPad, or to an external SSD or hard drive • Checks every file after copying. A bad copy never counts as done. • Shows progress on the Lock Screen so you can keep shooting • Keeps working in the background and resumes if the cable slips or the battery dies • Never re-copies files that are already backed up NO CHANGES TO YOUR FILES No compression, no conversion, no edits. RAW, JPEG, HEIF, ProRes, H.264, H.265, any format your camera writes, at any file size. The backup is byte-for-byte identical to the original, EXIF and all. PRIVATE There is no account to create and no cloud behind the app. KeeperSafe makes zero network requests. Your files move between your card and your storage and nowhere else. The App Store privacy label is "Data Not Collected."
