What 15|30 does

15|30 is a rewind camera. With the buffer armed, the last 15 or 30 seconds are always being recorded into memory. When something happens, tap once — the past is saved, and the camera keeps recording forward until you stop.

Quick tips

• Tap the power icon on the dock to arm / disarm the buffer.
• Tap 15s or 30s to choose how far back the buffer holds.
• Pinch to zoom, or tap one of the .5× 1× 1.5× 2× presets.
• Tap anywhere on the preview to focus.
• Tap the shutter once to save. Tap again to stop the forward recording and write the file to your Photos library.

Permissions

• Camera — required.
• Microphone — optional; deny it to record silent video.
• Photo library — Add only — required to save clips.

If you denied a permission earlier, you can turn it back on in Settings → 15|30 → Permissions.

15|30 Pro

Pro is a one-time purchase, not a subscription. It unlocks custom buffer lengths beyond 15s and 30s. Off, 15s and 30s stay free forever.

Restoring a purchase. If you reinstall the app or move to a new device, open the Pro screen and tap Restore Purchases. Your unlock is tied to your Apple ID, so it comes back at no cost. Make sure you are signed in with the same Apple ID used for the original purchase.

Refunds are handled by Apple, not by us — use reportaproblem.apple.com.

Diagnostics

From version 1.1.2 the app sends anonymous crash reports and usage counts so we can fix bugs. No personal data and no video ever leaves your device. You can switch this off in Settings → Diagnostics.
