STEP 03

Try it

  1. Keep your iPhone unlocked. Capture two or three consecutive screenshots with some shared content between them.
  2. Double-tap the back of your iPhone. Let the shortcut finish before tapping again.
  3. Open Photos and check the new long image, including each join. The original screenshots remain in your library.

Troubleshooting

The shortcut is missing from Back Tap

Open Shortcuts and confirm it is in your library. Check its saved name, then reopen Settings → Accessibility → Touch → Back Tap and scroll to the Shortcuts section.

Double-tapping does nothing

Run the shortcut directly in Shortcuts first. If that works, check the Double Tap assignment and try a deliberate double tap. If Back Tap is absent in Settings, check device support in Apple’s guide.

There is no long image in Photos

Open LongShot to check photo access and your remaining free allowance. Use a fresh pair with visible overlap from the same screen. Unrelated screenshots cannot be stitched reliably. Large batches may require continuing in the app.

Apple’s Back Tap guide ↗

Verified overlap, no ghosting. On-device, no ads, no account. 10 stitches a month free.
