LongShot

LongShot stitches overlapping screenshots into one long image on iPhone. After one-time setup of the Shortcut, Photos access and Back Tap, double-tap to stitch supported small batches to Photos without opening LongShot. Larger batches or errors may need the app. Overlap is verified before merging. Screenshot processing stays on-device: no image uploads, no account, no ads. Up to 100 screenshots in-app, subject to device limits. 10 free stitches per month, with an optional one-time lifetime unlock for unlimited exports. No subscription.
