LongStitch vs ScanFix

How do you create a long screenshot from a screen recording video? LongStitch is the only app that imports your screen recording directly and stitches it into one seamless scrolling screenshot — no re-recording required. THREE THINGS NO OTHER APP DOES AS WELL: 1. VIDEO TO LONG SCREENSHOT Import any screen recording video from your camera roll. LongStitch extracts and aligns the frames automatically, producing a single long image with clean, pixel-perfect seams. No other app focuses on this workflow. 2. SCROLLBAR REMOVER Scrollbars ruin long screenshots. LongStitch detects and removes them automatically. The result looks clean and professional — exactly what you'd want to share or archive. 3. 100% ON-DEVICE. TOTALLY PRIVATE. Every frame is processed on your iPhone. No photos or videos are sent to any server. No account required. Works offline. Your data stays yours.
