Rewind° vs PersCrop

Remember when taking a photo meant something? REWIND is a social camera app built around the magic of the unexpected. Take up to 10 shots a day with no previews, no filters, and no retakes. The moment you press the shutter, your photo disappears into a darkroom. You won't see it until the next morning at 9AM — when everything develops all at once. That moment of anticipation is the point. SHOOT FREELY No preview means no anxiety. No filters means no performance. You shoot what's in front of you, exactly as it is. The imperfection is the aesthetic. REWIND applies a subtle analog film effect to every photo automatically — giving your shots the warmth and texture of real film, without the hassle. DEVELOP AT 9AM Every morning at 9AM, your darkroom opens. All your photos from the day before reveal themselves at once — yours and your friends'. It becomes a ritual. Something to look forward to when you wake up. A daily surprise that makes ordinary moments feel worth capturing. SHOOT WITH FRIENDS Create private group darkrooms with the people you actually want to share your life with. Everyone shoots throughout the day, and when the time comes, you all reveal together. The suspense is shared. The reaction is real. No public feed, no strangers, no algorithm — just your closest circle. COMPETE IN CHALLENGES Daily, weekly, monthly and yearly challenges give you a reason to see the world differently. Saturday night. Golden hour. Strangers. Seasons. Each challenge is a prompt — a creative constraint that turns an ordinary moment into something worth shooting. Compete with friends in private group challenges, vote for your favourite shot, and see who wins. BUILD YOUR ARCHIVE Every photo you save becomes part of your visual diary. Browse your archive by date, revisit what you were doing three months ago, a year ago. REWIND is not just a camera — it's a memory. A record of your life told one shot at a time, in the order it actually happened. YOUR PHOTOS, YOUR RULES REWIND is invite-only. No public profiles, no follower counts, no explore page. You choose who sees your photos. You choose who's in your groups. The social graph is built on real relationships, not random connections. Your photos are stored securely and never used for advertising. We don't sell your data. We don't show you ads. REWIND is a space to shoot freely — and that freedom starts with your privacy.

PersCrop flattens a photo shot at an angle into a straight-on rectangle. Drag the four corners onto your subject and the photo is warped square using a true projective transform — the same maths a scanner's dewarp uses — not a rotation or a stretch. Everything runs on your phone; no photo ever leaves the device. Photograph a whiteboard, a page, a painting or a shop sign and the angle you stood at is baked in: edges lean, corners stretch, the rectangle isn't a rectangle. That is the problem PersCrop was built to solve. Around it sits a small set of tools for the rest of what you do to a photo before posting it. PERSPECTIVE CROP — straighten a photo taken at an angle • Drag four corners onto any four-sided subject: documents, whiteboards, artwork, posters, shop signs • A real homography warp removes the keystone distortion and returns a proper rectangle • Live preview updates as you drag, so you see the result before exporting • Output resolution follows the shape you selected, so detail is kept • Export as PNG, JPEG or WebP NO CROP — fit the whole photo to any aspect ratio • Post the entire photo, with nothing chopped off by a square or vertical frame • Pad to any ratio with a solid color, a gradient, or a blurred copy of the photo itself • Square 1:1, Portrait 4:5, Story 9:16, Classic 4:3, Wide 16:9, plus 3:2, 2:3, A4 paper, 21:9 cinema and 3:1 banner COLLAGE — several photos in one frame • Column, row, grid and diagonal layouts that adapt as photos are added or removed • Adjustable gaps, corner rounding and background color • Pinch and drag inside a cell to position each photo exactly PANORAMA CROP — one wide photo, one seamless carousel • Slice a wide shot into equal panels that line up as the carousel swipes • Choose the panel count and which part of the photo the panels cover GRID CROP — turn an image into a profile mosaic • Cut one image into tiles that rebuild it across your profile grid • Three tiles wide, as many rows as you want • Tiles export in posting order, so the mosaic assembles correctly BUILT FOR PHONES • GPU-accelerated rendering, so previews move with your finger instead of lagging behind it • Light and dark themes that follow your system setting • Save straight to your photo library, or share to any app • Batch save several results in one run PRIVATE BY DESIGN Every crop, warp and export happens on your device. PersCrop has no account, no sign-in, no analytics profile and no server to send photos to. Photo library access is used only to read the picture you pick and to save what you make. It works with no connection at all. WHAT PERSCROP IS NOT It is not a document scanner: there is no OCR, no text recognition and no multi-page PDF export. It straightens and exports images. PERSCROP PRO The core tools are free. Pro is a one-time purchase — no subscription and no recurring charge — and unlocks all tools, the full set of aspect ratios and editing options, and unlimited batch saving. Questions or feedback?
