Getting stuck is the tiring part of a jigsaw. Hunting for one piece across a 1000-piece picture takes minutes — and the piece usually isn't where you're looking. PuzzleLens shortens that. You scan the puzzle's picture once, then photograph whatever piece you're stuck on, and the app tells you where it goes. **As much hint as you want, as little as you want** You don't have to see the answer straight away. Ask for the region first, narrow it down, and only then ask for the exact cell and which way the piece turns. How much help you take is your choice — and how many hints a puzzle took is kept in your records. **It says so when it isn't sure** Sky, water, flat colour areas… some pieces genuinely can't be told apart on their own. Rather than inventing an answer, PuzzleLens shows you a region and says it isn't sure. You learn which areas will be hard while you're still setting the puzzle up. **Everything on your device** Piece recognition runs entirely on your iPhone. No internet needed, and your photos don't go anywhere. **Your puzzle gallery** In progress, finished, set aside. Every puzzle gets a progress mosaic: placed pieces in colour, the rest dimmed. One picture that tells you where you left off. **With friends** Sign in if you want, add friends and share your progress. No account is needed to solve puzzles — the social side is entirely optional and free. **Your way** Light or dark theme, English or Turkish — all switchable inside the app, instantly. **Free, or go Pro** Unlimited puzzles, scans and hints — no daily limit. The app is supported by ads shown after scans. PuzzleLens Pro removes ads entirely. Pro is a monthly auto-renewing subscription; the price is shown in the app and on the App Store. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage and cancel it in your App Store account settings.

Verdict
The clearest difference is ads: Projection Mapping Toolbox at none against PuzzleLens's shown. Projection Mapping Toolbox also leads on device support (3 vs 1) and iOS requirement (14.0 vs 18.0). PuzzleLens's advantage is update cadence (every 8 days vs every 3 weeks). On price and in-app purchases there is nothing between them.
