Scan Em Up turns your iPhone into a pocket scanner that produces clean, sharp PDFs in seconds. Built for people who scan real paperwork — receipts, contracts, medical forms, IDs — and want results that actually look scanned. KEY FEATURES • Smart edge detection Camera highlights the page in real time and snaps once it's framed. Perspective is automatically straightened, so even handheld shots come out aligned. • Multi-page in one go Capture as many pages as you need without leaving the camera. Continue, retake, or finish whenever you're done. • Document-grade enhancement Per-image white-point correction makes paper look truly white. High-contrast text stays crisp even at the strongest compression — no muddy gray scans. • On-demand PDF compression Four quality levels — Original, Light, Medium, Strong — let you trade size for fidelity. Strong typically reduces file size by 70% with no readable difference. • Edit any page Rotate, auto-upright (Vision-based), perspective crop, reorder, duplicate, copy/paste between documents. • Sign with your finger Draw signatures with finger or Apple Pencil, or import a saved one. Place anywhere on the page, resize freely, then bake into the PDF. • Privacy first Everything stays on device. No accounts, no uploads, no tracking. Raw scans live in app storage and are kept untouched even when you export. • One-time purchase The free plan keeps a single document. Unlock the full app once and scan unlimited documents forever — no subscriptions. WHO IT'S FOR — Sailors, drivers and freelancers who deal with paper contracts on the go — Students who need fast, legible PDFs of handouts and notes — Anyone tired of scanner apps that demand subscriptions for basic features
