SW Maps vs TightScan

SW Maps is a free GIS and mobile mapping app for collecting, presenting and sharing geographic information. Whether you are conducting a full scale GNSS survey with high precision instruments, need to collect large amount of location based data using nothing but your phone, or just need to view a few shapefiles with labels over a background map on the go, SW Maps has it all covered. Record points, lines, polygons and even photos and have them displayed over your choice of background map, and attach custom attribute data to any feature. Attribute types include text, numbers, an option from a predefined set of choices, photos, audio clips and videos. Conduct high accuracy GPS surveys using external RTK capable receivers over Bluetooth LE. Draw features on the map by adding markers, and measure distance and area. Reuse the layers and attributes of a previous project for another survey, or create templates and share them with other users. Share the collected data with other users as Geopackages, KMZ or shapefiles, or export them to your device storage. Also share and export recorded data as Spreadsheets or CSV files.

TightScan is a document scanner built around one number: the size of the PDF you send. Most scanner apps produce 2–5 MB for a single page. TightScan produces the same crisp, scanner-quality page at 35 to 400 KB — and shows you that size before you export, so what you attach is never a surprise. FOUR PRESETS, FOUR REAL SIZES • Email-safe — ~35 KB per page, black & white. Forms and quick sends. • Text — ~50 KB per page, black & white. Crisp documents, minimal size. • Document — ~150 KB per page, color. The default: keeps stamps, signatures and highlights. • Photo — ~400 KB per page, color. When detail is the point. HOW IT SCANS Point the camera at any page. TightScan finds the edges, straightens the page, corrects the lighting channel by channel so white paper comes out white even under warm indoor light, and keeps the color where it matters. Add as many pages as you need, reorder them, export one PDF. NOTHING LEAVES YOUR PHONE All processing happens on the device. No account, no cloud upload, no analytics, no ads, no tracking — and the app works with no network connection at all. Your documents are yours. EXPORT ANYWHERE Share to any app, save to Files, or print with AirPrint. Standard PDFs that open everywhere. FREE AND PRO Free: unlimited scans, all presets, unlimited pages. Free PDFs carry one small "Made with TightScan" line on the last page. TightScan Pro — one purchase, not a subscription — removes it for good. No subscriptions. No ads. No accounts. No data collected. Just tight scans.
