Why build another PDF utility?
Built around a shared C++17 image and compression core with native SwiftUI and Jetpack Compose apps.
Anyone who has had to submit paperwork before a deadline knows the annoyance: you open a scanner app to photograph two sides of an ID or a signed form, and the first thing on screen is a login prompt. Skip past it and you get a three-day trial that rolls into a steep weekly charge, or an exported PDF with a watermark in the corner.
Modern phones already have more than enough speed to crop edges, clean up shadows, recognize text, and shrink images right on the spot. There is no technical reason a routine scan of your passport or bank statement needs to leave your phone for an external server.
Doxio was written to keep those chores simple and self-contained. The core engine runs in native C++ on your device, wrapped in a quiet black-and-white interface that gets you in, finishes the file, and gets out of the way.
