I Built a 100% Free Document Scanner App — No Ads, No Watermarks

Why I Built SmartScan Every document scanner app I've tried is the same: ads everywhere, watermarks on every page, and a paywall hiding basic features. So I built my own. What It Does SmartScan is a completely free Android app that lets you: Scan documents to PDF — Fast edge detection, multi-page support QR Code Generator & Scanner — Create and scan QR codes instantly OCR Text Recognition — Extract text from images Edit & Sign Documents — Add signatures, annotations Share anywhere — Export as PDF or image What Makes It Different 100% free Zero ads No watermarks No account required Open source (Kotlin/Android) Tech Stack Built natively with Kotlin for Android.
