FlashQR reads every common barcode format (QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code128/39/93, Codabar, ITF) and builds QR codes for 19 use cases — Wi-Fi, vCard, UPI payments, WhatsApp, calendar events, coupons, and more — with real forms instead of hand-typed payload strings. Customize with colors, shapes, and a logo. Everything is stored locally and encrypted, with a searchable, exportable history. No ads, no account, no paywall, and the app makes zero network requests of its own.
