Custom QR Code Maker & Scan

Features
Read full description

Design a QR code people actually want to scan — and one that always scans. Most QR apps hand you a black square. QR Studio lets you shape it, colour it, drop your logo in the middle and set it into an illustrated poster — then checks, every time, that it still reads. DESIGN IT PROPERLY • 18 illustrated scenes: sticky note, price tag, ticket, neon, business card, event poster and more • 13 dot shapes and 5 finder shapes, gradients, and a separate colour for the corners • Colour the dots from one of your own photos — the picture is darkened just enough that the code still reads • Or pick a GIF or a video and the whole code moves — every frame is darkened the same way a still photo is, so every one of them still scans, and it shares as a looping GIF • Your own logo in the middle — error correction is raised automatically to make room • 14 frames and 5 caption fonts, or write your own line of text ALWAYS SCANNABLE • Live contrast check as you design, with a plain verdict: good, risky, or won't scan • A design that would fail cannot be saved — one tap repairs the colours and keeps the rest • Decoration is drawn around the code, never over it TWELVE KINDS OF CODE Link · Social profile · Wi-Fi · Contact card · Email · Phone · SMS · WhatsApp · Location · Calendar event · Payment link · Plain text SCAN, TOO • Read any QR code with the camera, or from a photo you already have • Nothing opens on its own — you see the exact contents first, every time • Scan history stays on your device and is never uploaded YOURS, AND OFFLINE • No account, no sign-up, no server • Your codes sync through your own iCloud, or stay on one device • Every code is static: it carries its own content, so it keeps working forever — even if this app disappears QR Studio Pro unlocks every illustrated scene, every frame and shape, gradients, custom colours and your own logo in the middle.
