Custom QR Code Maker & Scan
Read full descriptionHide 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.

Verdict

MP3Converter's advantage is device support (3 vs 1) and iOS requirement (12.1 vs 17.0). On price and in-app purchases there is nothing between them.
