QR Code Reader

01.

Intro of case

Scanning codes is now a part of everyday life — from checking product prices to unlocking Wi-Fi or grabbing quick discounts. We set out to create a fast, reliable, and feature-rich QR Code Reader & Barcode Scanner app that anyone could use with just one tap. Whether it was scanning product barcodes or generating custom QR codes, the app had to be simple, helpful, and lightning-fast.

Work challenges

The biggest challenge? Competing in one of the most saturated app categories in the store. QR scanner apps are everywhere, and many offer the same basic features. To break through the noise, we had to build an app that not only worked perfectly but also ranked well in stores and reached users who actually needed it. Balancing functionality with a lightweight design and finding the right audience through user acquisition was key.

Main result

With clean development, well-optimized metadata, and focused UA campaigns, the app crossed 1 million+ downloads in record time. We ranked for high-converting keywords like “free QR scanner”, “barcode reader”, and “QR code generator”, helping the app gain strong organic visibility. Our campaigns drove targeted installs at a cost-efficient rate, while app store ratings and retention confirmed one thing: users found real value in the app’s simplicity and speed.
