Scan QR Code

A straightforward QR code scanning app that does exactly what its name promises — it reads QR codes quickly and reliably. Built by a solo developer as a bootstrapped side project, it demonstrates that simple utility tools can scale into significant businesses when the execution and distribution are done right. The app monetizes through a combination of subscriptions and in-app ads, generating approximately $1 million per month in revenue. Its success underscores the enduring demand for single-purpose apps that solve an everyday problem without unnecessary complexity.
