Started Find Boxes in 2024, it's a project and inventory management tool for audio visual companies. Took longer than expected to get the first customers, but I'm a bit above $300 a month now. I hope to cross the $500 a month mark sometime next year.

This app looks really cool. Did you developed also an ios app for it? It would be much easier to do all the task in an app.
