Link to the app's page on the Play Store (IMPORTANT: "Visit website" button on this page is "broken" because SideProjectors adds a utm-source tag to the URL that makes it invalid. Please access it through the link above. Sorry for the inconvenience 😅) The Coins & Notes Counter was one of my first side projects. It is a personal finance Android app. With over ⭐ 690 reviews on the Play Store and recurring revenue, I'm very proud to let someone else take care of it now. 🤓 How does it work It's an Android native app made with Java and SQLite database. Everything is processed and saved locally on the user's phones, with no API or server to host/run. In the app, users can: Count how many notes and coins they have (whether it's USD, EUR, or BRL) Save and visualize their records Protect the app with a PIN password 🌐 Web app I've also developed a simple web app with React that replicates the basic functionality of the mobile app (counting money, in this case, BRL – Brazilian Real). It's included in the package and you can see it working here: https://contadormoedasenotas.com The domain is the only expense I have, and it's equivalent to something like $0.83/m on Google Domains (in Brazil). 📈 How I've been monetizing it I've been generating recurring revenue for almost 3 years now, which demonstrates the app is relevant and there's also room to grow it even further. The main form of monetization I've used is through AdMob's ads. It's easy to set up and receive payments. There's also a one-time in-app purchase for users to remove ads if they want to.
