The mobile application "Time Since" is designed for habit monitoring using timers to track the duration of habit maintenance. Available on major app stores, the app follows a freemium model that provides a limited free version and a pro version with additional features. Over the past year, the app has generated over 10,000 euros, primarily through in-app purchases on Google and Apple, billing users monthly. Developed using React Native, the app benefits from extensive community support, making future development straightforward. Despite not releasing updates since its 2021 launch, "Time Since" continues to earn nearly 1,000 euros monthly, due to organic sales and minimal maintenance. The app is highly popular, with over 100,000 downloads and a 4.5-star rating on Google Play. Users frequently send emails with suggestions and requests, indicating potential growth through active development. The current owners, a software consultancy, have been unable to focus on the app due to other commitments. As a result, they are looking to sell the app, which still generates consistent monthly revenue without additional input. For potential buyers, transferring the app to a new account requires a developer's license and continued reputation maintenance on app stores. While technical advice for maintenance is recommended, the app can continue to generate revenue without immediate updates. The majority of its user base is located in the USA, UK, Canada, and Germany, all acquired organically.
