Hours Minutes Calculator is a simple and free Android app developed by Evans Mauta II. It is designed to help you add and subtract times in HH:mm format without having to convert them into decimal numbers. With this app, you can easily calculate the duration between two time periods, making it a useful tool for anyone who needs to keep track of time accurately.

The app comes with a Light and Dark theme, giving you the freedom to choose the one that suits your preferences. The interface is straightforward and easy to use, making it ideal for people who are not tech-savvy. Overall, Hours Minutes Calculator is an excellent utility app that does what it claims to do without any fuss. However, it lacks advanced features that other time calculator apps offer, making it more suitable for basic time calculations.
