Hourglass Timer is a free timer app for Android developed by Yuka Applications. As the name suggests, it features a beautiful hourglass design that makes it stand out from other timer apps. The app offers five different types of hourglass timers with durations of 1, 3, and 5 minutes, each with its own unique sand color.

In addition to the elegant design, Hourglass Timer also includes useful features such as alarm and vibration settings. These features can be customized to your liking for a more personalized experience. However, it's worth noting that the app is not gravity sensitive, so you can't flip your phone to turn the hourglass over.

One downside to this app is that on some devices, the sand falling animation may be slow. Additionally, if the app is interrupted by other applications, the timer will be canceled. Overall, Hourglass Timer is a simple and beautiful app that does what it promises.
