Pendulum Clock - Chime Live, developed by Dev Technosoft, is a free lifestyle app available on Android. This app offers a variety of options to play sounds and speak time every quarter to half and full hour. It plays a Westminster chime each quarter-hour and provides a realistic live wallpaper.

The app has many inbuilt clock chimes and allows the user to choose a custom chime from their device. It plays quarter, half, and full hour and speaks time with a custom title. The app also has an hours-only option and wakes the screen to stop. In addition, it can be stopped from the notification bar. However, it should be noted that this app works in the background, so some devices (running MIUI & Honor, etc.) may need to be kept in auto-start or locked in the recent menu.

Overall, Pendulum Clock - Chime Live is a useful app for those who want to keep track of time and enjoy the sound of a Westminster chime. The app is easy to use and provides a variety of options to customize the chime sound and wallpaper.
