A free app for Android, by ZipoApps.
The app’s main advantage is that you can add sound messages to your alarms, so it seems like your alarm clock is speaking to you. For example, if you set “Ugly Ugly Frog” as a sound message, every time you’re going to wake up, you’ll hear the phrase “Ugly Ugly Frog”.
This app is also developed to use very low system resources and offers versatility since you can use it as a clock manager or as a desk clock as you charge your device.
What’s more, the time is displayed in large and noticeable numbers to make it easier to right regardless of the light setting and distance. It also works even when your screen is off, in silent mode, or when earplugs are plugged in.
The app even comes with a built-in nightstand digital clock, which automatically displays the current time and battery status of your device as you charge it.
