Alarm Clock is a free utility app developed by Krzysztof Kosmala that provides a reliable and straightforward way to set alarms on your Android device. This app has a clean and intuitive interface that allows you to set the time, choose the alarm sound, snooze length, and vibration options. You can also set the alarm to repeat daily, weekly, or on specific days of the week.

One of the app's best features is the alarm icon in the Android status bar, which makes it easy to see if you have an upcoming alarm. The main window can be displayed horizontally or vertically, and the app also allows you to store your settings for future use. Additionally, the app provides a notification message and alarm and snooze management directly from the notification level. The app is available in English as the default language, but it also supports Polish and other languages.

However, it is essential to note that using a boot manager may require additional permissions for the Alarm Clock app to function correctly. Moreover, using programs such as optimizer, memory accelerator, or other similar apps may result in the removal of alarms set by the Alarm Clock app.

Overall, Alarm Clock is a reliable and easy-to-use app that provides all the necessary features for setting alarms on your Android device.
