Напоминалка is a free Android app developed by Muzzon, designed to create reminders for daily events by creating text and setting specific times for notifications. It can also be used as an alarm clock. The app allows for an unlimited number of tasks to be created, and it notifies the user with a sound and a dynamic icon in the status bar at the set time.

In the settings, users can choose the duration of the sound signal between 3, 5, 10, 20, 30 seconds, or 1 minute, or choose a continuous signal. The app also features an autosave function that constantly saves the text of the reminders while editing. Additionally, there is a sorting function to keep the task list organized.
