A reminder app, or better yet, a to-do list - a reminder of a check, a birthday, an occasion, designed for people who have a lot of tasks to do and forget about their work because of their busy schedule.
If you are a very busy person, using this program, you can record tasks and tasks by date and time and turn your mobile phone into a small digital assistant to notify you on time.

I hope you find the super simple but useful reminder useful.
