Sometimes you need to set a reminder QUICKLY AND SIMPLY. With minimal steps. Just the text (sometimes without it) and the time. And when the reminder comes, it's just as easy to complete or postpone the task for 15 minutes, an hour, or until tomorrow... Sometimes it seems like that's all you need almost always. Quickly and conveniently set one-time reminders and don't forget about recurring tasks (drink water, exercise, healthy habits, medication). Set your favorite reminders for quick entry with one tap (boil an egg, run a bath, etc.). The first app where entering a reminder requires no text at all. Funny emojis will automatically appear at the right time. (Text and notes for reminders are included, of course, for those who are not lazy.) A sound library and 2 volume levels: loud - for everyone around, quiet - for introverts with a poor memory (like me))). Plus a secret "silent" option, just vibration—just as you requested, James. Advanced features: additional reminder repetitions, reminders with images, a large widget with a reminder list, a countdown widget, and more.
