Give your mind some breathing room. This simple and minimal app holds the non-urgent tasks that weigh on you, the things without pressure or a defined time frame. Instead of burying them in busy to-do lists or forcing them onto your calendar, keep them in a dedicated, uncluttered space. Some of these tasks don't need a date β they need your full attention, just once. Lock in, and the task takes over your screen with a timer running. Even in Focus mode or silent, an alarm breaks through the moment time's up, so you actually come back to it. When the moment comes and a task deserves a date, simply send it directly to your calendar from within the app. One smooth action. To keep these tasks visible without opening the app, use the home screen widget, designed for gentle awareness rather than pressure. It surfaces the tasks you want to keep in mind, helping you stay connected to what matters without crowding your day.
