App idea: A to-do app that hides your to-do list

I have an idea for a productivity app that I would genuinely use every day, but I haven’t been able to find anything like it. The main goal is to reduce the feeling of being overwhelmed by a huge to-do list. Instead of showing everything you need to do, the app only shows you one task at a time. Core idea - Create a shared to-do list (for yourself or with a partner). - Add as many tasks as you want, but keep the full list hidden by default. - The home screen has one simple button - The app randomly selects one task and shows only that task. - You can mark it as completed or ask for a different one. Time filter When adding a task, you estimate how long it takes (for example: 2, 5, 10, 15, 30, or 60 minutes). Before choosing a task, the app asks: “How much time do you have right now?” It then only suggests tasks that fit within that amount of time. Example: I have 10 minutes. The app only chooses tasks that take 10 minutes or less. Optional features - Shared lists for couples or families. - Choose between random selection or prioritizing older/high-priority tasks. - Filter by location (home, grocery store, outside, etc.). - Filter by energy level (low, medium, high). - “Not now” button that skips a task without deleting it. The idea is to remove the mental load of looking at a long list and deciding where to start. Instead, the app acts more like a personal assistant that simply says, “Here’s one thing you can do right now.” I don’t need anything from this idea—I just want an app like this to exist. If someone thinks this would make a fun project to build, I’d be the first person to download it.
