There are plenty of apps for habit tracking and schedule management, yet sticking to them is always a challenge. You write down your plans, feel satisfied, and then end up structuring your schedule in your head as you go, don’t you? Unfortunately, that’s exactly what I do… To break free from this cycle of "writing things down just for the sake of it," I created this app. By turning your schedule into a To-Do list, just like a shopping list, you add an extra step—checking off tasks after writing them down—instead of stopping at just writing. It’s a small change, but the goal is to create a sense of accomplishment, boosting motivation for managing your schedule more effectively! How to use it? Choose the type of To-Do—habit, schedule, etc. Set a title and time quickly. Select a category to organize your tasks. As a bonus, there's also a Quick To-Do feature for tasks that don't quite need a full schedule—just like jotting down a shopping list. Download the app now and master your schedules and habits with To-Dos!
