"When did I do it?"
"How much time do I have left?"
"How many times have I done it?"
Task Timer is an app that solves these questions.

For example, by registering daily routines that you tend to forget or irregularly perform, such as "drinking water", "going for a walk" or "reading a book", you can intuitively grasp the time that has passed since the last time you performed them and the time remaining until the deadline.
Not only is it a great reminder of what you need to do in the future, but it's also a great way to keep track of what you've done, such as whether you've taken your medication or not, so you don't forget.
Of course, you can also record habits you want to quit, such as being late or smoking.

Features:
One of the most unique aspects of this app is that it doesn't set a specific date and time for a deadline.
The due date is calculated starting from the last time you did it, such as 8 hours, 10 days, or a month after the last time you did it.
This allows you to visually and efficiently manage irregular tasks that are difficult to manage with calendars and reminders.

- Efficient management of irregular and hard to manage tasks.
- To keep you motivated to accomplish what you want to do.
- Visualize what you used to do casually and make it a habit.

I've tried to make it simple and straightforward without cramming it with complicated features, but with just enough features to keep it running.
I've combined reminders, counters and timers in an unprecedented way to help you be more productive with unique task management features.
