イツダッケ：最後にやった日を記録、次いつやるかを教えてくれる

"When was the last time I did this?"

Itsudakke is a simple app for managing regularly performed tasks by recording the date they were last completed.

While we often remember daily tasks, we surprisingly forget about chores, maintenance, and replacements of everyday items that only happen every few weeks or months.

It allows you to record and manage "occasional tasks" such as washing bedding and sheets, changing toothbrush and razor blades, cleaning air conditioner filters, changing water filter cartridges, changing car oil, checking disaster preparedness supplies, getting a haircut, changing fish tank water, and backing up your PC.

While typical to-do apps and checklists focus on managing "what to do next," Itsudakke specializes in recording "the last time you did it."

By setting an interval (number of days) for each task, they are displayed in order of their due date, making it easy to see "what needs to be done now." It provides simple task management without the confusion of wondering what to do next.

Recording is just one tap after opening the app.

Because you can record things as soon as you remember, you can easily continue managing habits and keeping track of regular maintenance.

【Recommended for people who:】

・Tend to forget when they last washed their bedding or sheets

・Want to manage when to replace toothbrushes, razor blades, etc.

・Don't want to forget household chores or equipment maintenance

・Want to record regular inspections of cars, bicycles, disaster prevention supplies, etc.

・Are looking for a simple to-do/task management/habit management app

・Want to quickly check what needs to be done from a home screen widget

Itsudakke prioritizes "ease of use" over multi-functionality.

There are no unnecessary features.

Record the last time you did something, and check what you need to do next. That's all.

This app is designed to eliminate the question, "When did I last do that?"
