Released Home Maintenance Planner App 'Mentedoki'

We have released 'Mentedoki', an app that turns your house's age and equipment into a schedule of maintenance timing and typical costs for exterior walls, water heaters, termite treatment, and more. Available on both iOS and Android.

Akatsukido Inc. is pleased to announce the release of our new mobile application 'Mentedoki', which shows owners of detached houses when their home needs maintenance and roughly what it will cost.


Cars get regular inspections; houses don't. As a result, many people only start looking for a contractor after a leak or breakdown, when there is no time to compare options and little choice but to accept the quoted price. By simply selecting the year your house was built and the equipment it has, Mentedoki lets you know what is coming next and about how much it will cost, before you are caught off guard.


Key Features:

•Automatically builds a schedule for your home from 28 maintenance cycles — just select its age, structure, and equipment
•A monthly summary plus reminders six months and one month before each item is due
•Typical cost ranges (low to high) for each job, such as exterior painting or replacing a water heater
•Record the date, cost, contractor, and photos of completed work, and the next due date is recalculated automatically
•No sign-up, no ads, and no contractor referrals — your data is stored only on your device

The core features are free. Unlimited equipment, cost ranges with a 10-year cost breakdown, and unlimited records are available with a one-time Premium purchase.


The official website (https://mentedoki.app/) also offers articles, with sources, explaining the timing and typical costs of exterior painting, water heater replacement, and termite treatment.


The app is currently available in Japanese only, on both iOS and Android. Please visit our products page for more details.
