To use the app, you must purchase a subscription for each unit, costing ¥1,500 per month. There are no free features. Obtaining each license grants you access to all features of the corresponding unit.

Each subscription allows access to only one unit. If you wish to access other units, you will need to purchase a separate subscription. There is a free trial period for the first week. After one week, you will be automatically charged ¥1,500 per month. Unless canceled, the subscription will automatically renew monthly.
