テクとく is a lifestyle app developed by SEIKO IT SOLUTION K.K. It aims to support the health and well-being of residents and employees in Tokushima Prefecture. By participating in daily walks, health check-ups, and health-related events, users can earn points that can be redeemed for special benefits.

One of the key features of テクとく is the ability to create teams. Users can form teams with friends, colleagues, or even entire companies or departments. Teams can compete against each other or work together to achieve health goals.

The app also includes a daily health management feature. Users can input their weight, blood pressure, vegetable intake, and other health-related data. This information is then graphically represented, allowing users to track their body's changes and overall well-being. It also helps users become more aware of their health and make improvements on a daily basis.

Please note that テクとく is only available for iPhone and requires access to the HealthKit app for step data. It is compatible with iPhone 5S and later models, which have built-in step sensors. However, due to limitations on data retrieval from the sensor, it is recommended to launch the app at least once every seven days. Users will also need to grant access to the Motion & Fitness activity for the app to utilize the step sensor on their iPhone.
