Details

tetoru is an easy-to-use parent contact service for elementary and junior high schools.
We will support the introduction of ICT in schools by streamlining contact distribution from schools to parents and absence notifications from parents to schools.

■ What you can do with tetoru
Parents can link and contact child information by registering the contents of the registration form distributed by the school.

1. View contact delivery from school
You can receive and view the contact delivery from the school.
You can check the contact details for the entire school, grade, class, and group.

2. Send absentee notification in the app
Your child's absence notification can be completed with the app without using the phone or contact book.
You can reduce the burden of not being able to connect to the school.

3. Brother cooperation with one app
Parents who have siblings can associate their siblings with one ID.
You can save the trouble of logging in and out for each child, and complete information about your child with just one tetoru.

■ Background of the birth of tetoru
Make a new connection to your school.

I want to make school communication smoother and more connected.
Tetor was born from such an idea.
To reduce the burden on teachers and parents and to build a better relationship of trust.
By communicating with each other, we can know the present, and by communicating with each other, we will be considerate, hold hands, and discover the growth of children.
