OiTr is Japan's first service to provide sanitary napkins for free in private restrooms.
Through the app, users can receive sanitary napkins, manage and predict their menstrual cycle, and monitor their health.
==========
About receiving napkins
==========
**How to use**
1) Install the OiTr app (free).
2) Launch the app and tap the eject button on the app screen.
3) With the app screen open, bring your smartphone close to the OiTr logo (green) on the dispenser.
4) Once the communication is complete, one napkin will come out from either the left or right outlet.
5) Please use your hand to pull out the napkin that comes out of the outlet.
**Make sanitary products available to those who need them**
The service is provided by using a smartphone (app) that everyone has. This is because, in order to reach those who need sanitary products, we need to limit their use so that they are not used more than necessary.
**No user registration required for the first time! **
User registration is not required when using one napkin for the first time. All you have to do is download the app. However, if you use the second or subsequent sheets, you will need to register as a user. Please feel free to register when you have time.
**Number of sanitary napkins used**
Once you complete user registration, each person can use up to 7 tickets for free. After registration, you can use up to 7 tickets within 25 days from the first use. On the 26th day, the number of tickets will be reset and 7 tickets will be available for free again.
**Replace at least once every 2 hours**
There is a time limit on the use of sanitary napkins. After using one sheet, you can use another one 2 hours later. This 2-hour setting is because sanitary product manufacturers and obstetricians and gynecologists recommend changing your sanitary products every 2 to 3 hours.
**OiTr is very hygienic**
You can take out sanitary napkins without touching the dispenser (main body). Additionally, the dispenser has been treated with antibacterial treatment, so you can use it with confidence.
==========
New feature released!
==========
①Menstrual day prediction function
This function recognizes the day you receive a sanitary napkin as your menstrual date, and allows you to enter the start date of your period with one tap. This makes it easier for people who are using the menstrual date prediction app for the first time or who find it troublesome to enter their menstrual date.
②Schedule management function
You can see your period and ovulation dates on the calendar at a glance, making it easier to plan your schedule.
③Physical condition management function
You can record not only your weight, menstruation, and physical condition, but also your mood that day, so you can keep a detailed record of changes in your body's health status. The more information you have about menstrual dates, the better the prediction accuracy will be.
<Improvement of well-being>
We aim to create a society where all people can function more comfortably, without experiencing inconvenience or anxiety in their daily lives because of menstruation. This update is a concrete step toward better understanding women's unique health issues. Through OiTr's services, we will contribute not only to improving women's well-being, but also to changing the perception of society as a whole.
<For the future>
As OiTr further develops, we will promote a variety of initiatives that support women's health and well-being. Please feel free to send us any comments you may have regarding our services or suggestions for partnership.
“Good for you and good for society”
