LINE Menstrual Cycle Management and Sharing Service "Paircare" LINE Official Account Surpasses 1 Million Friends! Campaign Held to Express Gratitude

Entale Inc. (Headquarters: Minato-ku, Tokyo, Representative Director: Hinako Sakou), which operates the menstrual cycle management and sharing service "Paircare," is pleased to announce that its LINE Official Account has surpassed 1 million friends.

To express our gratitude for your continued patronage, we are launching the "What I Liked About Using Paircare" posting campaign starting today.

In this campaign, we will be accepting feedback and episodes from actual users on the theme of "What I Liked About Using Paircare" within the "Community Posts" section of the "Paircare" service.

Twenty participants will be randomly selected to receive a 500 yen Paircare original QUO card as a prize.

Background of the Campaign

In recent years, there has been growing attention on "femtech," which uses technology to solve women's health issues, and increasing interest in services that support women's health management and communication with partners.

In addition to its period prediction function, "Paircare" has aimed to create an environment where users and their partners can recognize and positively address changes in their physical condition.

We have received numerous positive comments from users such as, "I can now keep track of my period without forgetting, and my health management has improved significantly," and "My partner and I have had serious discussions about menstruation and women's diseases, and we have both learned a lot," regarding improvements in health management and communication.

As we reach the milestone of 1 million LINE friends, we planned this campaign with the desire to provide hints and a starting point for those who will use Paircare in the future, through the real experiences of our users.

In the campaign, we will be collecting user experiences on the theme of "What I Liked About Using Paircare."
