About this app

iCoi: The #1 Dating and Marriage App with Verified Doctor Registrations*
Meet doctors, graduates of top universities like the University of Tokyo, Kyoto University, Waseda University, and Keio University.
*Number of users with verified medical licenses. Based on our research as of September 2026.

【What is iCoi?】

iCoi is a dating and marriage app where users register after their educational background, qualifications, and occupation have been verified with certificates.

Developed and operated by active doctors, it has spread among doctors primarily through word-of-mouth, resulting in the industry's #1 cumulative number of registered doctors and medical students.

Since September 2026, the range of potential partners has expanded. In addition to doctors and medical students, graduates and current students of top universities such as the University of Tokyo, Kyoto University, Waseda University, and Keio University participate after verification with graduation certificates and other documents.

Recommended for those seriously looking for a marriage partner, those seeking a respectable partner, and busy working professionals who haven't had time for dating or marriage activities. 【iCoi Features】

• Verified User Background
Education, qualifications, and occupation are verified with official documents. Doctors and medical students are registered using their medical licenses and student IDs (also verified through the Ministry of Health, Labour and Welfare's qualification verification search site). Graduates and current students of eligible universities are registered using graduation certificates and degree certificates. Occupations are verified using documents such as employee IDs.

• No. 1 in Number of Doctor Members
The number of doctors and medical students with verified medical licenses is among the largest in the industry. Due to its unique network, many doctors who are only registered on iCoi are registered here.

• Emphasis on Anonymity and Security
A pre-blocking function is available targeting not only individuals but also workplaces and affiliated organizations, minimizing the risk of identity disclosure during dating and marriage-seeking activities. Since there is no need to publicly display your profile picture, you can search for a date while protecting your privacy.


【Recommended for those who:】
* Are busy doctors or graduates of top universities who haven't had time for dating or marriage hunting.
* Want to meet someone with a solid background and have a serious relationship leading to marriage.
* Are working professionals who want to find a partner more casually but safely than through a marriage agency or arranged marriage.

【Prohibited Actions】
* Posting defamatory or sexually explicit content in chats or profiles.
* Chats for the purpose of recruitment, solicitation, or sales.
* Posting personal information before matching.
If you violate these rules, your account may be frozen.

* Paid membership plans are available with automatic renewal billing every 1 month, 3 months, 6 months, and 12 months. * Payments are processed through Google Play. You can cancel automatic recurring payments at any time through the Google Play app under [Payments & subscriptions] - [Subscriptions].
