Sekai Phone Pro (for Android/iOS)


Sekaiphone is "a Realtime Speech Translation App". It supports 100 languages. Since we released the first version in 2010, it has been used by many users. We've received a lot of feedback from users. "It helped me to study foreign languages.", "We use it to talk with customers in restaurants.", "I use it to communicate with my child's homestay family." In addition, we've released "Sekaiphone Pro" which improved the translation quality. (Published on April 24, 2022)

The Pro version offers more accurate translations in certain languages by subscription. At the same time, you don't need to see any advertisements, making your use of the service even more pleasant. We provide both Android and iOS versions. You can download it free of charge.

Also, we want to contribute to the world. Therefore, we started Dream Project in December 2000.

As for Sekai Phone, we donate all profits to charitable organizations. 22 years have passed since we started this activity. I am deeply saddened by the current situation in Ukraine. As a software engineer, I wondered what I could do to help. After that, we decided to donate all the profits from Sekai Phone Pro as a part of the Dream Project.

Specifically, for the immediate period after April 1, 2022, we donate all of the profits including this product to Donation for the humanitarian crisis in Ukraine (Red Cross). I will do what I can do. If you agree with us, we would be happy to get your cooperation.
