Apps and Extensions Built by SOYOGI
Meet Soyosoyo
Completely free. No ads. Works offline. No data collected.
Every SOYOGI app is developed independently, with the help of AI. What we are aiming for is not temporary relief but a real system of care that keeps turning on its own. All of them support English, and some are available in up to 19 languages, so anyone anywhere in the world can get them for free.
We make the games and learning apps in the hope that people living in poverty, and children subjected to financial abuse, wherever they are in the world, never lose the chance to play and learn with apps that are safe and secure. The brain-training apps are for older people, to help them keep their brains healthy.
Consultations are currently offered in Japanese only. The apps themselves are fully available in English.
The web versions need no installation and open right away in the browser on an iPhone, iPad, or PC. All 37 apps also have a Google Play version (as of October 22, 2026).
Digest Video
A single digest that brings all of the apps together, made when there were 35 of them. The music is all our own as well.
