RUOK

Tell us what the problem is

We have no sales staff. We do not cold-call and we do not send direct mail. We only talk to people who get in touch with us, and we are fine if the conversation ends with “not with RUOK”.

The form asks for four things: your name, email, company and what you are dealing with. It takes about two minutes. We reply within two business days with times we could talk.

The form is in Japanese. You are welcome to write your answers in English — we read and reply in English.

If you are here about one of our apps

For questions about a certification exam prep app — a purchase, a restore, or a question in the content — use the app support page. That reaches the people who build the apps.
