Questions

Do I have to pay to use Tomaru?

No. Learning words, FSRS spaced repetition scheduling and every public word list are free, and the core learning flow has no ads. Paid plans add pronunciation, personalisation and AI quota; they never lock the basic vocabulary features.

What is the difference between Basic, Family and PRO?

Basic is membership for one person: unlimited audio and many more AI memory tips, grammar drills and writing reviews each day. The family plan is paid by one person and makes up to six people in a party Basic members. PRO is for heavy solo use: about 2–3× the member AI limits, plus unlimited dictionary and personal articles.

Is there a free trial?

Yes. New subscribers to Basic or PRO get the first week free on monthly, quarterly and yearly plans. The family plan has no free trial.

How do I cancel?

Subscriptions are billed by the App Store or Google Play and renew automatically. Cancel anytime from your phone’s subscription settings; access continues until the end of the paid period.
