It is distributed through its own website at thymos.fit. IndieAppCircle is a peer feedback exchange, not a paid-review site: testers earn credits only for feedback the maker accepts, and nobody is paid to be positive. We record what happened here; we do not vouch for a product's business practices.

What platforms does Thymos run on?

Thymos runs on Android and Web. The maker built it for health and wellness users.

Is Thymos free?

Thymos uses a free plan with paid upgrades. Plans start at $3.99/month.

What is Thymos an alternative to?

Is Thymos still looking for testers?

Not right now. The listing is closed to new tests because the maker's credit balance no longer covers the 20-credit reward. The 3 approved reviews stay here as a record. It reopens on its own once the maker tops up — if that is you, sign in and check your dashboard.

How do testers review Thymos on IndieAppCircle?

Testers are other indie developers. They open Thymos, follow the maker's test instructions, and write up first impressions, confusing moments and bugs. The maker reads each write-up and either approves it — which pays the tester — or rejects it. Only approved feedback is counted on this page. There are no star ratings and IndieAppCircle pays nobody to review anything; it is a feedback exchange, not a review site.
