Fitclub automatically applies the benefits like free delivery and fitcash on every meal and a variable fitcash reward for a cult/mind.fit class you attend (maximum once per day). For eat.fit, fitcash is credited only once the meal is delivered. Fitclub benefits are only applicable on orders above Rs. 99 (excluding packaging charges).
For cult/mind.fit your reward becomes available only after attendance is marked. You have to then claim your reward from the app.
