Where can I check when my current plan expires?

Go to “More” in the bottom menu, then “Settings” > “Subscriptions.” Here you’ll see which plan you have, its expiry date, and your purchase history.

Subscriptions must be canceled in the same place they were purchased - Google Play, App Store, or www.fitatu.com. You can cancel anytime, and no further payments will be taken. However, your plan will remain active until the end of the paid period.
