Unfortunately, this option isn’t available at the moment.
However, you can create a new account, pay for a subscription there, and give the login details to the recipient (they can later change the password).
If you want to gift a subscription, make sure you use a different phone or log out of your own Google Play or App Store account first. Otherwise, your own subscription might be replaced.
The safest way is to log in at www.fitatu.com with the account you want to purchase for, then choose a one-time plan - this avoids linking two subscriptions to the same payment card.
