We're so glad you'd like to share Calm. Below we have included a few tips for you as the gift giver.
While the Calm app can be downloaded for free on iOS and Android mobile devices, the gift card should be redeemed online at www.calm.com/redeem, not through the app. Gift cards do not expire and can be redeemed anytime.
Once the gift card is redeemed online, the subscription is active and the recipient can then log into Calm with the same email address they used to redeem the code and they will have access to the premium content.
You can buy a gift card here.
