When you upgrade to App Premium, you'll gain access to the movement demos by celebrity athletes, be able to add macros by meal saving you time, customize your macro-counts based on your needs, and quick add macros for when you can't take a picture of the barcode.
If you choose to upgrade to a Trifecta Premium subscription your iTunes account will be charged after confirmation of purchase. The subscription options are a monthly subscription at a cost of $9.99 USD per month or a yearly subscription at a cost of $69.99 USD per year ($5.83 USD per month). Your new subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. The account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal. Your subscription price will never be increased when renewing.
Subscriptions may be managed and auto-renewal may be turned off by going to your Account Settings in the app after purchase. Once you purchase, a current billing period cannot be canceled. Any unused portion of a free trial period, if offered, will be forfeited when you purchase the Premium subscription.
