We're addicted to Pinkberry. It makes us happy when we are feeling blue, and we totally believe the hype about the health benefits, so we consider it a guilt-free indulgence.

Now Pinkberry is feeding our habit with a new app that allows us to keep track of our loyalty points. And, oh yes. We are loyalists.

Here's how it works:

• Download the Pinkberry app.
• Register via Facebook or create an account for your Pinkcard.
• Select your favorite flavors (up to two) if you want to be notified when they're available.
• Check the box to get notified via text message for special offers.
• Choose the store closest to you.

Just for registering, you get a complimentary small fro-yo with toppings. Pinkberry also promises a free cup after your 10th purchase and celebrates your birthday in the same manner.

Thank you, Pinkberry, for making life easy. For the holidays, birthdays or any gift-giving day, you can purchase a Pinkberry eGift card, and it will be sent to your recipient via Facebook or email. If you're feeling real techy, you can "store cash" with the app, making payments and rewards easy to monitor.

Anyone who registers between now and November 21 has the opportunity to win a grand prize that includes $100 on your Pinkcard every month for a year, take-home containers every week for a year, four catered parties for up to 25 people, and $600 worth of eGifts to send. No mention of gym memberships or elastic-waist pants.

The app is pretty user-friendly — even for a not-so-technical gal like me. I love the locator tool and inbox that reminds me of my rewards, but I hate that I can only be notified about two of my favorite flavors in-store. I have more Pinkberry loves than just two.

Now I'm just waiting for the next app, which they should call Pinkberry Control. And it will be personalized: You will be satisfied with a small, Rachael.
