Can I use my Starbucks Mobile app to redeem a Reward?
Yes, the Starbucks Mobile app for iPhone®, Android™ and Windows works like your Starbucks Card. Just tell the barista at a participating store that you’d like to redeem your Reward and they will scan the barcode on your mobile device. You can also redeem your Reward using Mobile Order & Pay.
After you redeem, 125 Stars will be deducted from your Star balance.
