As a frequent Dunkin app user since it debuted, I can unbiasedly say this app sucks! (at least on android). It crashes all the time - especially when changing WiFi, it's unintuitive, and when there are actually promotions and offers that I would like to use, I get those push notifications through the app way too late in the day. If I received them in the morning I would be far more likely to go to Dunkin. I'm so dissatisfied that I'm brewing much more at home. Unrelated: the Dunkin perks suck!
