The "10th meal free" effect.
Without the punch cards
that end up in the laundry.

There's a reason coffee shops have been running loyalty stamp programs for decades. It works. Not just because people want the free coffee. It's because once someone has a progress counter running at your place, you're no longer competing on a level playing field with every other restaurant in the neighborhood on any given Tuesday night.

The psychology here is interesting. There's a concept called the "goal gradient effect" — basically, people accelerate their behavior as they get closer to a goal. Someone who knows they're on visit 4 of 5 for a free dessert will actively think about coming back sooner. They'll suggest your place when their partner asks what they feel like eating. They'll choose you over somewhere new, all else being equal.

Traditional punch cards had this effect. The problem was the friction. Cards got lost. Forgotten at home. Left in a jacket that went to the dry cleaner. And the restaurant had zero visibility into who was close to a reward or how many regulars they actually had.

Spokk moves the whole thing to a phone number. No card needed. Your customer's loyalty history is always with them, and you always know exactly where everyone stands.
