Starbucks
The Starbucks app is for mobile ordering, payment, and rewards. The Stars program is one of the most effective loyalty mechanics in fast food: order more, earn more, unlock tiers.
Why this score
The ordering flow is clean. The rewards program adds Stars, tier progression, bonus challenges, and exclusive offers.
Push notifications for milestones, limited-time offers, and Double Star Days create re-engagement hooks.
The breakdown
- Attention Capture3.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation5.0
Mechanics designed to bring you back — streak coercion, default push notifications, and re-engagement of dormant users.
- Social Pressure1.0
How much the experience exploits social psychology — public metrics, profile curation, and status comparison against others.
- Time Theft1.0
Mechanics that steal more time than you intended to give — no stopping cues, short units, and 'just one more' loops.
- Cognitive Erosion1.0
Mechanics that replace your independent thinking, memory, or judgment — creating dependency on the tool to function.
- Cognitive Nourishment1.0
Whether the app actively strengthens your ability to think for yourself. Shown on the label, but it does not affect the score.
