Amazon
Amazon's home screen surfaces personalized recommendations the moment you open it. Lightning Deals, countdown timers, and 'frequently bought together' suggestions turn a purchase into a browsing session.
Why this score
The recommendation engine is the primary engagement mechanic. Every page surfaces related products and deals.
Push notifications for deals, price drops, and delivery updates bring you back. One-click purchasing and algorithmic discovery make impulse buying frictionless.
The breakdown

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 Theft5.0
Mechanics that steal more time than you intended to give — no stopping cues, short units, and 'just one more' loops.
- Cognitive Erosion2.0
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.
