Whatnot
Whatnot is a live shopping platform where sellers stream and auction products in real time. The live format creates urgency, FOMO, and social excitement.
Why this score
Live auctions combine time pressure, variable-reward mechanics, and social participation. Streams run for hours.
Push notifications for upcoming streams, bid alerts, and social prompts create multiple re-engagement hooks.
The breakdown
- Attention Capture7.0
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 Pressure3.0
How much the experience exploits social psychology — public metrics, profile curation, and status comparison against others.
- Time Theft7.0
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.
