Google Photos
Google Photos backs up your photos and organizes them with AI. The Memories feature surfaces old photos as notifications, creating emotional re-engagement.
Why this score
Backup is pure utility. But Memories and 'On This Day' features use your sentimental attachment to bring you back and encourage browsing old photos.
Push notifications for Memories are the main engagement mechanic.
The breakdown
- Attention Capture2.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation2.0
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 Theft2.0
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 Nourishment2.0
Whether the app actively strengthens your ability to think for yourself. Shown on the label, but it does not affect the score.
Recommended usage
Turn off Memories notifications if you find yourself scrolling through old photos instead of doing what you opened your phone to do.
