Anki
Anki asks you to recall information from memory before showing you the answer. That's active recall, and it's one of the most effective ways to strengthen long-term memory. Sessions have a clear end point.
Why this score
The app is built around spaced repetition, a study technique backed by decades of cognitive science research. You create your own cards and test yourself.
The daily review streak is the only engagement mechanic. It's mild compared to social media streaks because the activity itself is genuinely beneficial.
The breakdown
- Attention Capture1.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation3.0
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 Nourishment9.0
Whether the app actively strengthens your ability to think for yourself. Shown on the label, but it does not affect the score.
Recommended usage
The streak is the only engagement mechanic. Notice if it starts to feel like obligation rather than practice.
