How the 1-3-7 Rule Works
Three targeted reviews at the exact moments your brain is about to forget.
First Review
Within 24 hours of learning, your retention is still high. A quick review here cements the memory before decay begins.
~70% retention without reviewReinforcement
By day 3, most people have forgotten 60–80% of new info. This review fights the forgetting curve at its steepest point.
Memory curve bottoms out hereLong-term Lock-in
The final review moves knowledge into long-term memory. After this, recall becomes effortless and durable.
90%+ retention achievedSound familiar?
You study hard but forget everything before exams
Hours of effort evaporate overnight. Without spaced repetition, your brain simply doesn't prioritize the information.
Last-minute cramming that never works
Cramming creates stress, not retention. You're fighting your brain's natural forgetting curve instead of working with it.
Wasted revision sessions with no clear system
Randomly re-reading notes gives you the illusion of learning. Structured revision gives you actual recall.
What changes with 1-3-7
3× better retention
Spaced repetition is the most evidence-backed learning technique. Students using it consistently outperform peers by 200–300%.
Know exactly what to revise and when
No more guessing. The app schedules your revisions automatically — you just show up and study.
Zero exam anxiety
When you've reviewed material 3 times at optimal intervals, walking into an exam feels like reviewing familiar ground.
30 minutes a day is enough
Spaced revision is efficient. Short focused sessions beat marathon cramming every time.
Proven by science. Used by toppers.
The forgetting curve, discovered by Hermann Ebbinghaus in 1885, shows that we forget ~70% of new information within 24 hours. The solution isn't to study more — it's to review at the right moments. The 1-3-7 Rule implements this precisely.
