Spaced Repetition, Simplified
The smartest way to remember.
A smarter, science-based way to study.
The Problem
You think you remember.
You don't.
After reading something once, your brain tricks you into feeling confident. But your actual memory is already fading — fast.
This is the illusion of learning. You feel prepared — until the exam, the interview, the moment it matters.

The Science
Why you forget — and how to stop it
Hermann Ebbinghaus discovered that memories fade in a predictable curve. Spaced repetition interrupts that curve at precisely the right moments.
Without Retentive
The Forgetting Curve
After 2 months you remember almost nothing
With Retentive
Spaced Repetition
5 quick reviews. The memory is yours to keep.
What this means for you
Without a system, you lose almost everything you study within days. That's not a personal failure — it's how the brain works.
With spaced repetition, 5 short reviews spread over a few weeks is enough to lock a memory in for months — or even years.
Each review takes just minutes. You're not re-learning — you're reinforcing what's already there. Retentive handles the timing so you don't have to think about it.
How it works — effortlessly
You don't need to study harder. You just need to review at the right time.
Drop In What You're Learning
Create a topic and add what you need to remember — like "Arrays - Two Sum" or "Japanese Verb Conjugation." Your actual notes and materials stay wherever they already are.
Hit Study
When items are due, hit Study. Open your notes, textbook, or slides and read through the flagged items. No quizzing, no pressure — just a quick read-through.
Wait for the Next Review
Retentive calculates the exact moment each memory starts to fade and schedules your next review. You never wonder what to study or when.
Retentive handles the timing.
Just open the app when it's time.
Review Again When It's Time
When the app tells you it's time, review the items again. Review an item 5 times to master it — after that, the intervals get longer and longer.
Archive, Maintain & Master
Items move through stages — from In Review to Maintenance to Mastery. Archive what you're done with and watch your mastered items grow.
Whatever you're learning, Retentive builds a system that makes you remember
Add what you need to remember. The app tells you exactly when to review.
