The science
Memory decays on a curve. So we review on one.
Without reinforcement, retention falls off a cliff in days. Spaced reviews flatten it, so each one buys you more time.
Without review
Retention drops below 45% in about 3 days. By week two, most of it is gone.
With RetainIQ
A 3-minute exercise lands just before you'd forget. Every success stretches the interval ~2×.
SM-2 × Ebbinghaus
Per-skill stability, ease factors and live retention scores, recalculated continuously.

How it works
Three steps. Then it runs itself.
Add your skills
Tell us what you already know (Spanish, TypeScript, music theory, finance) and when you last used it.
We track the decay
The Ebbinghaus forgetting curve, personalised per skill, calculates how fast each one is fading, in real time.
3-minute exercises
When a skill needs reinforcing, you get a targeted exercise, instant AI feedback, and a reset retention score.
Translate: “I would have gone yesterday.”
Everything you need
Most people lose skills because nothing reminds them to use them.
RetainIQ fixes that with a full toolkit built around one idea.
AI-generated exercises
Every exercise is unique and targeted to exactly what you're losing, not a generic quiz. Seven formats, instant feedback.
Scenario
A client disputes a charge after 45 days. What do you do?
Spot the error
Yo he ido al mercado ayer. What's wrong?
Live retention tracking
See each skill's retention score decay in real time, and fix it fast.
Voice practice
Talk it out. Speak your answers and hear natural voice feedback, ideal for languages.
AI coach
Ask what to review next, get explanations, or have it quiz you on a weak spot.
Friends & challenges
Share skills, climb the leaderboard and start shared challenges with friends.
Streaks, freezes & 16 badges
Build a daily habit with streaks you can protect, and earn badges for consistency, mastery and variety.
Smart reminders, everywhere

FAQ
Questions, answered
Flashcard apps help you learn new material. RetainIQ is built for skills you already have: it models how fast each one is fading, and generates fresh exercises right before you'd forget, instead of replaying a fixed deck.
