What the Memory Age battery measures
Memory is not one number. Digit span, visual recall, spatial working memory, reverse span and processing speed each pull on different systems. This battery runs a short version of five free tests already on the site and combines them into one composite so you can compare days, share a result, and see which skill to train next.
The five tests
- 🔢 Number Memory — digit span. Full version: Number Memory.
- 🧩 Visual Memory — spatial recall. Full version: Visual Memory.
- 🐵 Chimp Test — spatial working memory. Full version: Chimp Test.
- 🔁 Backwards Digits — working memory. Full version: Backwards Digits.
- ⚡ Reaction Time — processing speed. Full version: Reaction Time.
How to play
- Press Start Battery and complete each mini-test in order.
- Every test ends when you miss (or hit a short cap so the battery stays under ~6 minutes).
- See your Memory Age, percentile, skill bars, strongest skill and training link.
- Share the result card, or open the full version of your weakest test to improve.
Honest limits
Memory Age is a fun, private-on-device benchmark. It is not a clinical assessment, not an IQ score, and not medical advice. Browser conditions, practice effects and fatigue all change results. If you are worried about real-world memory changes, talk to a doctor.
