Make brain training honest — and measurable.
Most brain-game apps ask you to take their word that something is happening. We built CogDojo to do the opposite: show you a clear, honest read on your own training — a Brain Fitness Index, real trends, and how you compare to people your age — without overselling what any of it means.
Hi, I'm Spark.
I'm the face of CogDojo — here to cheer you through 48 games across six cognitive skills, two friendly minutes at a time.
“Brain training should be measured honestly, motivate you kindly, and never pretend to be medicine.”
That belief shapes every game we ship, every number we show, and every word we write.
Four principles we won't bend
Measurement over magic
We turn training into something you can actually see — a Brain Fitness Index, per-skill trends, and a percentile against your age group. No vague promises, just your own numbers over time.
Honesty about the science
CogDojo is built for engagement, habit, and measurement. We don't claim it cures, prevents, or treats anything, and we hedge every science claim. Trust is worth more than a bold headline.
Transparent by default
We explain exactly how the Brain Fitness Index is computed and how difficulty adapts. You should be able to judge the method for yourself, not take our word for it.
Light, kind, and motivating
Two-minute sessions, an encouraging mascot, and feedback that nudges instead of nags. Brain training should feel like a small, friendly daily win.
A phone you play on, a dashboard you think on
The games live on your phone, where quick gestures and 2–3 minute sessions belong. The web is your quiet review surface: longitudinal trends, your six-skill profile, and peer comparison by age group — room to actually study your progress.
48 games across six cognitive skills
Per-user adaptive difficulty, tuned every session
A single Brain Fitness Index that ties it all together
We measure your training. We don't make medical claims.
CogDojo is designed to keep you engaged and to track your progress over time. It is not a medical device, and we don't claim it improves real-world performance or prevents cognitive decline. When we talk about the science, we hedge — because that's the honest thing to do.
