Tacet
The brain monitor for cognitive health scores
What is Tacet?
You track your steps. Your heart rate. Your calories. But what about your brain? Tacet gives you a daily cognitive fitness score and sleep quality tracking, drawn from the rhythm of how you tap your phone. Those timing patterns carry a surprisingly accurate signal about your cognitive state. No headset, no expensive hardware, no setup. Passive tracking, built on neuroscience research from Leiden University. Traditional brain monitoring is expensive. Tacet brings it to your pocket. Start today!
From the website
Most people have no idea how their brain is performing day to day. Not because the data doesn't exist, but because nobody was reading it. Tacet captures those signals passively, in the background, and turns it into daily scores.
