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!
We are so proud of this launch and genuinely excited to share Tacet with you. Perfect for anyone who has always wanted a deeper look into their brain activity, without the price tag or the clinic visit!🧠
It turns out the way you tap your phone tells you something about your brain. Not what you type, not which apps you open, but the timing between your taps. That rhythm shifts when you are cognitively sharp, when you are fatigued, when your sleep has been poor. It is a signal that has always been there. We just built the software to read it. Brain monitoring has always been locked away in expensive hardware and clinical settings. Tacet changes that. It runs quietly in the background, no difficult setup and no expensive headset, and turns that tap signal into something you can actually use.
Here is what you get: 📱 A cognitive fitness score that shows how sharp your brain is performing, whenever you like 💤 Sleep quality tracking based on your behavioural patterns 📈 Longitudinal trends so you can see how your brain changes over days and weeks ☕ A log to add context like stress, caffeine, or a bad night, so your data actually means something.
📏 The perfect tool to measure whether a lifestyle change is having a real effect on your brain's performance
One thing worth knowing: the scores get more accurate after about two weeks of use. The algorithm needs time to learn your personal baseline. So download it today, let it run, and see your cognitive scores appear over time. That is when things start to get really interesting!
We are building towards a full remote brain monitoring platform, but we wanted to get something real into people's hands now. A first glimpse into your own brain, accessible to anyone with an Android smartphone (we are still working on the IOS release!!)
🎉 Product Hunt exclusive: we are offering a special discount during the first week of launch: A one month free trial! Grab it while it lasts.

Who hunted Tacet?
Tacet was hunted by Charlotte. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
