The brain monitor for cognitive health scores

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!
Hey Product Hunt! I'm Charlotte, CEO at Axite.
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.
How to use: Download the app, make an premium account trough settings and add the code FIRSTTAP for one month free!
Download the app and tell us what you think. What would you want to learn about your own brain most? We would love to hear your thoughts!
I’m curious how you’ve worked through the wellness-scoring tension on the user side.
Cognitive scores are the single most anxiety-loaded thing to quantify, because brain decline is one of people’s deepest fears. What does Tacet do for a user whose score is trending the wrong way: stay observational, suggest action, surface professional help? And from early data, does the score motivate behavior change or mostly generate anxiety without corresponding levers the user can pull? Big congrats on launching!

@ferdi_sigona Great question, and something we have gone back and forth on a lot. We know knowing your cognitive fitness can definitely be stressful for some people. However, in the same way not knowing can be stressfull for others as well. In the app we try to highlight that there methods to improve your cognitive functioning by providing science based information in articles.
We calculate a score between 0 and 100 and then display scores between certain ranges as a label for example, stable, thriving. We try to be careful with the language for downward trends so when someone's score is declining we say unstable. We chose the labels based on internal UX testing.
That being said, it is something we would love to continue receiving feedback on. Curious if you have any ideas on how to approach this?
minimalist phone: reduce your screentime
How can those behavioural patterns be spotted? I understand that activity (mainly that physical one can be tracked by external devices - rings, watches), but what if I forgot to set my smartphone to track my brain activity?
@busmark_w_nika Thank you for your question Nika! Tacet is based on peer reviewed scientific literature conducted in some of the top universities in Europe. The algorithms powering Tacet work on the concept Tappigraphy (selected articles: https://doi.org/10.1080/17489725.2022.2105410, https://doi.org/10.1038/s41746-019-0147-4) which has been used to quantify hidden human health variables such as sleep patterns, cognitive processing speeds, and human disease activities (such as in Epilepsy). Features of your taps on your smartphone, such as speed, accuracy, and time of day you tap on your phone can all be quantified to give us unique biological information about your cognitive functioning.
So, to answer your question - you do not need to turn on brain tracking on your phone, you simply have to use your phone as usual, and Tacet works away in the background to calculate your cognitive scores based on nothing but your taps!
I hope this helps you, and we are happy to see your interest in our App!
Can't wait to use the app! IOS coming soon?
@maaac Hi Mac! Thank you for your enthusiasm. We hope that the IOS release will happen in a couple of months (after summer). Ofcourse we will keep you updated on PH!

Hey Product Hunt! I'm Ruchella CTO of Axite.
🧠📱We built this app because we kept asking ourselves: why is it so hard to actually see your own brain health patterns? Tacet changes that. It passively monitors your smartphone behavior and shows you, your cognitive fitness and sleep patterns so you can make better decisions about your health.
During my PhD I worked with a group of talented scientists at Leiden University and University of Zurich who were researching how your smartphone behavior can be used to monitor your brain health. The algorithms behind this app has been published in multiple scientific publications.
Since then our team at Axite has been working hard to share the insights from these algorithms to you. We are excited to finally be able to share it today.
👩🏽💻Happy to answer any technical questions
Hey Product Hunt! I'm Dirk, Data Scientist at Axite.
What excites me most about Tacet is that it makes something real and measurable out of a signal that has always been there. Every time you tap your phone, your brain is leaving a trace. Most people have no idea. The science behind this has been quietly building for years in research labs, and now it is finally in people's hands.
As someone who works with brain data every day, I find that genuinely thrilling. Your phone already knows more about your cognitive patterns than you do. Tacet just shows you what it knows.
Can't wait to hear what you think!
Huge congrats @charlotte_franenberg 🎉 and everyone at Axite for the launch!
I really enjoyed building @Tacet . It’s been super exciting to work on something that takes everyday phone usage and turns it into meaningful insights about sleep and cognitive performance.
A lot of work went into making the experience feel simple and effortless for users, while doing some pretty complex things behind the scenes 😄
Can’t wait to see what people think and how the product evolves from here. Proud to be part of it 🙌
