Technology

Our mobile platform collects data from regular smartphone use - without wearables or active user entries. Data collection happens passively in the background. Our powerful AI then derives insights about the user’s brain health.

Sounds like magic?
Here is how it works.

Assessing the functioning of a brain is hard, because it is such a complex organ. Unlike other areas, such as heart diseases or diabetes, there are no simple blood tests that can give quick brain health insights. Traditionally, only laboratory-based tests and expensive brain imaging provide reliable data. QuantActions has developed a new way of deriving such insights in a user-friendly and economical way - purely from the way a user interacts with their smartphone screen (taps, swipes, etc). It turns out that this tap data contains very rich information about the brain status, for example relating to fine motor skills.
We focus only on touchscreen taps: We register when the user touches the screen to type or navigate. Important: We only collect the time of a tap, not what is typed or where the user clicks. We do not collect any content, we only look at the timing patterns: tap - no tap - tap - no tap. Sounds simple, yet from that we can derive powerful insights into the user’s brain health.
The timing data of the taps is sent to our server in regular intervals, where our powerful AI algorithms compare them to our database of clinical data and can detect patterns (“behavioral markers”). For example, the speed of tapping provides insights into the user's cognitive speed (how well the brain performs). Even very subtle changes in tapping speed over time can reveal changes in brain health (such as fatigue and risk of burnout).
Our solution does not directly observe whether the user sleeps or not. We only capture when there is a tap. But from that, we can predict the likelihood of when the user is sleeping, because sleep is driven by daily cycles of the brain, and our models are very powerful in estimating the likelihood of when a user sleeps. This has been scientifically validated in comparison with traditional sleep tracking devices, and our system performs with high accuracy. Also, we can show how tired the user is before sleeping, and how fresh after waking up. This generates a comprehensive understanding far deeper than many conventional sleep tracking tools.
Tap data contains important markers of brain activity that are relevant to neurological domains (including MS, stroke, Parkinson’s, dementia / Alzheimers) and even mental health. For example, we can detect small abnormal neural events (typically associated with seizures) in epilepsy patients. We can track markers of cognitive performance over time, which is a key ingredient in detecting age-related cognitive decline. Or we can track the brain recovery progress of patients after neuro-surgery.
Regular phone usage is sufficient to pick up the data to run our analysis. In fact, we encourage limited screen time as part of a healthy and balanced lifestyle.
Yes, there are 15+ studies ongoing or completed, and more to come. We work in a broad ecosystem of renowned scientific institutions, and our publications are featured in top-rated peer reviewed journals. See our Science section for more information.
We take privacy very seriously:
- First of all, the user is at the center: This is your phone and your data, and we want to empower you to manage your own health. Nobody else can see your health data if you don’t want to share it.
- The data is 100% anonymous: We only receive the data together with an ID. Nobody, including us, can map the ID to the user.
- For our employee health solution: The data is shared with the employer only in aggregated form (combining multiple users into a group anonymously), and only if the user actively consents.
- We only collect the timing patterns of taps and limited metadata (such as phone model type, to adjust the measurements for accuracy), no content is tracked.
- The data is encrypted and sent over a secure connection.
- We are fully compliant with European GDPR privacy regulations.
- We value transparency and publicly share our research results in the scientific community.

Our platform currently works for all versions of Android. iOS is coming soon. We also have an SDK, so our functionality can easily be integrated in third-party apps as well.
Our R&D product is already in use. For our employee health product, we are currently developing our first application. Stay tuned.
