TapCounter - Cognition & Sleep

QuantActions

About this app

TapCounter enables remote collection of smartphone interaction data, cognitive tests, and questionnaires — all in one app. Directly measure smartphone interaction behavior and derive proxies for cognitive performance and sleep-related behavior. No wearables. No content capture. No participant burden.

Developed by QuantActions AG, TapCounter powers groundbreaking research linking smartphone behavior to brain function. Scientifically validated metrics have been applied in peer-reviewed studies on epilepsy, stroke, surgical recovery, cognitive aging, and neurological conditions.

What TapCounter collects:
• Cognitive Performance — action time (reaction time proxy), typing speed, behavioral age, and algorithmically derived proxies of cognitive tests from everyday smartphone use
• Sleep & Circadian — sleep onset/offset, sleep duration, circadian rhythm estimation, and sleep interruptions based on device activity patterns
• Smartphone Use — screen time, app engagement, interaction frequency, social engagement index, and patterns related to digital overuse
• Cognitive Tests — optional in-app Psychomotor Vigilance Test (PVT) for repeatable, longitudinal measurement
• Questionnaires — validated instruments including SF-36 and NASA-TLX, or deploy your own custom questionnaire

How it works:
• Runs unobtrusively in the background — passive sensing with no interaction required from participants
• Supports longitudinal studies with high participant compliance — passive design eliminates dropout
• Remote research with objective measures of smartphone activity, sleep-wake patterns, and cognitive performance
• No wearables, no content capture, no lab visits required

Designed for researchers:
TapCounter is a scientific data collection app for participants enrolled in a study managed via the taps.ai platform. The app intentionally shows minimal data to participants to prevent behavioral bias and protect study integrity. It does not provide health-related features or feedback — it is built exclusively for human subjects research.

Privacy by design:
TapCounter captures WHEN you tap — never WHAT you tap. No content, messages, images, GPS, or contacts are ever collected. Only anonymized timestamps and app labels are recorded. Data is encrypted on-device and transmitted securely to Microsoft Azure under anonymous participant codes.

For researchers:
Manage participants, monitor compliance, and download processed metrics or raw data via the taps.ai web dashboard. Metrics include cognitive performance indices, sleep and circadian measures, smartphone use patterns, and social engagement scores. As a remote patient monitoring solution, TapCounter supports longitudinal study designs with high compliance and minimal dropout.
