MetricMe is a research tool built at the Human Computer Interaction research unit of TU Wien. It shows a week of wearable data — sleep, heart rate variability, energy expenditure, activity — and asks what you take away from it.
The tool is used for academic research only. It gives no medical advice and is not a diagnostic device.
Every version of the week view in one place. Open any of them and look through the data yourself.
Fitness trackers and smartwatches turn days of physiological measurement into a handful of numbers, rings and short written summaries. Those summaries are compact, confident, and increasingly written by software rather than by a clinician. Very little is known about what people actually conclude from them, and how much the wording and the framing of a summary changes that conclusion.
MetricMe presents the same week of data in different ways and records how participants interpret and judge it. The results feed into peer-reviewed publications on the design of personal health interfaces. No commercial party is involved, and nothing on this site is used to sell or promote a product.
You are told what is collected before anything is recorded, and you decide whether to continue. Participation is voluntary and can be stopped at any point without giving a reason.
You work through seven days of health metrics, switch individual metrics on and off, and read the summary that accompanies them.
A short questionnaire asks what you took away from the week, how much you trust it, and how you would act on it. The whole session takes about 15 to 20 minutes.
Each day is one ring. The segments are the metrics you have switched on, and the figure in the centre is a combined score for the day. The switches along the top let you add or remove metrics, and the rings redraw immediately.
Participation is anonymous. We do not ask for your name, your address or your date of birth, and we do not attempt to identify you from your answers.
Research data is stored on TU Wien infrastructure, analysed in aggregate, and may be published in anonymised form alongside a scientific article. The controller is TU Wien; the full information on the processing of personal data, the legal bases, and your rights of access, rectification, erasure, restriction, portability, withdrawal and objection is set out in the TU Wien privacy information.

MetricMe is developed and run at the research unit Human Computer Interaction (E193-05), part of the Institute of Visual Computing and Human-Centered Technology at TU Wien. The unit studies how technology is designed, adopted and experienced, drawing on informatics, psychology, sociology and design.
Questions about the study itself, about a session that went wrong, or about withdrawing your data are answered by the study team.
