Our science.

How Wren is grounded in research, what it measures, and what it will never claim.

What we measure, and why

[To be written] Why two answers a day, what sleep, steps and resting heart rate can and cannot tell someone, and how a record over months differs from a single day.

The research we build on

[To be written] The studies behind self-monitoring in bipolar, what they found, and where the evidence is still thin.

How we check what Wren says

[To be written] How we review the words Wren uses, what its AI is and is not allowed to do, and who reviews it.

What Wren does not claim

[To be written] Wren does not diagnose, treat or predict anything. This section will set out exactly where that line sits and why.

Publications and partners

[To be written] Anything we publish, and the clinicians and researchers we work with.
