NewDays

NewDays is a cognitive health company backed by General Catalyst that delivers a clinically proven, Medicare-covered program for people living with mild cognitive impairment (MCI) or dementia. The service pairs a dedicated licensed cognitive clinician with AI-guided brain-training exercises delivered remotely from home: a free consultation, ongoing telehealth sessions, and clinician-supervised AI exercises between visits. NewDays reports that 75% of participants showed improved cognitive function on ACE-III assessments and that dementia participants delayed symptom progression by more than a year versus an untreated baseline. NewDays is a direct-to-patient telehealth offering with no public developer program, API, SDKs, or documentation surface; this profile captures the company's identity and public web properties for the API Evangelist network.

NewDays is profiled on the APIs.io network. Tagged areas include Company, Health, Cognitive Health, Dementia, and Telehealth.

NewDays’ developer surface includes signup flow, engineering blog, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/newdays: open an issue to ask a question, or submit a pull request to add artifacts.
