Playbrush

Playbrush is a consumer oral-care technology brand that makes smart, gamified electric and sonic toothbrushes for children (ages 3+), pairing a Bluetooth-connected brush with a companion mobile app that turns brushing into interactive games and coaching to build good dental-hygiene habits. Founded as a UK/Austria startup and backed by Speedinvest, the Playbrush product line has since been acquired by SUNSTAR and is now sold under the GUM Playbrush brand; the former playbrush.com domain 302-redirects to a Sunstar GUM product page. Playbrush is a hardware/consumer-app company and exposes no public developer portal, API, specification, or /.well-known/ discovery surface. This profile was surfaced as a Speedinvest portfolio company and added to the API Evangelist network as a lead; enrichment confirmed there is no API surface.

Playbrush is profiled on the APIs.io network. Tagged areas include Company, Oral Care, Consumer Hardware, Smart Toothbrush, and IoT.

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/playbrush: open an issue to ask a question, or submit a pull request to add artifacts.
