How these guides are written
They are written and edited by the team that builds Pixy. They are not written by clinicians and we do not claim medical review — where a guide makes a health claim, it is checked against published guidance from the WHO, CDC, AAP or NHS, and those pages are linked at the foot of the article so you can read the original rather than take our word for it.
Every guide opens with a direct answer, keeps typical ranges as ranges rather than targets, and says explicitly when something should go to a paediatrician instead. Where a guide discusses Pixy, the claims are limited to what can be verified against the App Store and Google Play listings — and the guides on choosing an app state where Pixy is the wrong choice, because a page that recommends itself for everything is not worth reading.
Guides are revised when the underlying guidance changes; the revision date is shown on any article that has been updated. If you find something wrong, tell us at support@pixykid.com and we will correct it.
