Know & Grow
Read full descriptionHide full description
Know & Grow ist ein gemeinsames Projekt der Charité-Universitätsmedizin Berlin und der SRH University of Applied Sciences Heidelberg, Campus Berlin. Die App bietet speziell für Kinder und Jugendliche mit seltenen chronischen Stoffwechselerkrankungen entwickeltes Informations- und Aufklärungsmaterial. Seltene Stoffwechselerkrankungen sind komplex und kaum verständlich für junge Betroffene und ihre Familien. Deshalb gibt es nur wenige kindgerechte Materialien, die die Erkrankung anschaulich erklären und therapeutische Maßnahmen visuell darstellen. Know & Grow hilft betroffenen Kindern, sich entsprechend ihrem Alter und ihrer Entwicklung mit ihrer Erkrankung auseinanderzusetzen und diese besser zu verstehen. Die Blog-Inhalte umfassen spielerische Erklärungen und informatives Material für Kinder, Jugendliche und junge Erwachsene. So unterstützt die App das Selbstmanagement der Erkrankung über alle Entwicklungsstufen hinweg. Das Projekt wird aktuell als Modell in Berlin durchgeführt und profitiert Kindern, die an der Charité Berlin betreut werden. Langfristig sollen die Materialien und Inhalte deutschlandweit und international in englischer Sprache verfügbar gemacht werden. Know & Grow fördert Wissen, Selbstständigkeit und Empowerment von Kindern mit seltenen Stoffwechselerkrankungen und ihren Familien – ein wichtiger Beitrag zu mehr Lebensqualität und Sicherheit im Alltag.

Verdict
The clearest difference is in-app purchases: Know & Grow at none against DE.med's 3. Know & Grow also leads on update cadence (every 4 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
