Besonders die Altersperzentilen für Körper- und Organmasse, sind eine grosse Hilfe im Alltag, z. B. beim Ultraschall. Auch der Bili-Rechner ist prima. Und all das kostenlos! Herzlichen Dank dafür! Könnte man eigentlich irgendwann zusätzlich zum BMI auch noch das - inzwischen häufiger verwendete - Längensollgewicht angezeigen? ### 5/5 — Pedz *2019-10-26* Macht einen super Eindruck. Freue mich schon, es in der Klinik einsetzen zu können. ### 5/5 — Perfect *2017-11-05, version 3.8.0* Simple and brilliant. Just what a Paediatrician needs ### 2/5 — Unable to input INCHES rather than cm? *2017-10-23* Would be more helpful if there was an option to input using inches rather than cm here in the US ### 5/5 — Im täglichen klinischen Gebrauch *2017-05-18* Danke für die nützliche App ### 5/5 — Sehr hilfreiche App *2015-01-13* Wirklich geniale App, die im klinischen Alltag Spaß macht und sehr hilfreich ist. Danke dafür! ### 5/5 — Super App für klinischen Alltag *2014-10-16* Klasse App um z.B. mal schnell Perzentilen zu überprüfen. Funktioniert super. ### 1/5 — Performance... *2014-03-27* ...auf dem iPhone 4 eine einzige Katastrophe!!!! So leider komplett nutzlos, weil in praxi nicht zu gebrauchen. Eingabe von Ziffern dauert pro Ziffer ca. 5 sec....bitte nachbessern! Danke. ### 5/5 — Perfekt! *2013-12-06* Eine super App - nicht nur für Mediziner, sondern auch für Eltern, die sich über die Größe und das Gewicht ihres Babys informieren wollen. Selbstverständlich kann die App noch viel mehr und übersteigt in ihrem Umfang die für den "Hausgebrauch" nötigen Funktionen. Ich finde es dennoch interessant zu verfolgen, ob sich das Wachstum meiner Tochter kontinuierlich im Rahmen ihrer üblichen Perzentilen entwickelt, da das Wiegen alleine ja für den Laien noch nicht so sehr viel Informationen vermittelt.
