sehr gut & übersichtlich


Sehr gute & übersichtliche App, in der ich alles wichtige zum Zyklus & Co. eintragen kann! Endlich eine mit der es einfach und schnell geht, alles im Blick zu haben. Positiv auch die intuitive Bedienung.

Kleiner Alltagshelfer


Die App hat eine tolle Interface, die direkt verständlich ist. Für mich persönlich ist sie nichts, da ich meinen Zyklus nicht tracken brauche, aber für jeden der es genau planen will ist sie sicherlich hilfreich. Besonders gut finde ich die Möglichkeit einen Zyklusreport herunterzuladen, den kann man dann auch mit zum Frauenarzt nehmen.
Probiert’s einfach aus!

App ist super, Passwort-Schutz fehlt leider


Die App ist sehr übersichtlich, einfach zu bedienen und überzeugt durch ein schönes Design. Was mir zum 5. Stern jedoch fehlt, ist ein Passwortschutz. In der App werden sehr intime Daten dokumentiert und auch, wenn es nicht so häufig vorkommt, dass ein anderer als ich selbst das Handy in der Hand hat, so passiert es eben doch zumindest hin und wieder.
