Erster Eindruck --> PERFEKT Nachdem seit dem Update der Gmail App am 13.11.25 die EAS Schnittstelle nicht mehr ordentlich synchronisiert, sind Kontakte, Kalendereinträge usw von unserem Tobit-/Davidserver nicht mehr da. Nach rund 10 Jahren Nutzung ist das sehr ärgerlich. Auf das neue Update von Gmail gewartet - das kam gestern - leider keine Änderung. Heute morgen nach Dauerärger habe ich nun Eure App installiert! Ich bin sehr zufrieden!!

Very flaky and unstable, doesn't work with radicale very well. I would refund if I could, as it continuously spams me with auth issues, yet when I go to the app and sync manually, it all works fine. I can't really trust it does its job correctly. Waste of money and time.

Funktioniert perfekt und ist intuitiv zu bedienen. Ich nutze die App in Kombination mit einem Baikal-Server auf dem NAS. Für Aufgaben und Notizen ist auf den Androiden JTX im Einsatz.

Der Support durch das Team ist erstklassig. Kompetent, freundlich und schnell. Nach nur einem Tag waren aufgetretene Synch-Fehler behoben. Danke dafür.
