    This app is doing exactly what I need it to do and without any glitches so far. CardDav sync is what I am using it for currently and have found it very reliable. Support has been excellent and fast as well for a vcard sync glitch I was having with the mail server. Highly recommended

    It does what it says and the developer was most friendly helping me to configure my yahoo account. The idea of a trial version to check if it works is great. Even if it is cheap it is always nice to be able to check if it works for me... And this was the way I discover a developer that answer questions and provide support promptly.

    the app performed a dysfunctional backup + restore, slowed down until the google play refund time passed. contact group data were not restored. would ask for refund if i could.
