Comments on Open Sync for Android

★★★★★ Setup with a nextcloud instance and works great

★★★★★ Good app, but when I have a new shared calendar, the app does not see the calendar, even when I refresh the open sync app, the calendar won't show up. But when I remove my account and login to my same account, the new calendar is there. So this is a feature that needs attention.

★★★★★ I used to use carddav-sync directly but, as of 2020, it's not working on my fonr anymore. My contacts remaib empty. I tried Open Sync and now I see my iCloud contacts in my phone's Contacts. I can't find anything in the settings though that will allow me to do just one-way syncing

★★★★★ Works perfectly with Baikal Server (both carddav and caldav). I just had to add two accounts because the url is different in my server for caldav and carddav. Before I used CalDav Sync and Carddav Sync which were unsupported without notice for paid users. OpenSync is a great improvement and is free of charge. I cannot understand why Google does not support dav protocols out of the box (like Apple). I think that they want to stuck people with their gmail apps and pump all the private datas.

★★★★★ As at August 2018 Open Sync works just fine with my Soho groupware server where Davdroid would not. Davdroid dev's give ZERO support, so Open Sync gets my vote!

★★☆☆☆ Installed in a Xiaomi 11T, and tried to sync with a Communigate CalDAV server. It authenticates successfully and recognizes Tasks, and Calendar. But they never appear on Google Calendar app, or Business Calendar widget.

★★☆☆☆ UNMAINTAINED AND OUTDATED RIPOFF OF DAVDROID which is now DAVx5. Hey dev, ripping off an open source project and giving it a different name does not make it a fork. COMPLETELY DISHONEST. You're even too lazy to keep your copy updated with the real app. SAD.

★★☆☆☆ Cannot sync with Nextcloud. It says that the nextcloud URL contains illegal characters when it clearly does not.

★★☆☆☆ Contacts used to work both read and write. Now contacts app only treats opensync contacts as read only. Would be nice if this app gets updated

★★☆☆☆ Opensync does not work with Synology Calendar while the very same setting works with the old and free davdroid (not davx5). Please fix the regression.
