Works perfectly. Use owncloud and sync it over multiple devices.

I dumped gbmh caldav/carddav when after a phone restore, gbmh wanted to charge me again for the apps I had already paid for. They probably used a slight name change for that scam. This app works perfectly and I appreciate not having to create seperate contact/calendar accounts against the same email server.

App was easy to set up with my Fastmail calendar and contacts, and just seems to sit quietly in the background doing its thing.

I must also say Thanks for creating this app. Since I have shifted from Google Suit to Yandex, I was facing lot of challenges in managing my calendar. But with your app, you have made my life way easy and convenient again.

The app doesn't work properly, syncs only partial details. Constantly throws errors without details. Developer responsed only once with instructions that didn't work, and then went dark.
