App Description

If you're encountering problems please contact us: support@davx5.com or have a look at our forums: https://www.davx5.com/forums/ instead of down-voting the app so that we can provide support.

DAVx⁵ (formerly known under a different name) is the only all-in-one synchronization solution for your contacts (CardDAV), calendars (CalDAV) and your tasks (based on VTODO). The app is easy to set up and integrates perfectly with your favorite calendar/contacts app (including default apps). It can also be used seperately, if you either have CalDAV, CardDAV or only Tasks.

Compatible with almost every CalDAV/CardDAV servers and services, including Nextcloud, iCloud and Synology!

After installing, you can add a DAVx⁵ account from within the app. See https://www.davx5.com/tested-with/ for help. For more information, please see the manual: https://www.davx5.com/manual/, the FAQ: https://www.davx5.com/faq/ and our forums: https://www.davx5.com/forums/

Get the best out of this app …

⊛ … when using with your own DAV server (Radicale, DAViCal, SabreDAV, Baikal, …) and HTTPS – so you own and control all your data while having the comfort of synchronization between various devices. Or use a hosted DAV service you trust or the one of your company.
⊛ … and combine it with Evolution / Thunderbird / etc. on your computer

by Kim Perrymore,Had a calender(think is just the Samsung calender that is default) with all my data in it, downloaded another calender(simple mobile tools calender) that said to use this, to copy all data, now can't sign into your app, don't know if new calender has all data, but old calender is empty, which scares me to death if a whole years worth of data is gone, and not completely on the new calender, additionally, was sharing calendars with several others and all my data is gone from them, need help, kim

by Roy Markham,I used to be able to sync my calendar lists which are webcals on my owncloud account, now it just says no webcal app installed and then it installs icx5... which says it can't be used on an owncloud account... Update, thanks I pushed through and Didn't select authorisation and it worked. Even for OC

by Blackbeard,Wow, it actually works. I tried other free methods and they were clunky, and did not work. Bit the bullet paid for this and entered a few thing, then boom. Works flawlessly.

by Dan Vondra,Needs to be better explained, with diagrams. I was instructed by another app to install this. I can't figure out what to do with this. I really don't want to go back to Google. I just want my calendars and contacts to sync up.

by Tom Kukitz,It's the best DAV app I found. I use for my Nextcloud Calendar and Contacts and it works flawlessly! I spoke with them about 02auth and turns out I don't need it. With Nextcloud you can create passwords for specific apps. Keep up the great work! Tom
