Comments on DAVx⁵ – CalDAV CardDAV WebDAV for Android

★★★★☆ Dimitri Bosiers · Nov 10, 2023

Works great, even has support for orbot (tor) I use it to sync mail, calendar and contacts with a privacy enhanced provider.

★★★★★ Jordan “Drak” Drakinite · Apr 8, 2025

It's been working perfectly for me without issues ever since I set it up, maybe 2 years ago or so? All I have it configured to do is sync my Nextcloud calendar and contacts. It's very much been set-and-forget.

★★★★★ Nicolas V · Dec 9, 2025

Works great for syncing my Fast mail contacts and calendars to my Android.

★★★★★ Joe Supererogatory · Feb 4, 2025

2022 comment: Works well, but please be aware that this app will NOT sync your local contacts or calendars to your CarD av or CalDav accounts. Edit: Thanks for replying! 2025 comment: Did that tool happen? It would be good to copy local contacts and calendar entries to a synced account.

★★☆☆☆ Tomasz Fiszer · Dec 2, 2025

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.

★★☆☆☆ Gunnar Guðvarðarson · Aug 24, 2025

I have wanted to use this app for _years_, but I couldn't because I didn't know it supported client certificates. I use Nextcloud and what I've always been doing when I wanted to test this app is select Nextcloud because I expected this app to prompt for a certificate when the server asked for one, but nooooo that would be user-friendly we can't have that. Please detect if you are being challenged for a client certificate in the TLS handshake and ask the user to select one.

★★☆☆☆ Ben Pearson · Feb 20, 2026

Next time you upgrade the app; don't include a nag splash that causes all syncs to fail. I need the app to keep functioning across upgrades without my intervention.
