★★★★ Shawn Berry 11/13/2025
Doesn't work. Won't install on my phone, tried all suggestions of restarting, clearing cache, plenty of storage available, latest android 16 update. No suggestion works. All other apps install fine.

★★★★ Thomas Markert 6/28/2024 v4.4.0.1-gplay
Switching to a new phone I was asked to pay again for the app!?! I asked the support for help but didn't get any answer to my email.
★★★★ Nigel Woolaway 6/10/2024 v4.4.0.1-gplay
I lost the original (free) version of this app (davdroid) after a reset. The free version worked fine but I cannot get this to connect with my SOGo server. Disappointing
★★★★ A Google user 4/15/2024 v4.3.15-gplay
Releases on F-Droid are lagging behind badly, forcing you to deal with update notifications on Playstore
★★★★ Tim Bateson 12/26/2023
No refunds. No exceptions! Would not work with my client, and automatic samsung sync becomes inoperable. Don't buy!
★★★★ Flakie99 7/16/2023
It did not work for me. Told me to authenticate with my email address and not user name. Did not work.
★★★★★ Ben Pearson 2/20/2026 v4.5.9-gplay
Next time you upgrade the app; don't include a nag splash that causes all syncs to fail. I need the app to keeep functioning across upgrades without my intervention.
★★★★★ Johannes Kingma 12/26/2025 v4.5.7.1-gplay
this app lacks clear user interaction. ich sehe kein sync Progress, keine Ahnung was Davx5 genau macht. Sollte ich al zwei minute auf sync klicken? werden die tasks überhaupt synchronisiert? gibt es ein Statusanzeige? Sehe ich irgendwie das DAVX5 etwas macht?
★★★★★ Tomasz Fiszer 12/2/2025 v4.5.6.1-gplay
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.
★★★★★ Martin Minter 11/27/2025
Just couldn't get it to work, so used another option.
★★★★★ Xavier Giannakopoulos 9/29/2025 v4.5.4-gplay
hello, is that it then? From perfect to impossible to repair in one sad morning? The app broke and it seems no reset proc will have it working again. Support tickets unanswered, forum discussion buried. Do I really need to look elsewhere?
★★★★★ Gunnar Guðvarðarson 8/24/2025 v4.5.3-gplay
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.
