Reviews From google play store

Excellent app, relatively simple to configure, it's stable and syncs quite quickly. It was key in moving to privately hosted services and dump Google calendar, tasks and contacts, thereby reclaiming a big chunk of privacy and control over my data. Tried other connectors, none were as simple nor stable. Also really appreciate that 'family library' is enabled, so I could purchase the licence and install on my spouse's devices too. A widget to sync an account would be a really useful!

Last updates removed the progress bar for calendar sync. Now, when it is stuck on sync, which happens often, no way to know it without going to Android Settings / Accounts and check if the sync symbol on the account is moving endlessly. That means, that the sync failed. Often, after a while, CalDav reports the sync last done ok in Android Settings / Accounts while in fact it didn't sync anything This happens since the last major update which removed the progress bar. I never have any failed sync using the Outlook CaldaSync opensource plugin on PC. Sad as it was a good app, despite sometimes failing syncs before the update. But at least, before the update, it would warn and show the progress moving bar when it did fail to sync. Issue is on 2 devices, with Android 6 and Android 9 stock Please fix

Throws sync errors with Nextcloud 15.0.7... something about missing ETags. Server side reports fatal errors of "calendar object with uid already exists in calendar collection." That said, it does seem to sync partially (calendar/tasks, but not contacts).

Does not work with daylite. Says cannot fund server.

just bought to support the fdroid version. i don't use Google play

It is easy to setup and is working with NextCloud.

Okay, I had to delete the accounts that were using DavX5 and re-create them, but now I have the right calendar names and colors. But I notice my previous review got some upvotes, suggesting I'm not the only one who noticed the behavior I described.

Helped me avoid the claws of the all-seeing-all-knowing "free cloud" and store my data on my own terms. Thank you for creating this awesome tool!

Been using this for years now with NextCloud. It's not that hard to set up, and once you have it set up, it works flawlessly without any further interaction needed.

Excellent, essential app if you want to integrate calendars, tasks and address books (contacts) with your personal cloud storage. We use it with SOGo and Nextcloud.

I am using the app for syncing my calender and contacts with my Nextcloud server. The app is worth it’s price – it does it’s job as expected for two years on my phone now.

needed a way to put my yahoo calendar on my android phone. worked great. thanks

Excellent app. works as expected without any glitches.

works flawlessly

Seems to work very well. I don't regret the money. However, there are still some issues which I don't know if they're caused by DAVx5. The main one is that postal address in contacts is not syncinc. Well, It was synced for the first time but whenever I edit it, either on the server side or on my phone, the change does not appear on the other side. Changing the address type (Home/Work) works fine but the content of the address does not. This is, however, something I probably can live with. Any help would be appreciated.

My smartphone would be useless without DAVx. I have been using it since when it was called DavDroid. Like since 4 years now. Since I do not use the calendar from Google (I'm using fruux) I needed a way to connect it to my phone. Only DAVx does the job properly. It also does integrate contacts list, and it can be configured to use the contacts' "category" field to make groups on the phone. Priceless. Bonus: you can use your ownCloud/nextCloud caldavs, even with self signed certificates.

Ich hatte nach Jahren der Nutzung jetzt ausnahmsweise mal ein Problem. Der Support hat sich aber in Rekordzeit gemeldet und es läuft wieder alles. Würde gern 6 Sterne geben. :)

If you want control of your own data, this app, and (in my case, although it's not the only option) ownCloud, are the way to go.

Went from the free version in fdroid to paid version. Keep up the good work dev.

Works perfectly with Nextcloud.
