## Review summary

Overall, users praise DAVx⁵ for reliable syncing across various CalDAV/CardDAV servers and strong, responsive support, along with good value and Google-independent operation. However, recurring concerns focus on reliability issues and inconsistent performance across devices, a lack of visible progress or status in the UI, setup/compatibility friction on some devices, and missing/awkward features like TLS client-certificate prompts and local birthday syncing. Despite these gaps, many reports remain positive when the app functions correctly.

### Pros

- Works well across multiple servers (Nextcloud, Baikal, Fastmail, etc.).
- Excellent, responsive support that resolves issues quickly (license moves, troubleshooting).
- Good value for money; affordable and time-saving compared with building a solution yourself.
- Not Google-locked; supports self-hosted and independent services, giving data independence.

### Cons

- Reliability issues and flaky behavior reported across devices and servers (crashes, failing syncs, auth problems).
- Lack of clear UI feedback and visible sync progress; users often don't know what the app is doing.
- Setup and device compatibility friction on certain devices (e.g., MIUI) and installation problems on some phones.
- Missing or awkward features such as prompts for client certificates and local birthday/calendar syncing.
