I'm trying to build an app that exposes a calendar for each user that stays up to date on their devices. It should work similar to Facebook's per-user read-only calendar via CalDAV.<p>Are there any paid services for this?
Just yesterday I launched the launch page for my upcoming calendar as a backend service: <a href="https://blobcal.com/" rel="nofollow">https://blobcal.com/</a> ! CalDAV support is one of the features I plan to implement if there is demand.<p>But looking at your current app website, it looks to me as if you don't necessarily require to manage your user calendars. Just getting your app information in their calendars is probably enough, whatever 3rd party provider they are using? In that case <a href="https://www.cronofy.com/" rel="nofollow">https://www.cronofy.com/</a> might be a good fit.
