CalDAV clients connect to the caldav server to<br>synchronize, but typically cache all content.<br><br>IOS devices have CalDAV syncing built in. Android devices can add caldav<br>syncing with either a free connector or a $2.99 connector (both from the<br>google play store). OS X i believe also has CalDAV syncing built in. The<br>sunbird client (and thunderbird integration) from mozilla works great<br>for windows and linux machines. AgenDAV works as a fairly solid web client.<br><br>sabre/dav is a solid and easy to set up server (http://sabre.io/). the<br>stock installation would require a web server, php, and mysql. i've<br>written an alternate sabre/dav implementation that replaces mysql with<br>filesystem storage - you are welcome to it if you don't like running<br>databases (though it would require a bit of extra code to do handle the<br>type of authentication system you'd choose to use).<br><br>you could also just use google, as they provide caldav access to the<br>data (to which all the normal bits of caldav clients would apply -<br>they'd cache all the content and sync changes from google).<br><br>most caldav clients would save your password, so you wouldn't be<br>prompted for your password each time you started them up.<br><br>On 15-03-27 08:08 AM, Murray Strome wrote:<br>> I would like some suggestions for a calendar application that I could<br>> access from all of our computers and mobile devices, make modifications<br>> from any of them, and can be viewed and modified when there is no<br>> internet connection. <br>> We have LINUX, MS Windows, Android (tablet & phone), Mac OS (iMac and<br>> iPad mini). <br>> I think that what I want is something which would use a common file<br>> which could be in something like Dropbox so it would be available when<br>> not connected, but then automatically synchronized with all the devices<br>> whenever they were connected. <br>> I think that Dropbox is the best place to store the file (perhaps an<br>> iCal file would be a good candidate for the format), but what<br>> application could make use of it from all the devices/operating systems?<br>> Any suggestions?<br>> Thanks.<br>> Murray<br>> PS I have looked at Google Calendar and Yahoo!
