I guess I was anticipating this being more on the lines of BusyCal or Spanning Sync which would sync iCloud Calendar < > Google Calendar (e.g. - iCloud Work calendar syncs with Google Job calendar).

Instead, this appears to be a substitute for a cross platform calendar like Google Calendar (can be set up on Mac OS X, iOS, Android). There appears to be no way to have these entries automatically sync with existing iCloud and/or Google calendars. I assume Contacts works the same way.

I click download, but then nothing downloads and nothing can be downloaded from Fruux. Therefore the "downloaded" program has no features, is not usable and gets a bad rating.

Historically fruux was an application, we made it better and removed that requirement. These days it's just natively supported in your existing apps. See the spot on comment from Rob below.

This is *not* an app, so why is it listed on MacUpdate? You can't download and install it…

I find it really annoying that this is still on MacUpdate, even though it is completely a webapp. There is no desktop client to download, or app to install; the fruux staff who've commented on this argue that they still support their old prefpane, but there's no clear link to download it anywhere on their site. By extension, should MU list all webapps on their site?

This entry pretty much amounts to linkspam, as it misleads users into signing up for their service when they may have been expecting a desktop app-based system. Sad.

Version 1.7

I disagree.

The logical alternative would be to develop some bogus little application just for the purpose of having a presence here, and on other download sites. I applaud someone who goes the other direction: Fruux went from requiring a prefpane to requiring nothing but the free stuff you already have. Lots of other sharing-type services (often ones using readily available tech like SH, VNC, file sharing, web dav, etc etc) require you to download applications that are nothing more than switches to turn on something or run a simple terminal command.

You DO get a "desktop app-based system." You can use Contacts, Calendar, Safari, SOHO Organizer, BusyCal, or whatever else you want.

Go Fruux!


We've chosen to continue listing fruux because it was once a prefpane; the same can't be said for most web apps. I agree that it's an unusual decision on our part, but some of users find this listing valuable (including Rob_gendreau).

Dear developer: let me see if I understand this correctly. Since in the "Requirements" section of this page only PPC/Intel Macs and OSX are mentioned, are we to assume that this new Fruux scheme does not work with iOS portable devices?

We support OS X, iOS and tons of other systems. We have a list on http://fruux.com - basically every device that supports the open standards CardDAV and/or CalDAV will work fine with fruux.

It's too bad that fruux went to a web-based service and is no longer a Mac app. They were really cool.

"Note: The new fruux is based on open standards and is no longer a Mac-only application."

It appears that it's no longer an application, period, and is now only a service which works with existing applications like iCal.

I'm not sure what the MU rules are in regards to listing services which don't have companion applications for their functionality (e.g., web apps).

The legacy fruux still exists and we'll continue to run it. As for the new fruux: A companion app for the core functionality is no longer needed because we're supporting open protocols to make that happen. However there are plans to offer companion apps in the future that will help with stuff like account management and setup etc. - We'd love to hear your ideas.

What have you done to this excellent little piece of software. All this sign up at the website make fruux the default in your address book. Is this going where i think its going which is tied to you and then it becomes fully commercial. Look I know everyone has to make a living, but this isn't a piece of software anymore its a lifestyle choice.

Seems that update to Lion 10.7.2 broke fruux, unless there is again a problem with fruux servers....
