CmisSync vs Ride

Synchronize documents between your computer and your enterprise file server (Alfresco, SharePoint, Documentum, any CMIS-compliant server)

It is like Dropbox for Enterprise Content Management!
For file sharing/synchronization, don't get a new server or rely on the cloud: just use your existing document management server.
Free and open source.

Live Public Transport In Your Pocket

Trains, buses and everything else - Ride is a simple and practical real-time public transport app for all travelers from tourists to commuters.
Ride transforms the complicated and daunting task of navigating your way through London and distills it into really simple, easily digestible pieces. For example, you can quickly add a widget to your phone to see what buses will be arriving outside your hotel. Or you can add a widget to see if there are any delays on the train line you need to use. You can even get notified when the delays go away.
It's not just for today either, you can plan journeys and even check for planned engineering works any time from now up until 6 months in the future!
There are many other delightful experiences contained within the app, such as a live map that actually shows the trains trundling their way to their destination and an Apple Watch app that shows you at a glance how long until your last train home.
The app is currently being featured in the UK App Store (both the iOS App Store and the Apple Watch App Store).
