If you’d like to have a globally-accessible installation of Tracks, which you could access from any computer on the internet, but you either don’t have a web server, web host, or don’t want the hassle of installing it yourself, you could try Morph eXchange. The Morph Application Platform allows you to run certain Ruby on Rails applications as services. They have some services which require a paid subscription, but their Tracks service is free to use. All you need to do is go to the homepage, signup for an account, then under subscriptions you will see Tracks listed. Click subscribe, and you can launch Tracks and enter your data.
