http://trackchat.io/ is one I saw on hacker news today
Here are a few others.
In my humble opinion Loggr is the best out of the bunch. It has a ton of features and a really solid UI.
Each of these apps take a unique approach to the tracking problem - my goal was to make it as fast as possible, which is the most important feature to me personally. If you guys end up using any of the apps above, I'd love your feedback.
