Keeping Track of Time.

So you don't have to.

Chronolog aims to do only one thing, and do it well. It keeps track of what application you have open and the current title of the application. The webapp allows you to see what application you had open when and assign tags to them, to see how much time you spend on a project, Facebook, or anything else. You use it the way you want to!


Chronolog works on all of your computers and platforms. It is one of our main strengths. We'll try to make the client available for as many platforms as possible!


No manual actions required. You just install the client and everything you do is automatically registered (not quite so scary as you imagine, we'll just register what app you have running at any given time).

    When did I last work on this project?

I created Chronolog because I needed something simple that would keep track of what I was doing across my computers, which all use a different operating system. Nothing of the kind existed, and being a developer, I built it! Hopefully it'll help you too!
