Ask HN: Online tool for tracking time and managing solo projects

Hello Fellow HNers, I am working on multiple offices with multiple machines and need to keep track of how much time I spend on each project. I am sure there are a ton of online tools that will do such thing and I would like to know if people here have any kind of recommendation. Since, I am looking for a tool to help me better organize my work and "get things done", if people could recommend a tool that has some minimal project management and time tracking would be great. This is just for my use, there is not a real need for teams and multiple users or whatsoever. Thanks for any recommendation or comment in advance Andre
