Have been using a version of this app for years. Has everything I need — way to track time, allows me to group activities into larger categories, see some basic analytics, and now includes a Pomodoro timer. (I also recently got an Apple Watch and it’s also been very convenient to start/stop activities without picking up my phone!) Whenever I’ve reported issues, the developer is very responsive, which I really appreciate.Very occasionally, I check what other productivity tools have popped up. They’re always expensive and bogged down with useless features, usually at the expense of the core features. Some have a more polished interface, but this has everything I need and it does it well.
