Automatic time tracking for your Mac

My app Timing automatically tracks time spent on your Macs. That's perfect for your purposes, as it lets your team keep track of time without having to worry about start/stop timers. Also, I'm currently working on a brand-new version, launching next month. That version has been built from the start for the needs of freelancers and small agencies, with a ton of new reporting features and optional start/stop timers if you need them. You can sign up for the beta at https://beta.timingapp.com.
