I know the answer to this question, but I don’t feel like picking apart each one of them. My favorite is Time Doctor because it offers so many customization options and it syncs with my Google calendar and Outlook contacts. The other day, I accidentally deleted a meeting that was scheduled for 10:00 AM – which would have been an hour after we were supposed to start working on a case — and the app let me know about it right away! It also has alerts for unread emails as well as missed calls from clients or family members. If you want your time tracking info automatically uploaded into Box (I use Dropbox), then all you need to do is start using the free version of the app first. Then upgrade when you’re ready for all those bells and whistles!
