For the desktop there are time-spent trackers like RescueTime, but for the iOS phone one trick I use is to look at battery percentage spent in various apps during last 24h and 7 days. Works best if you use dedicated apps to access obvious time-wasters like instagram or facebook, but you don't get a breakdown on mobile browser(s).
