I have downloaded several time trackers to keep track of time spent on numerous projects in small increments of time, with a lot of switching. This one beats them for its ease in switching takes. One click starts a task and clicking another task while it is counting closes the prior one and opens the new one. Some people didnt like the non-overlap, but this is key for me. Already finding that I spend more time than I thought on several projects. Well done app, thank you!
