I'm looking for a smart timetracker, not only to bill clients, but to efficiently scan time spent on several differents projects, with very different apps from one project to another. Someone tries Timelime, which I think it would be convenient, and which have an iOS app able to synchronise with the mac app? As there's no recent comment (nor here neither on the MacAppstore) and no possibility to try before buy, I'd like to have users feedback.
