This app works perfectly for me since I want to keep track of my productivity using multiple devices. It syncs seamlessly and instantly. The interface is very pretty, and it works very reliably! Additional features that would be great: being able to “count down” instead of up on the intervals, to allow interval goals to be set in advance; better statistics (e.g., when work is getting done, what tasks work is getting done on); being able to set up a “routine” or set of tasks that can be repeated. Also a tiny thing, but ticking during the breaks is annoying for those of us who’ve conditioned ourselves to work with the ticking! This should be able to be toggled off I think. Otherwise, love it!
