3/5 cool idea, but way too many adds - opposite of making someone "focus" Edit 4.5/5 (after purchasing pro v) Pretty good. I wish there was a way to adjust the time goal to be something else other than 25 min. Or instead of trees being different at 60 min, 1.5 hrs. Etc. Some trees shld be diff at 40 min, 50 min etc.
