I can’t necessarily recommend which tool is the best for tracking your personal habits and goals, as all of them have their quirks. What I can do however (yes, it’s a bit of a cop-out) is tell you that the tool to use is whatever works best for you. I personally keep track of my daily habits and personal goals with a combo Evernote for input and then a Google spreadsheet for long-term tracking.
Second is value. Even if you went with Amazon prices instead of retail this is still a very good price for what you get. The games included this month are rated on board game geek ranging from 6.5-7.3 which is above average and way above what they could have put in the box, especially in a pop culture box. When you sign up there is a one month plan for $50 or a 6 month plan for $45 a month. If you enjoy things such as loot crate or many of the other boxes that are out there or if you like to be surprised with games every month (i know i would like games to show up every month at my house) than this is for you.
