I'm getting my CCNA(network verification) and wanted an app to practice binary. This app does this perfectly! The music during the game is just enough to focus and the game play versions of assisted/pure/insane help to memorize and build on common binary setups. It's really improved my ability to add binary faster. I recommend this for anyone wanting to practice binary or just get better at addition without using traditional methods. Thanks for making this app.

Side note- the explanations during game play are great but maybe a reference section for each category would help and a table giving the totals for the base multiplication. Also, decimal to binary/hex conversion and vice versa. But really thanks for making such an elegant app.

Great game to waste time and learn!

I have played entirely too many useless games where you chase something, destroy something or build something. I have also downloaded games to “learn”’only to be very disappointed and bored out of my mind. This game is fun and is helping me to learn. Thanks for the app!

Great for my non-math mind, and fun. Very professional look and feel to the app. Maybe y’all can teach the children programming cell phone operational systems how to create a nice look and feel instead of lollipops....?!? Maybe this app is representative of the truth that the greater intelligence and capability in humanity is not represented in the masses.
