Honest comment

Great app; however, you have to purchase access to really put your mind to work. Otherwise, it is an app for a kid. Once you buy access to more advance math work out, you get to see the advantages. I like it. It does sharpen your mind to speed up your math skills that are so critical in every day life. It is also great to break the bad habit of reaching your cell phone to do simple math mind problems. You do have to put in the time to get that practice. I am a realtor and it has helped me sharpen my mind, my visualization, and this tool is turning my mind to be more active rather than passive.
