Must do!

I found this a little tough at first because I wasn't accustom to mental math or the methods. I spend each day doing a few quick rounds and it has helped me tremendously. I now enjoy playing with the app a lot more. I started having to use paper and pencil to work through the methods. Once I got the hang of it, I started trying it out without scratch paper. To my surprise, I like mental math. I am much quicker at knowing how to use the methods as well. Great app and a must for quick daily practice.

Concise and Effective

This app is simple in the most effective way--very easy to use and no unnecessary aspects to the app. You view and then flip the flash card. It explains how to optimally perform the math in your head, and then you select whether or not you knew the mental math steps. Highly recommend anything put out by Magoosh. Check out their website for additional stuff as well.

Amazing improvements fast!

I just started the app and I can already tell I'm getting faster at simple calculations. This app makes studying for the GRE much more manageable. If getting "number sense" is your goal, this really helps. Coming up/motivating myself to come up with my own practice problems is a challenge. This app helps with this!
