Brilliant App to increase mental calculation speed.

As far as quick nifty little apps go, this is up there, its lessons are to the point and concise. The topics covered are very useful and can be applied quickly.

I find it interesting how people complain 'you wont need to do this without a calculator anyway'. The reliance on a calculator merely makes you dependant on it, what happens when it isnt there? This app provides shortcut written and mental methods (the more practice, the more fall into the latter catagory). Extras can be purchased (for next to nothing) and what you get in the base package is good as it is.

It is very easy just to use on the bus/train during the commute and I would recommend it. Anyone taking maths or using it daily should get this app, definately worth it.

Excellent App!

Superb app, interface is simple but great, nice graphics.

There is only 20 lessons which don't take long to learn. However, I'm not sure how many maths tricks there are out there, but the practice multiple choice give it some good replay value so you'll keep coming back to keep your brain in check.

It's astonishing how quickly you pick the tricks up and how effective they are, would be nice to see some more lessons in future updates, but fantastic none the less. Wish there were more apps like this on the appstore, a definate must buy!

Great app!

The 20 lessons are great, hope there will be more available in the future. This app really helps me save time doing math questions. I'm now able to bigger math questions without using a calculator or even pen and paper.
There is still room for improvement. I think there should be a quiz option which takes random questions from each section and for every wrong answer, it should then tell you which lessons to review. I also think there should also be the option of using multiple choice or writting the answer out.
Other than that it is a great app to train ones mind!
