Good apps!

Interesting & Reader-friendly!

Really good.

Maths tricks are expertly simplified. I play on this app during those un-used and boring little moments when my computer is being slow to log on to something. There is a reward giving element for the user, which I love but would like to see that further enriched so I can incentivise myself even further.

Great app but with some possible enhancement

The app is easy to use and provides some very tricky calculations. To be honest it is quite useful because it does help me tune up my brain every day before starting my work. I'm not sure if I missed something but I was disappointed about the absence of a mixed questions mode. I think it will make the app much more interesting. The inclusion of some common formulas like those for algebra would be a great feature as well, at least to me. All in all it is worth the price and I highly recommend it to everyone who is looking for basic mathematics training package
