I reviewed 10monkeys Math World in July. You can read all about it here.
They have kindly provided me with membership codes to give to 3 lucky readers.
You can try a free demo on the website but at $5.90 a year per level or $17.90 for all four levels, it is very reasonable and comparable to a lot of the math apps available on iPad and Android tablets.
