I am no 'child development' expert or trained educator so take whatever I say with a grain of salt but I think that it is a useful tool. You can gauge progress and the 'stickers' give a young child a sense of achievement. There are lots of 'games' in addition to 'real problems' and overall I think I would recommend it. Variety is important so we mix First in Math with the Singapore Math.
Basic skills like learning how to use a drawing compass, draw a straight line with a ruler (holding the ruler still is not instinctive it seems) and using a protractor really need to be done 'hands on' and this isn't possible with a computer based tool alone.
Your mileage may vary...
