My kids love this and fight over using it in the car. My daughter is 6 so can cope with the correct letter sounds but the option for phonic sounds would be better for my 3 year old. If you could add your own spelling lists I would pay for this app, as I could add in my daughters spellings each week!

Spell with rocket

What a great game, it's so simple and my 4 year old daughter doesn't realise she is learning. The game is unfortunately quite short so come on Little Big Thinkers more levels and more games like this please. Would definitely pay for an upgrade.

Really love the little alien building his rocket. Could you please please develop the same incentive for speech therapy. Lots of words beginning with k or s etc.
