User reviews

Her sound

It’s not a bad story, but it would be enhanced if they had her make her familiar growling sound.

Great for Dino lovers

My son (4 years) is obsessed with dinosaurs & he loves this app.

Well done...

...nice music, but i would like to have more effects.

Left Wanting

Decent but left wanting for price - no animation, few pages, solely focused on t-rex. Son finished in like 5 min.

Too bland

My 6-y.o. son didn't ask any questions about what he saw and heard in the book - generally a sign a book was of only moderate interest. As he's currently asking 100's of questions about which critters eat what for lunch, the missing 'scary bits' are exactly the sort of thing he would have enjoyed. Pity. I would also have liked to see something at the end about fossils etc. I think the Smithsonian could have added a bit more of the science. Overall ok, but not brilliant.
