Terrible. Unspecific and poorly made.
Very disappointed. Do NOT use as an education tool. The whole thing feels hastily and carelessly constructed, and definitely not written well.
Example: 4 out of the 32 facts for crocodiles include -
''1) Crocodiles are reptiles."
''2) Their physical characteristics make them good predators."
''3) Crocodiles are fast over short distances."
''4) Crocodiles have sharp teeth.''
No kidding.
How did this make it past the Apple review team?
