Kids and butterflies are a winning combination. OK, it may not be the most sophisticated of apps, but it’s fine for the audience and has the added feature that the butterfly reads out the colour as the child progresses. Equally nice is the mirror effect as the pattern repeats on the other wing, after all you wouldn’t want an asymmetrical butterfly would you? Oh, you would.
For those parents out there, it’s worth a try, particularly when it’s free from here for a limited period.
