Educational toy
This app really plays like a set of old school toys. You have wheels, levers, screws, inclined planes, wedges, and pulleys — and a little playground for each one. Like real toys, there’s no real object — you just mess around with them and see what happens. There are enough fun little touches to really reward experimentation and, basically monkeying around — in a good way. My daughter found it immediately engaging — as did I.
