Today's free app is My First Puzzles.
I have two opinions on this app. Firstly, look at it as just an app, it's good. It's aimed at the 2-6 crowd (although I'd almost say 2-4). The only text you'll ever see is the app name on the menu - even "Play" is simply a slowly (and lightly) flashing box with a handprint in it. You're either putting together a group of 5-6 a-piece animal puzzles or a single 5-7 piece animal puzzle. The music is simple, the play easy. Each piece drops into place on its own when you get it in the right spot, no rotating required.
Now the flip side. As a parent of a young child, this should NEVER take the place of a real, tactile puzzle. The app touts being great for small motor skill development, and I'm not sure I agree entirely. Touching and dragging a piece on the screen is one thing, holding, having to rotate and hearing the satisfying "chink" of a wood puzzle is another. And I have enough trouble letting my seven-year old play on my Kindle Fire; I'd really have to think about letting a two-year old play with an expensive device.
So as an app, it's good and is exactly what it says it is. As a "first puzzle," I'm less inclined to agree.
