iPad Apps My < 2 Year Old Loves: Sound Touch
by Sound Touch (go figure)
So this app is pretty straight forward and there are a lot of variations on this theme. The core function is to associate sound and images. While a lot of these apps are cartoon based, this one incorporates photography and cartoons. What makes it unique, however, is that it will display up to 4 different images/sounds for each particular object / thing. So when my son checks out a 'train' 1 of 3 will come up randomly with different sounds associated to that train, this keeps his attention level high and the boredom rate low. There are multiple categories to choose from:
Animals
Home
Environmental
Music
There are a few negatives for this app. To start there is no swipe left and right (which my son is very used to at this point), in order to switch screens you need to hit the buttons at the bottom, which he can do but it is always after an initial swipe. The second issue, which is a bit larger, is that my son tends to hit a button twice, while for most programs this is a non-issue for Sound Check it will think of the second hit to the screen as "close". So often times my son only hears about the first 5 seconds of the sound and new photograph (some are up to 30 second sound clips). I'm trying to get him to "relax" and only hit once but he doesn't seem to mind. This is why the latter issue may be neither here nor there for some, since he enjoys it just the same, and to be honest, who really wants to hear 30 seconds of an elephant. Lastly it doesn't rotate/orient with the screen because it was initially built for the iPhone, but not that this app is for iPad as well (no x2 here).
The price on this is $1.99 it's hard to complain about that but probably makes more sense to be $.99 until they enhance a bit. So while there are some wild sound boards for children out there (iSafariHD, iFarmHD) with high-flying graphics this more vanilla option with its randomness for "same objects" is what holds his attention.
