A couple of my really favorite apps that are fun, promote fine motor and visual perceptual skills are My Underwear and Sam Phibian.
My Underwear is an arcadish game with activities of catching underwear, matching colored underwear or patterns of underware to colored or patterned animals. It increases slowly in levels of difficulty to provide appropriate trials for a range of kids (and some of us adults who like…) to play. It also has a visual memory matching game and a paint your underwear activity.
Great for young children and primary school children this is a fun way to sneak in visual perceptual skill development using your mobile device. Not surprising that it rates 4-5 stars in iTunes. Costs $.99 for iPad or iPhone.
Sam Phibian is another fun app featuring a frog that eats insects. Visual tracking/scanning, attention, matching and eye hand coordination is required to make the frog eat the correct color, quantity and type of insects flying through the air.
A single tap on the insect feeds the frog. Due to the multitasking required this is best for primary school students (or adults ;o). Free; For iPad and iPod. Rated 5 stars in iTunes.
