Exploitive uses of the touch screen was the main focus for early iPhone applications as the touch screen was relatively new and still a novelty. This is where we saw different free iPhone applications that offered us simple pressure sensitive tools, brief slide games, and other minor amusements. Now that we have moved past the original fascination with the touch screen we have come to expect more, yet usually less has been delivered. Though many of the free iPhone applications that dominate the iTunes' App Store are in this expo display model, they try to find traditional games and functions that will take this touch screen exploitation and provide us at least a small benefit. This is the idea behind A Mood Pad – Heat Sensitive Surface.
The inventively titled A Mood Pad – Heat Sensitive Surface does little more that shows us all the wonders that the touch screen can bring us, but at the same time is a small amount of fun. A Mood Pad – Heat Surface is essentially a drawing application that reads the heat of your finger and gives a comparative amount of surface change to the approximate heat of your finger. Here you can trace whatever you like, yet it is really not detailed enough to get a real picture. Instead you just get colorful blobs that remind you of the projected background at the Electric Kool-Aid Acid Test. You rub your finger around to create the reactions, let it sit to fade away, or shake it for a quicker erase.
If you hit the awkwardly placed "i" button in the lower right hand corner you can get the options for A Mood Pad – Heat Sensitive Surface, which are actually fairly complete and involved. Here you can change color schemes completely between twelve different options, alter the sensitivity that is available, change the time it takes to fade out the marks, and even shift the size of the touch reaction that occurs. This is a stark amount of customization, but it is not going to change the experience in any fundamental way.
A Mood Pad – Heat Sensitive Surface remains a free iPhone application through a very conventional way: banner ads. These annoying branded invasions are common among free iPhone applications, especially since there is few ways for developers to release their apps as free and maintain any kind of revenue. It is not ideal, but there would be no reason to download A Mood Pad – Heat Sensitive Surface if it was not a free iPhone application.
Go ahead and get A Mood Pad – Heat Sensitive Surface, even if it does look like an application that would be used to show off the iPhone's touch screen at the Consumer Electronics Show. It is not going to give you a whole lot, but it may be the perfect thing to distract you while waiting for the bus.
Three out of five stars.
