Another post, another app. This one may look familiar, because (as the name suggests) its a free version of ecce's MetricClock app for iPhone. The differences are, first, iAds in the free version, and second, no ability to change settings, such as color, digital display, custom image background, etc., although you can still move the clock face around and resize it. It also does not display the percentage of your life span. So if you want to try before you buy, or you just don't care about any of that, you can now get this free app.
There are also iPad versions of both the paid and free apps, which I never noticed before, since I don't have one of those devices, yet. They appear to be the same as the iPhone versions, just reformatted.
