If you've spent as much time in the App Store as we have, then you already know that there are some weird app developers out there. Aside from your standard social, news and gaming apps, there exists another group of apps -- along the outer edges of the App Store -- that is seriously bizarre. Exhibit A: "Poo Log." These apps are largely out of sight and out of mind, but some of them are actually kind of helpful.
