If you've been watching the fourth season of Silicon Valley, which aired its season finale this past weekend, you're likely familiar with the Not Hotdog app. It initially started as a failed object recognition app, but mutated into a real-world app for iOS, along with promotional material for the HBO show. 

Now, an Android version of the app has landed on the Google Play Store, allowing users to take part in the absurdity too. 

While the app is indeed a ludicrous sounding concept, the technology behind is quite sound for the most part, with it capable of discerning the difference between objects that are hotdogs, and those that are not. 

It has also led to quite a few funny uses of the app, with the best we've seen yet being @david_kha, who placed ketchup on a number of objects to try and fool the Not Hotdog app.
