US only, welcome to the "global system of interconnected computer networks". Hope Richard's P2P-internet will work better :)

Yup sorry about that, the app is available only in the US (& Canada) due to some legal restrictions we couldn't avoid. FWIW I also worked about on Richard's New Internet concept for this season so I definitely hear ya ;)

Don't apologize here. Apologize on the product page for this and all other similar things you do in the future to reduce amount of surprise for customers (and as a result also enmity created towards you).

It was written in Objective C?

It's actually written in React Native with a fair bit of C++ (TensorFlow), and some Objective-C++ to glue the two. One cool thing we added on top of React Native was a hack to let us inject new versions of our deep learning model on the fly without going through an App Store review. If you thought injecting JavaScript to change the behavior of your app was cool, you need to try injecting neural nets, it's quite a fee…

I really have no idea what any of that means, no Android then?

Ha didn't expect this to end up here. If anyone is interested, I'm working on a blogpost explaining how we built the app in detail… It uses embedded TensorFlow on device (better availability, better speed, better privacy, $0 cost), with a custom neural net inspired by last month's MobileNets paper, built & trained with Keras. It was loads of fun to build :)

Does it detect penises? I don't want to try it myself.

Only American ones it seems

Is that a joke, or does circumcision or its absence actually have an effect on the classifier? Or do you refer to some other characteristic? Offhand I can't really think of a more marked difference between American and non-American penises than the relatively high US circumcision rate, but I'm not so much a subject matter expert as just an interested amateur, and perhaps I overlook something here.

(If anything, I'd expect the classifier to more reliably call "not hot dog" on a penis that's circumcised, since hot dogs rarely are.)

AWESOME! Can you please elaborate a bit more on the model architecture and what you tried with respect to transfer learning? Did you use an imagenet architecture e.g. VGG and retrain from scratch or a custom architecture? Did you try chop off the last 1/2/3 layers of a prerrained mode and fine-tune? Bonus points: 1. How much better were your results trained from scratch vs fine-tuned? 2. How long did it take to train…

Hey so I actually tried Vgg, Inception and SqueezeNet, out of the box, chopped and trained from scratch (SqueezeNet only for the latter due to resource constraints). We ended up with a custom architecture trained from scratch due to runtime constraints more so than accuracy reasons (the inference runs on phones, so we have to be efficient with CPU + memory), but that model also ended up being the most accurate model…

As someone currently writing an app which uses a retrained Inception model, I watched the show pointing and laughing (and then crying) at the same issues and frustrations. The accuracy of the show and especially this episode has been just brilliant.

Thanks for sharing all the tech details too, it's been great to read. I'm even more amazed to see it as a real app, that I didn't expect!

Will it be released world wide

I second this, world wide release would be nice. It's a shame how many "locale neutral" apps end up walled in on the US app store.

Is there any specific reason why this happens, just seems to me like you get worse reach and no benefits? Especially for a marketing stunt like this.

And the World's Most Entitled comment award goes to...

The authors of this app don't owe you anything and are entitled to sell it in whatever countries they so choose. Additionally, the app doesn't even get listed in countries it's not available in. The only reason you and other non-US users (such as myself) are able to see it is because the OP posted a link to the US version of the app store on a forum where the vast majority of visitors are US-based. Get off your high horse.

Great work, man.

The effort you put into the show is much appreciated.
