What does your age have to do with the app? Isn't that just irrelevant information?

Give the kid a break. He's making an app, let him show it to people - antics aside.

I think it's relevant. I like browsing the Show HN section to see what kind of stuff people build, and I'm curious about the people building the stuff. I look at things differently when they are made by a high school student vs someone who has been working in the industry for a couple of years. For example, I wouldn't complain that there are lot of similar competing apps when it's clear that this is someone just trying to build their first app...

It is, but honestly most of HN is r/iamverysmart

Yes, irrelevant.

I would be careful about sharing opinions like this on HN. The Politically Correct crowd on HN will tell you to "stop being a hater"and that you need to demonstrate hopeless optimism and positivity or you can excuse yourself from all discussion.

There is no room in modern discourse for criticism - not when peoples' feelings are at stake.

This is great! Others your age smoke and use drugs... Until they realize how quickly time passes, it will be too late.

What does this mean?

From the end-users perspective, I guess they still need the app to do this, at which point you could just send two images and no one would know anyway - and it'd save you some time.

Yup, on point. This is a method of Steganography.

Very Snapchat-esque. Lots of room for improvement for UI, and social.
