In what world do these people have phones but no access to the Internet? Like why is that the first piece of information about the app? No one uses their devices like that!
I feel like I'm taking crazy pills!

No technology prevents a 3rd phone from taking a picture of the screen of a different phone.
You could try blinking different parts of the image on and off really fast.
I actually tried that for a contract project about 10 years ago. It didn't work. If you blink slower than 20 times per second it's really annoying to the user. And if you blink faster than 10 times per second it's pretty easy to take a picture with a long exposure and get the whole image. So there is no blink speed that offers even marginal protection without making the image useless.

#43They claim to protect against screenshotting- is that possible? I was under the impression that it was not something app developers were able to prevent.
I know that Signal (formerly Textsecure) won't let you take a screenshot of any text messages.
Except that it can't prevent you from taking a picture of that phone!! It's security through inconvenience!

IIRC Snapchat detects when a screenshot has been made by spotting that the touch event for a finger held down is suddenly cancelled. Maybe they're doing this, then deleting the screenshot?
Though, is it even possible to delete camera roll items for 3rd-party apps?
Edit: Ah, they just notify, not prevent, much like Snapchat:
> They cannot save it to their camera roll; and you will be notified if they ever take screenshots.
Edit 2: The old trick Snapchat used doesn't work since iOS 7. Instead, it hooks a newly-added notification that a screenshot was taken.

#45but, what happens if one of the devices are lost? how about if all the users are present via authentication and are close to each other via bluetooth or geolocation?

What's the second phone doing in that scenario?
I think the implication is that the 1st phone is the sender and the 2nd phone was the receiver, to parallel how you generally label 1st/2nd/3rd-person or -party.
But I definitely had a laugh about someone holding a crazy 5-phone contraption just to copy images.

It's explained in their FAQ: the only information they ask from you to register is your phone number.
Are there any free emails that work without requiring a cell #?
Do any free emails require a cell number? In my experience they pester you for it regularly, but continue to work fine without.

#48Are you authenticating by using the Wifi and Bluetooth addresses for input? What would stop someone from spoofing the known devices if so?
Just wondering about the setup.

The two cultures are terrible.
The cultures that try and experiment with different ideas? Rather than spending 18 months building and 'perfecting' and idea in private then releasing it to real people, doesn't it seem more efficient to Throw 10 ideas/'micro mvps' at the wall and see what sticks? Seems fairly solid to me.
Ugh. "Throw feces at the wall and see if it sticks" is the culture that gave us post-a-day blog spam instead of sporadic thoughtful writing, and github spammers pushing out whatever half-done garbage they typed in on a manic Saturday to be abandoned by Monday.
As the saying goes, "there's a reason you have two ears but only one mouth."

Or you could identify an activity or perceived problem space and spend a week or two doing real user research and be able to come up with 3 ideas that would kick the crap out of each of those 'micro mvps' because you'd be starting from real user needs. Also, if you were solving a real problem for yourself, that'd be halfway to it as well but never under-estimate the value of a little bit of user research.
