Just some pointers
Because the nature of this app is to interact without having to share images, a lot of people with visual impairments might be drawn to it. However, I discovered that if you are interacting with someone who chooses to send you an image not only do you have 10 seconds to view the image, but you are not allowed to screenshot it. while I understand the need for this, I think it will put some of these visual impaired users at a disadvantage. As they use technology to describe photos to them, and this may make them look untrustworthy to whomever they are speaking to because they tried to take a screenshot. it is possible there may be no way around this which is okay. But it may be something to put in notice in case new users may be visually impaired. Let them know beforehand that photos will not be an option for them.
