A lot of interesting ideas in this product and well done on the design side. But real time messaging might not work for everyone. It's actually pretty difficult for me to focus on typing while being constantly distracted by seeing receiver typing at the same time...
Not sure I'm in the target audience to be honest... GenZ have completely different behaviour on social media and communication tools, so it might be something they'll appreciate :)
I find the concept refreshing and exciting! It seems to make messaging faster and to be a fun way of messaging. Voice messages may be more efficient in terms of information density, but not everyone always has the opportunity to record and listen to them everywhere and all the time. Too bad that the app is only available for iOS so far. I would like to see an Android app as well, so plus one for that.
