I've made a new app called Crosspass that makes end-to-end encryption for dummies. It is better than Signal et al. because it forces users to authenticate (keys) via a natural flow.
I understand why someone would use this, but having Crosspass app as closed source and not really knowing what is happening under the hood... this is not exactly my cup of tea.
Another thing, would I have to pay $1 each time I send something (after I spend my three free sends), or this is $1 paid for lifetime use?
