5 stars: Easy to setup. Very good explanation about how it works. Let's hope results will follow and people will adhere. About the language, there is always room for complaints to people who think it should be at least in 2 languages, but indeed that would help some people to understand how to set it up.
5 stars: Being a software developer and having reviewed the public source code myself, I can definitely attest that the privacy statements are all true! This is very smart engineering work that allows anonymous matches between phones be compiled and checked, no GPS required. I'm hoping they make this mandatory for things like restaurant bookings and other close-quarters activities.
5 stars: Very smooth set-up, useful graphics in introduction, looks well designed, FAQ within the app as well. One point for improvement: select language manually, don't just use device language setting. (I prefer Dutch for Dutch apps like this one, but I'd like to avoid crappy translations of other apps by selecting English as device language.)
3 stars: feature suggestions: - notification/icon that shows when the app is running (even in the background) - show if your phone is low energy bluetooth capable (or NOT) - make it open-source ( !! ) - (willful) logging and debugging features for a level of openness and oversight that any good security software should have. keep up the good work! looks very promising [ ¡fix your outdated Playstore developer contact email! ]
