Peach Bitcoin is mobile application that connects Bitcoin buyers and sellers without the need for any KYC verification or registration.
It works anywhere, anytime and you can choose many payment options including cash that you can exchange in bitcoin meetups in Europe.
Other payment methods available are Bank Transfers, Online Paymemts (Paypal, Revolut, ADVcash, Mobile Pay, Wise...), Gift Cards, and various National Options depending on your location and currency.
I think that Peach Bitcoin is currently available only in Europe, but there are plans to expand to other regions in the world.
All payment methods are available are listed on their website:

Peach Bitcoin app is available both on Android and iOS devices and only supported cryptocurrency is Bitcoin.
One issue I have is the fact that source code is private and not open source, but maybe this can change in future.
