VPN Application

I’m looking to develop a user interface similar to nordvpn showing the active locations using a vpn service.

I need the application to work on desktop (mac and windows) and Android and iOS. The vpn servers should come from a vpn service that lets us use their servers. I have the onboarding (login/registration already built).

Please let me know if you have any questions.Also open to different suggestions to make this happen as quick as possible.
