Nice app

Ver nice app,nivce UI! The apps remind me of a hybrid of adguard/windscribe (high praise since they are the leaders in this field). Nice stats. This would go do the moon with six stars if you would allow blocklists like adguard does and allow sync across devices (I know what a nightmare that would be for mobiles) but well done, you would become leader overnight if you implemented adblocking.

Easy to use works well

Very nice app looks great wonderful value, love that it syncs across devices. Similar to AdGuard/Windscribe would love ability to add blocklists or even allow adblocking switch, and this would become a very hot service but so far good solid app
