Very buggy

PureVPN has great features and it works ok on PC but this app for iOS is terrible and very buggy, not to mention very slow with a huge startup lag. It can get very frustrating to use it. My advice is look for another provider that has a stable app out on the app store.
----update----
Crashes every time when trying to connect.
