About

Zetta Link

Read full description

Zetta routes your iPhone's traffic through the proxy servers in your subscription, following the rules you set. SUBSCRIPTIONS • Paste a subscription URL and Zetta parses the server list. • Keep several subscriptions and switch between them with a tap. • Each subscription can refresh on its own schedule. ROUTING • Rule mode sends mainland China domains and IPs direct and everything else through the server. Global mode sends everything through the server. • Add your own rules: domain, domain suffix, keyword, IP range. • Type a domain to see which rule it would hit before you connect. CONNECTION • Live upload and download speed, connection time, and the last 60 seconds as a chart. • Test server latency before connecting. • A widget on the Home Screen and Lock Screen shows the connection state. • Siri and Shortcuts: "Turn on Zetta", "Zetta connect to Tokyo 01". PRIVACY • No account and no sign-up. Subscription URLs stay on your device. • Zetta has no servers of its own and sends nothing anywhere except to the servers in your subscription. Zetta needs a subscription from a proxy provider. It does not include one.
