Booster - Proxy Utility & Tool

A rule-based proxy client for iPhone and iPad. It uses the system VPN to capture traffic on the device and send it direct, through a proxy, or to a block rule — depending on your configuration. The app does not sell or host any servers; you bring your own nodes and rules.

Capture HTTP, HTTPS, and TCP traffic from apps on the device and send it to the selected proxy.
Works on Wi-Fi and cellular.
Inspect recent connections, live speed, and traffic usage.
Match rules by domain, domain suffix, domain keyword, CIDR, and GeoIP.
Test rules before you rely on them.
Import rule files from a URL or Files (including iCloud Drive).
Add nodes from subscription URLs, share links, or QR codes; refresh subscriptions on launch.
