Why Port Scan Go
Professional results with zero setup.
Pay once, use forever
No subscription, no ads and no in-app purchases. One purchase unlocks every feature, permanently.
Completely private
All scanning happens on your device. No servers, no accounts, no tracking — nothing ever leaves your phone.
Professional engine
Native TCP connect scanning — the most reliable port detection on iOS, no jailbreak required.
Start in one tap
The app auto-detects your Wi-Fi subnet and pre-selects common ports, so scanning takes seconds.
Fast and full modes
Probe live hosts first for speed, or scan every target for completeness. Tune speed, timeout and concurrency.
Clear, exportable results
Live progress, per-host and per-port details with service names, and one-tap CSV export.
