Professional Network Testing
$4.99
Pro iPerf3 tool for iOS. Measure throughput, validate ISP/VPN changes, find bottlenecks. Shortcuts automation + x-callback-url. One purchase unlocks Mac.
Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test.
iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version.
Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks.
Key features:
- Client and server modes
- TCP/UDP tests, including bidirectional and reverse
- Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU
- Shortcuts automation + x-callback-url for power users
- Saved server profiles and favorites
- History with charts and CSV/JSON export
- Detailed metrics: throughput, latency, jitter, packet loss
Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions).
Built for network engineers, sysadmins, and power users who need accurate, repeatable results.
• Critical stability fix: eliminated rare crashes (SIGABRT) that could occur when running tests back-to-back or in rapid succession
• Resolved an edge case where concurrent test cleanup could corrupt internal state, causing the app to crash mid-session
• Fixed a rare crash on iPad when opening the Add Server screen in landscape on large-display models
• More resilient test engine — handles high-frequency test sequences without interruption
• Under-the-hood improvements for smoother and more reliable performance across all scenarios
