Packet Runner brings professional-grade network diagnostics to your iPhone with iPerf3, the industry-standard network performance measurement tool.

Measure What Matters
• Throughput — Real-time upload and download speed
• TCP Latency (Ping) — Pre-test connection latency for TCP tests
• Jitter — Packet delay variation (UDP)
• Packet Loss — Connection reliability (UDP)
• Throughput Stability (Advanced) — Consistency metric from interval throughput analysis with High/Medium/Low labels

Flexible Testing
• TCP and UDP protocols
• Upload and download directions
• Configurable duration, streams, UDP bitrate, and warm-up behavior
• Test against local servers or public community servers

Community Servers
• Built-in directory of public iPerf3 servers worldwide
• Availability-aware server selection
• Automatic server health tracking based on recent test outcomes

Track Your Results
• Complete test history with filtering
• Re-test with one tap
• Result Quality scoring
• Stability labels (High/Medium/Low) for throughput consistency
• Network type capture (Wi-Fi/Cellular)

Sync and Defaults
• Test history can sync via iCloud across your Apple devices
• Default test values can sync via iCloud (server, port, protocol, mode, duration, streams, warm-up)
• Uses your Apple ID; no in-app account required

Privacy First
