## What is SpeedQX?

SpeedQX measures your internet speed with technician-grade accuracy and retro style. Run download, upload, ping, and jitter tests against Cloudflare's global edge network, M-Lab's NDT7 infrastructure, or both at once — with confidence-weighted averaging, outlier filtering, and percentile breakdowns you can trust.

DUAL-PROVIDER TESTING
Most speed test apps rely on a single server. SpeedQX tests against two independent providers — Cloudflare and M-Lab NDT7 — and merges results using methodology-appropriate weights (Cloudflare 60% for bandwidth, NDT7 60% for latency). When results diverge by more than 30%, SpeedQX flags it — which can indicate ISP throttling or network congestion.

TECHNICIAN-GRADE ACCURACY
A dedicated latency engine fires 100+ pings before your speed test even starts, with a warm-up phase discarded to eliminate DNS/TCP/TLS setup noise. Bandwidth measurements go through a three-stage accuracy pipeline: slow-start discard, IQR outlier filtering, and modified trimean computation. Jitter uses the industry-standard RFC 3550 algorithm — the same one used by Zoom, FaceTime, and VoIP systems.

ADVANCED DIAGNOSTICS
  - Bufferbloat detection grades your router A through F by measuring latency spikes under load — the #1 hidden cause of "fast but laggy" connections
  - Connection stability shows whether your speed is rock-steady or swinging wildly
  - Cloudflare AIM scores rate your connection for streaming, gaming, and real-time video call readiness
  - Latency percentiles (P50, P95, P99) show your typical ping AND your worst-case spikes
  - Tap any metric card for a plain-English explanation and color-coded quality assessment

DNS CONNECTIVITY DIAGNOSTICS
SpeedQX probes 12 major domains in parallel — Google, Cloudflare, Apple, Microsoft, Amazon, Netflix, GitHub, Wikipedia, Facebook, X, YouTube, and Reddit — with detailed per-probe DNS/TCP/TLS/TTFB timing breakdowns. Results expand automatically when your test finishes.

RETRO CASSETTE TAPE INTERFACE
A fully animated cassette tape mechanism with spinning reels that respond to your live throughput. Frosted glass controls, CRT scanline overlays, and a speaker grill pattern make every test feel like pressing play on your favorite mixtape. Set in the Guton Sans Serif typeface for a clean, geometric look.

CONFIGURABLE & TRANSPARENT
  - Choose your test provider: Cloudflare, M-Lab NDT7, or both
  - Set test duration: auto, 15s, 30s, 1min, 2min, 5min, or 10min
  - Pick your speed unit: auto-detect, Mbps, Kbps, or Gbps
  - Auto-copy formatted results to clipboard when complete
  - Read the full "How It Works" article explaining every measurement technique
  - M-Lab tests require explicit data policy consent — your privacy is respected

WHAT YOU GET
  - Download speed
  - Upload speed
  - Ping latency with P50/P95/P99 percentile breakdown
  - RFC 3550 jitter
  - Packet loss (NDT7)
  - Bufferbloat grade (A-F)
  - Connection stability rating
  - AIM quality scores (streaming, gaming, video calls)
  - DNS reachability across 12 domains with timing breakdown


## Version history (last 3 releases)

### 2.1.0 — 2026-07-07

Improved testing accuracy across providers and refined interface interactions.

### 2.0.0 — 2026-04-08

SpeedQX v2.0.0 — Technician-Grade Accuracy Overhaul

What's New:

SMARTER MEASUREMENTS
• Dedicated latency engine runs 100 pings before your speed test even starts — with percentile breakdown (P50, P95, P99) so you see your typical ping AND your worst-case spikes
• Industry-standard RFC 3550 jitter — the same algorithm used by Zoom, FaceTime, and VoIP systems
• Bandwidth accuracy pipeline eliminates TCP warm-up noise and statistical outliers for numbers that reflect what you actually experience

NEW DIAGNOSTICS
• Bufferbloat detection — grades your router A through F by measuring how much your latency spikes under load (the #1 hidden cause of "fast but laggy" connections)
• Connection stability — shows whether your speed is rock-steady or swinging wildly
• Provider divergence — when Cloudflare and NDT7 disagree, we flag it — could indicate ISP throttling
• AIM quality scores — streaming, gaming, and video call readiness ratings

BETTER RESULTS
• Tap any metric card for a plain-English explanation of what it means and how your result compares
• DNS diagnostics now test 12 major domains with detailed timing breakdown — results expand automatically when your test finishes
• Progress bars track actual data transferred, not just chunk count
• "How It Works" article explains the full methodology — tap the ? icon or the server name at the top

DESIGN
• New Guton Sans Serif typeface
• Ping and jitter now get their own full-width rows with tappable detail cards
• Accuracy metrics displayed as a card grid for easy reading on any screen size
• iPad layout optimized — UI scales to fill larger displays instead of staying phone-sized
• Refined "Test Complete" stamp with improved transparency

### 1.0 — 2026-03-18
