RTTy — Network Latency, Loss & Observability

RTTy is a native Apple-platform application for inspecting current network behavior and recent measurement history. Its engine continuously measures local network targets, renders an aggregate heatmap plus rolling-average latency in the menu bar, and opens a wide all-target detail panel and desktop dashboard.

Engineering Baseline

Platform Standards & Build Gates

Rigorous development and deployment standards applied to all software products.

Universal2 Binary Gate

Universal2 is a mandatory build gate across all East Coast Science macOS applications. Every app builds dual slices for arm64 (Apple Silicon, targeting macOS 27.0) and x86_64 (Intel, targeting macOS 26.7). The release script runs lipo -archs and fails immediately if both architectures are not present.

Developer ID Application Signing

All production binaries are signed with the company Developer ID certificate (Developer ID Application: east coast science, llc (ZU2882L4HT)), built with Apple Hardened Runtime, cryptographically timestamped, and stapled after automated Apple notarytool notarization.

Local-First & Private iCloud

Application data resides locally in the user's secure application container. Cross-device synchronization operates strictly through the user's personal, end-to-end encrypted iCloud account. No East Coast Science server retains, inspects, or has access to customer measurement or document data.

Privacy Covenant

East Coast Science applications contain zero advertising SDKs, zero user-tracking frameworks, and zero third-party telemetry. Diagnostic logging is strictly opted-in and sanitized. We do not sell or monetize personal data under any circumstances.

User Guides & Service SLAs

Guides & Reporting

Operational procedures, troubleshooting, and issue reporting standards.

Getting Started

Applications can be downloaded directly from the Apple Mac App Store or distributed as Developer ID signed disk images (.dmg). Upon first launch, macOS will verify the notarization ticket via Gatekeeper.

Reporting Defects

Please submit bug reports with complete reproduction steps to our engineering support team at [email protected]. All issues receive a written triage response within our 48-hour service level agreement.
