DOCSIOS

Read full description

DOCSIOS is a native companion app for DOCSight, the open-source DOCSIS network monitoring tool. It brings your cable connection metrics to iPhone, iPad, Apple Watch, widgets, and Live Activities. Get a clear overview of your connection health with signal-family cards, mini charts, range bars, recent events, collector status, speed test results, and monitoring data. DOCSIOS helps you understand downstream and upstream power, SNR/MER, modulation, OFDM/OFDMA, and uncorrectable errors without digging through raw modem data. Open focused details for channels, trends, modulation, events, speed tests, monitor targets, segment utilization, comparisons, BQM, Smokeping, snapshots, incidents, exports, and complaint workflows. The Apple Watch app and Home Screen widgets make it easy to check your connection at a glance. Local badges, notifications, and Live Activities help you keep track of relevant status changes and unacknowledged events. DOCSIOS communicates exclusively with your self-hosted DOCSight instance. No diagnostic data is collected, sold, or transmitted to third parties by DOCSIOS. DOCSIOS requires a running DOCSight backend. Full functionality requires a recent DOCSight version with current dashboard and signal-family metric support. DOCSIOS is an independent community project and is not developed or maintained by the official DOCSight team.

Volume Shader is the viral Volume Shader BM GPU test, built natively for iPhone and iPad. The Mandelbulb ray march runs in Metal on your iPhone or iPad. WHAT YOU CAN DO • Run Volume Shader BM at Simple, Standard, Advanced, or Extreme • Use Standard + 30 seconds when you want a score you can compare • Drag to rotate, pinch to zoom, and pan. Explore does not save a score. • Time CPU and memory on the same device • See GPU, memory, display, storage, and thermal state • Walk a display, touch, haptics, speaker, and battery checkup HEAT AND BATTERY This is a real GPU workload. The device can get warm and the battery will drain faster while a test is running. Extreme asks for confirmation. The app stops itself if iOS reports a critical thermal state. ADS Volume Shader is free and shows labeled native ads on Test, Device, and Checkup. Ads sit below the main content on those screens. They do not overlay the GPU test or fullscreen checkup steps. You can report an ad from the AdChoices icon on the ad. PRIVACY No account. Tests, history, and checkup marks stay on this device. Nothing is uploaded. If you tap Share, iOS’s share sheet sends only what you chose to the app you pick. Ads use the ads SDK described in the privacy policy.

Verdict

The call
