Audio Frequency Analyzer vs Docker Guard

"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone. With its simple operation, you can easily measure and evaluate your sound environment. This app measures the frequency response in 30 split band scale of 1/3 octave in real time. It can also display the FFT analysis results. It supports calibration for 1/3-octave bands. By adjusting the characteristics to match not only the built-in microphone but also your external microphone, it achieves high measurement accuracy. "Audio Frequency Analyzer" can be used for various applications, including sound room tuning, speaker settings, audio equipment testing, stage setup measurement, sound mixing environment evaluation and noise environment investigation. Features: - Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT) - FFT Analyzer (FFT) - Observation frequency range: 20 - 23000 Hz - Logarithmic amplitude display. - Touch-scroll function to adjust visible amplitude ranges. - Display the measured value of 1/3 oct bands at OCT mode. (dB@OCT) - Function to change the graph slope at FFT mode. (Slope): -3dB/oct (less than 1kHz), +3dB/oct (1kHz or higher) - Peak hold function. (Hold) - Average display function. (Avg): Time linear averaging. Fast-2.56sec, Slow-12.8 sec - Display response control. (Fast/Slow) - Reset of Measurement display position. (Scroll) - Snapshot of Measurement display. (Snap) - Calibration function in OCT mode. (Calibrate): 1/3 octave band offset and total offset setting. - Supports built-in microphone, headset microphone, and external digital audio connection. Note: The first time you access your microphone and photos after installing the app, the iOS system will ask you for permission to access them. If you have not enabled this setting, the app will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS app support page for more information about this app.

Docker Guard is the fastest way to keep an eye on your Docker hosts from your iPhone or iPad. Docker Guard is a native iPhone and iPad monitoring client for your self-hosted Docker environment. It requires the free, open-source Docker Guard Agent running on your Docker host. Connect to any server running the open-source Docker Guard Agent and get a live, industrial-style dashboard of everything that matters — CPU load, memory usage, and the state of every container, image, volume and network. When something needs a nudge, start, stop or restart containers with a single tap. LIVE DASHBOARD - Circular gauges for aggregated CPU and memory usage across all running containers - Sparkline history so you can spot trends at a glance - Engine version, architecture and host name at the top - Counts for containers, images, volumes and networks, always up to date CONTAINER CONTROL - Full container list with status, image and ports - One-tap start, stop and restart - Filter running vs. stopped - Detail view with environment and mount information IMAGES, VOLUMES, NETWORKS - Browse every image on the host with size and tags - Inspect volumes and their drivers - See each Docker network and its driver PRIVACY AND SECURITY FIRST - Your data never touches our servers. The app talks directly to your own Docker Guard Agent over HTTPS. - TLS certificates are pinned on first use (TOFU). Any change is flagged with a clear warning — you decide whether to trust the new fingerprint. - API key authentication for every request. - All credentials and certificate fingerprints live in the iOS Keychain. - Optional Face ID / Touch ID app lock keeps the app protected even if your device is unlocked. BUILT FOR iOS 26 - Native SwiftUI with the Liquid Glass look and feel - Swift 6 strict concurrency, main-actor by default - iPhone and iPad layouts, portrait and landscape - Light and dark mode - English and German SELF-HOSTED BY DESIGN The Docker Guard Agent is a small, open-source Rust service you run on your own machine as a Docker container. It mounts only the Docker socket, exposes a minimal HTTPS API, and generates its own self-signed certificate on first boot. No cloud relay, no telemetry, no third parties. Full setup instructions and the agent source are available on the Docker Guard website. Docker Guard is an independent project and is not affiliated with or endorsed by Docker Inc.
