FoxPeek is a device configuration analysis and testing utility designed for iOS users. Import a sysdiagnose or Analytics file to organize and review device information, generate clear configuration or battery analysis reports, and use Toolbox to test the display, storage, and memory of the device you are currently using. Whether you want to learn more about your device, review information about its display, battery, cameras, storage, and memory, or check its display and performance, FoxPeek turns complex diagnostic data into clear and accessible results. 1. Device Configuration Analysis Import a supported diagnostic file to view the device model, iOS version, storage capacity, memory information, storage information, and other configuration details. 2. Component Information Review key information about the display, battery, cameras, storage, memory, and other components, organized into easy-to-read categories. 3. Battery Health Analysis Import an Analytics file to review battery information such as cycle count, battery capacity, and battery health, helping you better understand the battery’s current condition. 4. Toolbox All tests and benchmarks in Toolbox are performed on the device you are currently using: - Display Test: Use different solid-color screens to help identify dead pixels, bright pixels, and display irregularities - Storage Benchmark: Measure the device’s sequential storage read and write speeds - Memory Benchmark: Measure the device’s memory read, write, and copy speeds 5. Local Reports Generate device configuration and battery analysis reports, and save them to your history for convenient viewing, comparison, and management. 6. Clear, Organized Results FoxPeek organizes complex diagnostic information into an easy-to-understand interface, reducing the time required to search through raw files. The interface is optimized for both iPhone and iPad, including landscape use. FoxPeek is useful if you want to: - Learn more about your iOS device’s configuration - Review information about the display, battery, cameras, storage, and memory - Check battery cycle count, capacity, and health - Test the display of the device you are currently using - Measure the device’s storage and memory performance - Organize device information into a clear report - Find key information in sysdiagnose or Analytics files more easily FoxPeek takes your privacy and data security seriously. Imported sysdiagnose and Analytics files, along with generated reports, are processed and stored locally on your device by default. Toolbox tests and benchmarks are also performed on the current device. Unless you choose to share content, send feedback, or use a feature that requires network access, FoxPeek does not upload the original diagnostic files or locally stored reports. Configuration analysis, device testing, and benchmark results provided by FoxPeek are for reference only. Results may vary depending on the iOS version, device model, file contents, data completeness, device temperature, and current operating conditions. FoxPeek is not an official Apple tool, and its results do not represent an official Apple diagnostic assessment.

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. A small banner sits on Test and Device. Labeled native ads sit on Test, Device, and Checkup. Ads do not overlay the GPU test or fullscreen checkup steps. You can report an ad from the AdChoices icon on the ad. After one free Test session and one free Checkup session (each about 15 minutes), the next free session waits about 30 minutes. You can wait, or watch an optional short ad to unlock unlimited Tests and Checkup for 2 hours. Declining the ad does not block the rest of the app. PRIVACY No account. History and checkup marks stay on this device. A finished GPU window can be shared as anonymous device stats (FPS, GPU, device model, screen, OS version). Turn that off in Settings. 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.
