Verify the actual transfer speeds of your connected external drives and estimate the real wattage reaching your battery. Perfect for anyone who's ever wondered "is this cable actually fast?" or "is this charger working properly?" CORE FEATURES - Data Speed Testing: Measure actual read and write speeds of external USB and Lightning drives to ensure your storage isn't bottlenecked. - Charging Speed & Voltage Fingerprinting: Calculate the actual wattage reaching your battery and use unique charging fingerprinting to estimate the specific USB-PD voltage rail (e.g., 5V, 9V, 15V) powering your device. - Charging Curve Logging: Chart your entire charging session to see how power delivery changes as the battery fills. - Device Capability Identification: See the exact maximum data speeds and charging wattage your specific iPhone or iPad model supports. - Detailed Drive Info: View connected volume names, file system formats, and total/available capacities. - Test History: Save and review past test results to compare different drives, cables, and chargers. BUILT FOR YOUR WORKFLOW - Simple, one-tap testing for both data speeds and charging rates. - Intelligent warnings to prevent testing internal storage by mistake or causing excessive drive wear. - Clear visualizations for your connection speed (e.g. USB 2.0 vs USB 3.0). EFFICIENT & PRIVATE Native SwiftUI app with minimal resource usage. Your data never leaves your device: no tracking, no telemetry, and no cloud sync. TECHNICAL NOTE Due to iOS system limitations, charging wattage is estimated by measuring battery percentage changes over time. This represents the actual power reaching the battery rather than the total charger output. For the most accurate results, run charging tests when your battery is between 20% and 50% and screen brightness is low.
