GyLog vs Battery Analyzer Pro

GyLog is a motion data logger for Gyroflow stabilization. Record gyroscope and accelerometer data from your iPhone's sensors in GCSV format — for custom post-stabilization of your own iPhone footage, or for pairing with any mirrorless or cinema camera. TWO WAYS TO USE With your iPhone — While iPhone Action Mode and LOG bring built-in stabilization, GyLog hands the control back to you. Stabilize in Gyroflow with your own smoothness, cropping, and rolling-shutter settings — beyond what automatic processing decides for you. With a mirrorless or cinema camera — Mount your iPhone on any camera with a cold shoe adapter. GyLog turns your iPhone into a dedicated Gyroflow log recorder, capturing the motion your camera can't, so you can stabilize its footage in post. KEY FEATURES • GCSV format — directly compatible with Gyroflow • Background motion logging — keeps recording even when screen is locked • Mount angle calibration — automatically detects phone orientation • Audio sync backup — optional low-bitrate audio track for drift correction • High sampling rate — up to ~100 Hz on supported devices • File management — filter, select, share, and delete recordings • AirDrop & Files app — easily export logs to your Mac for processing PRIVACY FIRST GyLog does not collect any personal data. All recordings are stored locally on your device and are never uploaded to any server. Audio sync files are stored locally and can be deleted at any time. HOW IT WORKS 1. Mount your iPhone on your camera, or hold it while shooting iPhone video 2. Tap "Calibrate Mount" to detect the phone angle 3. Press Start and begin filming 4. When done, export the GCSV file to your Mac 5. Import into Gyroflow for custom post-stabilization ABOUT GCSV FORMAT GCSV (Gyroflow CSV) is the standard format used by Gyroflow for external gyroscope data. GyLog outputs all 6 axes of motion data (3-axis gyroscope + 3-axis accelerometer) with nanosecond-precision timestamps.

Understand your device with evidence you can review. Battery Analyzer Pro combines information available through public iOS APIs, Analytics and Sysdiagnose files you choose to import, and guided checks you confirm yourself. Review key battery and device data, follow changes over time, test available hardware, and create a clear device health report—all processed on your device. KEY FEATURES Battery health and technical data Review battery health, reported and design capacity, maximum FCC, Qmax, cycle count, temperature, voltage, current, and operating-time evidence. The app clearly shows each data source and its completeness. Drain analysis and trends Compare recent Analytics records and review supporting signals such as screen activity, network use, background activity, and thermal state. When evidence is missing, the app says so instead of filling gaps with invented values. Charging speed and power reference Record charge ranges, duration, battery change, foreground coverage, and interruptions. When enough evidence is available, the app estimates net battery-side charging power. It does not claim to measure charger or wall-outlet power. Guided device checks Follow clear steps for display touch, screen uniformity, front and rear cameras, flash, microphone, speaker, receiver, haptics, Face ID or Touch ID, Wi-Fi, Bluetooth, accelerometer, gyroscope, compass, barometer, proximity sensor, and other checks available on your device. Results distinguish automatic evidence from user-confirmed observations. Device details, performance, and temperature Review model, device identifier, iOS version, system build, storage, chip, memory, display, cameras, and other identifiable components. Some component details require imported Sysdiagnose evidence. Unknown vendors remain marked as unknown instead of being guessed. Device health score Get a reference score based on available battery health, temperature, unusual drain, charging performance, guided checks, and Sysdiagnose findings. Data completeness and scoring evidence are shown alongside the result, and missing items are never treated as passed checks. Local PDF reports Create reports from currently available evidence, then preview, store, share, or delete them. Reports distinguish imported evidence, user-confirmed checks, and estimated values. Import tutorials Follow detailed steps to generate, find, share, and import Analytics and Sysdiagnose files. PRIVACY Imported files, analysis results, and reports are processed and stored locally by default and are not uploaded to a developer server. Camera, microphone, photo, or related permissions are requested only when you start a feature that needs them.
