With easy-to-use design and a vast range of editing features, it is a must-have app for anyone who takes photos & videos. By conneting the APP to a ZHIYUN professional stabilizer, it helps you create film-grade footage that is once only possible with a crew.

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.
