IMU Research vs Sensor Data Recorder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
IMU Research
This application captures precise biomechanics data using synchronized inertial sensors. It allows for multi-limb data collection in the field, with options to log data internally or stream it to an iOS device. Exported data can be analyzed on various platforms.
- Record and time-sync up to 8 sensors
- High-frequency data capture (up to 1000Hz)
- Stream data via Bluetooth
- Export data to CSV for analysis
- Compatible with IMU BlueThunder Sensors
- Integration with Vicon Nexus

IMU Research captures inertial measurement data from IMU BlueThunder Sensors in a single application. It enables precise, multi-limb, field-based biomechanics data capture via, small, synchronized, high-frequency inertial sensors. * Record and time-sync up to 8 sensors total at 9-axis 500Hz when logged to on board memory via 2 concurrent trials * Record and time-sync up to 8 sensors total at 3-axis 1000Hz when logged to on board memory via 2 concurrent trials * Stream and time-sync up to 4 sensors to your iOS device at 9-axis 100Hz via Bluetooth * Stream and time-sync up to 4 sensors to your iOS device at 3-axis 500Hz via Bluetooth After recording, seamlessly export CSV files to any analytics platform such as Excel, MATLAB or Python for further analysis. For recordings stored on board, a desktop application is used in conjunction with IMU Research iOS. IMU BlueThunder Sensors are now fully Integrated from Vicon Nexus 2.7 as Vicon's first Integrated Inertial Measurement Unit. Vicon is an Academy Award-winning company, and the world’s largest supplier of precision motion capture and tracking systems. IMU Research is only compatible with IMeasureU’s Inertial Sensors running firmware 1.0.0 and above.
Sensor Data Recorder
This utility app records gyroscope, accelerometer, and audio data from your device. Export your recorded data as CSV or M4A files for further processing, particularly for machine learning applications. Your data remains private and is only accessible on your device.
- Record gyroscope and accelerometer data
- Record audio simultaneously
- Label recordings for ML workflow
- Adjust data capture frequency
- Download or email data
- Export as CSV and M4A

A lightweight utility in order to quickly and securely record CoreMotion gyroscope and accelerometer data together with audio data. CoreMotion data can be downloaded as a CSV (comma separated values) file and audio can be downloaded as a standard m4a file. Your data is only available on your device. Data will not be shared with others and will not be uploaded centrally. Data can then be used for further processing, mostly for machine learning (ML) / deep learning purposes. Key highlights: - Record gyroscope and accelerometer data directly from your phone's CoreMotion module - In parallel, record audio from your phone's microphone - Assign a label to each recording which can be later used in your machine learning workflow - Choose the frequency of the data to be captured per second - Download the captured data or send it via email - Further process the data within your favorite machine learning environment, e.g. using Python
