Device Motion Detective vs Sensor Data Recorder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Device Motion Detective
This utility app captures and stores detailed device motion data, including accelerometer, gyroscope, and magnetometer readings. Users can view real-time motion graphs or past records saved to the database. Data is recorded every second for up to 20 minutes per session.
- Raw accelerometer data recording
- Raw gyroscope data recording
- Raw magnetometer data recording
- Processed device-motion data
- Real-time motion graphs
- Past motion record viewing
- Data saved to database

Detect the device motion detail information and save the information into the core data system. The user could view the past motion record from the data base system. The user could view the real time device motion list or the motion graph. The app can receive four types of motion: raw accelerometer data, raw gyroscope data, raw magnetometer data, and processed device-motion data (which includes accelerometer, rotation-rate, and attitude measurements). The current version could record the device motion data for 20 minutes when tap the record button once. After 20 minutes, the user could tap the record button again. During recording, the app will insert the motion data to the database every second. Only after recording the motion data, the feature of view record motion data will display the record information. In current edition, when the device shutdown, the database information will be cleared automatically. In short, the app may be useful to some engineering users or other users who need the detail device motion data. Best wishes.
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
