Device Motion Detective vs Physics Labs
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.
Physics Labs
This app uses your device's sensors to measure various physical quantities like acceleration, magnetic fields, and sound levels. View data in coordinates or scalar magnitude, and export it to Excel for analysis. It's a digital lab for your phone.
- Measure acceleration, magnetic fields, and sound levels
- View data in X, Y, Z coordinates or scalar magnitude
- Export sensor data to Excel for analysis
- Eliminate gravity from acceleration measurements
- Measure atmospheric pressure

Physics Lab is all-in-one Sensor app which let you know physical entities around you like acceleration, magnetic fields, light intensity, sound decibel and much more... Physics Lab measures physical parameters by using your device sensors which typical device contain bunch of those sensors! Application give output in high precision with short intervals based on your sensor's capabilities. In Physics Lab, you can observe physical data in coordinates (X-axis, Y-axis, Z-axis) or in scalar magnitude. If you want, you can export sensor data into Excel by one click! Using export to excel feature you can obtain statistical information about your measurement. Physical quantities that can be measured Physics Lab: * Accelerometer: Measuring acceleration around your device. Output in m/s2 for x, y and z axes. Also, you can eliminate gravity from your measurements by one click and see real acceleration. * Magnetometer: Measuring magnetic field around your device. Output in µT for x, y and z axes. * Gyroscope: Measure angular inclination in x, y and z axes. Output in degree (°) * Luxmeter: COMING SOON * Barometer: Measure atmospheric pressure. Output in bar. * Noisemeter: Measure loudness around you. Output in dB. If you like our application, you can give us 5 stars.

Verdict
The clearest difference is review sentiment: Physics Labs at 100% against Device Motion Detective's 0%. Physics Labs also leads on update cadence (every 2 weeks vs every 13 months). Device Motion Detective's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
