The Thorlabs Powermeter App is designed to remote control the PM160 series handheld optical power meters via Bluetooth® connection. This application allows the user to read the optical power from a large needle gauge, supported by a 5 digit display with additional minimum and maximum readings. Basic settings like wavelength correction and zeroing can be performed directly from your mobile device. The app requires a Bluetooth® paired device. Supported Power Meters: - Thorlabs PM160 - Thorlabs PM160T
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 Optical Power Meter's 0%. Physics Labs also leads on update cadence (every 2 weeks vs every 12 months). Optical Power Meter'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.
