MyMeasureWorks
Find out what your phone can really measure
Your phone carries a dozen sensors and radios. MyMeasureWorks puts them to work as instruments in six labs: physics, radio, optics, environment, device and field. Each reading comes with the conditions it was taken under, and the app says plainly what a phone cannot measure.
For Android 10 and newer.
What is in the app
Six labs of instruments
Physics, Radio, Optics, Environment, Device and Field. A level, protractor, compass, vibration analyser, barometer-based altimeter, light meter, stopwatch, screen ruler and many more.
Readings with their conditions
Every export carries the device, sensor, rate, calibration age, reference used and method. A number without its conditions is not a measurement.
Reference, calibration, baseline
Hold a reference, calibrate against it, capture what is normal where you are, and let the app tell you whether an instrument is current.
Radio instruments
Look at GNSS satellites, Wi-Fi signal, Wi-Fi RTT ranging, the cellular network, Bluetooth Low Energy advertisements and NFC tags, using the phone's own receivers.
Optics
A flicker and PWM meter, a sky quality meter, solar siting, photogrammetry, colorimetry, a stroboscope, a mirror and a loupe, all with the phone's camera.
Honest about its limits
The catalogue says which instruments are built, which are planned and which no phone could ever be, with eleven explainers for things a phone cannot do.
Sessions and experiments
Quick measurements are recorded for 24 hours. Save one to keep it as a named session, adopt an experiment template, and export your sessions as JSON.
Fast sampling
Instruments such as the vibration analyser read the sensors at the fastest rate the phone allows.
No network permission
The app has no internet permission, no account and no telemetry: there is no network path out of it. Export is a share, on your instruction.
Questions and answers
What can the app measure?
It groups its instruments into six labs. Physics uses the accelerometer, gyroscope and magnetometer; Radio covers GNSS, Wi-Fi, cellular, Bluetooth and NFC; Optics uses the camera, torch and display; Environment uses the barometer and the light sensor; Device tests the phone itself; Field has a compass, coordinates, a stopwatch, a screen ruler and converters.
Does every instrument work on every phone?
No. An instrument needs the sensor or radio it measures with, and the app checks this without asking for any permission. The start screen shows how many of the first instruments can run on your hardware; the rest need a sensor your phone does not have.
Why does the app ask for so many permissions?
Each instrument asks only for the permission it needs, at the moment you open it, and the instruments that need none work without any. The privacy policy says which permission is used by which instrument.
Does the app send my measurements anywhere?
No. The app has no internet permission, no account and no telemetry, so there is no network path out of it. A measurement leaves the phone only when you export it and choose where to share it.
How long are my measurements kept?
Quick measurements are recorded automatically and expire after 24 hours. A measurement you save as a named session is kept until you delete it.
Does it need extra hardware?
Not for the phone's own sensors. An external tier connects hardware such as a GNSS receiver over USB, or an OBD-II adapter, and shows the instrument once the hardware is connected.
What does it cost?
Nothing. MyMeasureWorks is free. There is nothing to buy in the app, no subscription and no advertisements.
