About this app

This app uses internal smartphone sensors to collect, display, record, and export .csv data files. See www.vieyrasoftware.net to (1) read about case usage in research and development, and (2) get lesson plans for educators of science, technology, engineering, and mathematics (STEM) fields, including physics. Sensor availability, precision, and accuracy are dependent upon smartphone hardware.

Sensors, generators, and data analysis tools include the following:

KINEMATICS
G-Force Meter - ratio of Fn/Fg (x, y, z and/or total)
Linear Accelerometer – acceleration (x, y, and/or z)
Gyroscope - radial velocity (x, y, and/or z)
Inclinometer - azimuth, roll, pitch
Protractor - angle from vertical or horizontal

ACOUSTICS
Sound Meter - sound intensity
Tone Detector - frequency and musical tone
Tone Generator – sound frequency producer
Oscilloscope - wave shape and relative amplitude
Spectrum Analyzer - graphical FFT
Spectrogram - waterfall FFT

LIGHT
Light Meter - light intensity
Color Detector - detects HEX colors within a small rectangle area on the screen via the camera.
Color Generator – R/G/B/Y/C/M, white, and custom color screen
Proximeter - periodic motion and timer (timer and pendulum modes)
Stroboscope (beta) - camera flash
Wi-Fi - Wi-Fi signal strength

MAGNETISM
Compass - magnetic field direction and bubble level
Magnetometer - magnetic field intensity (x, y, z and/or total)
Magna-AR - augmented reality visualization of magnetic field vectors

OTHER
Barometer - atmospheric pressure
Ruler - distance between two points
GPS - latitude, longitude, altitude, speed, direction, number of satellites
System Temperature - battery temperature

COMBINATION
Multi Record - choose one or more of the above sensors to collect data at the same time.
Dual Sensor - display data from two sensors on a graph in real time.
Roller Coaster - G-Force Meter, Linear Accelerometer, Gyroscope, and Barometer

PLOTTING
Manual Data Plot - enter data manually to generate a graph.

GAME
Play - challenges

FEATURES
(a) Record: Record by pressing the red floating action button. Find saved data stored in the folder icon.
(b) Export: Export data by selecting an option to send via e-mail or shared in Google Drive or Dropbox. Locally saved files can also be transferred from the folder icon.
(c) Sensor Information: Clicking on the (i) icon to identify sensor name, vendor, and current data collection rate, and to learn what kind of data is collected by the sensor, its physical operating principle, and links to additional resources.

SETTINGS
* Note that not all settings are available for all sensors.
(a) Data Display: View data in graphical, digital, or vector form.
(b) Graph Display: View multi-dimensional data sets on a single shared graph or in multiple individual graphs.
(c) Displayed Axis: For multi-dimensional data on a single shared graph, select total, x, y, and/or z-axis data.
(d) CSV Timestamp Format: Record clock time or elapsed time with sensor data.
(e) Line Width: Modify visual presentation of data with a Thin, Medium, or Thick line.
(f) Sensor Collection Rate: Set collection rate as Fastest, Game, UI, or Normal. The sensor collection rate is displayed for each option when selected.
(g) Keep the Screen On: Prevent the app from turning the screen off automatically.
(h) Calibrate: Calibrate selected sensors.

Ratings and reviews

Love this app, it let's me do so much with my phone! The color detector isn't letting me access it. UPDATE: You are correct! 2 weeks to fix. If there are any mechanics: I used this app to diagnose a bad coil-pack in my jeep using the magnetometer. I also think I may have discovered a fuel injector failing using the spectrogram. ELECTRICIANS: I used it in a cabin to find where they had current running so we could tap another recepticle, got to show my daughters Lenz law in action! Keep being U

Very cool app, love the VR magnetic field feature, even if it's a bit finicky. Update: Also love that the developers have continued to make meaningful additions to this app. The "challenges" is a neat little bit, nice way to let people dip their toes into this kind of stuff. It might be a good idea to give a bit more explanation of how the phone actually measures various things, as well as what exactly they measure. Update 2: Also love the meaningful release notes!

I've been using your app t for a longtime,and still enjoy the diff.vtjings that I can explore and quantify! My favorite is the spectrogram, I've discovered that sounds replicate the resonate shape of the thing that makes the sound,and even seen things that are invisible to the eye ,as they show up as an image in the screen ? Keep up the good work !
