Useful for students and teachers in science, technology, engineering, and math (STEM) education and academic or industrial researchers, this app uses device sensor inputs to collect, record, and export data in comma separated value (csv) format through a shareable .csv file. Data can be plotted against elapsed time on a graph or displayed digitally. Users can export the data for further analysis in a spreadsheet or plotting tool. See for a variety of usage ideas for STEM education and publications from academia and industry.

A menu allows the user to sense or generate the following (dependent upon the user’s mobile device capabilities):

(1) G-Force Meter - ratio of Fn/Fg (x, y, z and total)
(2) Linear Accelerometer – acceleration (x, y, and z)
(3) Gyroscope - radial velocity (x, y, and z)
(4) Barometer - atmospheric pressure
(5) Proximeter - periodic motion
(6) Magnetometer - magnetic field intensity (x, y, z and total)
(7) GPS - latitude, longitude
(8) Inclinometer - yaw, roll, pitch
(9) Color Detector - detects HEX colors within a small circular area on the screen via the camera.
(10) Tone Detector - frequency and musical tone
(11) Oscilloscope (audio) - wave shape
(12) Spectrum Analyzer (audio) - graphical FFT

(13) Tone Generator – sound frequency producer

Simple and what I need

Leading a roller coaster physics day for summer camp and have been looking for applications that record total acceleration to calculate g-force and velocities all while phone is turned off (to pocket it while riding the coaster) and can be shared.
This is PERFECT.
May be a little awkward like going back and forth between starting accel. and vel. measurements and it appears the android version is a little nicer but just glad the app is available for both.

Great app!

This app is very cool, although I must add one complaint- why can’t I record and export the audio oscilloscope data? That was the primary reason for my interest in this app. It’s very cool that I can measure a sound wave so easily on my phone, but I would like to export the waveforms for post processing.

Developer Response ,

Thank you for the review. We are working on a solution for this.

Android version of this app is better, as usual.
