Review from Don Brainard
Great app. Nice features, well thought out.
November 15, 2017Thank you for the review.
Unuseful - e.g. sound meter measures about 40 db of sound pressure in a silent room with closed doors and windows. You should add a calibration function like in the g-meter tool, otherwise just a normal conversation is measured like a jet taking off or you have to subtract 25-30 db from the displayed value to have a more realistic information. For the other tools I don' t have enough expertise to have an opinion.
This is the perfect program to discover late at night, it has serious neat-o factor indeed.
So many features! I haven't checked accuracy yet. Multi record features are nice
I downloaded this app to collect gps data, but when I stop data collection it won't save a csv file, it does save a file for other sensors though, but I don't need those ones. Also I can not view the data or it's graph after it's been saved in the app, which is extremely annoying.
Great assortment of interesting tools that can be adapted for use in activities such as student science projects.
All working Very nice app btw. Mic and sound sensors are working now after device reboot. I tested my mic with sound recorder and nothing was heard, rebooted and all fine.
New Spectogram mode.
The app is now compatible with Chromebooks.
Added pause button to Oscilloscope mode.
Small performance enhancements while recording data.
