Review from David Young
Good amp!...enough said!
November 1, 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.
Great assortment of interesting tools that can be adapted for use in activities such as student science projects.
This app has many features that allows you to view the raw information produced by the phone's features and it was very useful on getting data for my physics lab
So well written and a great tool for the curious mind.
Highly recommended. I have tried many sensor toolbox apps and this is the best one I can find on Google play so far
This is a useful tool thst saves me time.
New Spectogram mode.
The app is now compatible with Chromebooks.
Added pause button to Oscilloscope mode.
Small performance enhancements while recording data.
