"Excellent application. Makes it feel like my phone is a tricorder. So many useful functions. And as cellphones get more advanced it just keeps making this application more useful. Keep up the good work. Thanks."

"Excellent app, thanks. I would love it even more if it opened with the sensor/app I was using when I last closed it. Or perhaps there could be a set-up option to specify the default sensor/app."

"An amazing team and set of tools. I was a user of the lite version for a year, then upgraded, and haven`t looked back. I constantly find new ways of using tools like acoustic analysers or magnetometer (like showing students the magnetic field around our NMR spectrometers)! Great work."

"Terrific app, gives access to the raw data coming from all of the sensors. I last used it to detect the magnetic field fluctuations produced by a water meter while troubleshooting a Flume sensor - it produced an impressively clean signal. Some suggestions for the developers: 1) Make it more obvious when data is being recorded, like change the color of the record button or screen border (i.e., only red while actually recording). I lost some data a couple times because I thought it was recording when it wasn`t - it can be tricky see the screen in detail when collecting data sometimes. 2) When the app is re-opened, go back to the same sensor it was in previously. 3) Make an easy way to generate an FFT of data recorded from any channel - for the water meter, it would have been nice to be able to get a read of the frequency of the magnetometer data. This could also be useful as a tachometer for motors, etc."

"Needed to monitor acoustic noise. Calibrated by comparing to a MS10. Worked just fine to record and calibrate several hours of noise. Thanks for your good work!"

"Just some disturbing, the xyz parameters will warp line every time their numbers are too long and it shake the graph UI"

"Excellent app. As an engineer I`ve been using the free version of this app for a while for ``quick and dirty`` checks on all sorts of stuff both at work and at home. Lot`s of time the phones sensors are good enough to identify an issue with something without unpacking the real diagnostic equipment. A few examples: - accelerometer to identify imbalance of wheels operating at speed - Sound meter to identify bad motor mount in my car - light sensor to identify weaker than average light sources - tone generator is actually a pretty good function generator (sine, square, etc) Just found out about the paid version and bought it right away. Great job."

"I feel like I wasted my money on this app that doesn`t work on my phone. I`m sure it`s good on new devices but it`s like buying a set of new tires that don`t fit your car very well and you weren`t told the size of the tire."
