5 stars: Even if you have zero use for this app, I recommend trying it if only to see some of the amazing capabilities of your mobile device's sensors, taken beyond raw readings, with both fundamental and advanced algorithmic processing. More advanced users might see the obvious functionality they desire for their projects.
4 stars: Pretty awesome. I would recommend adding some unit conversion though, like I was trying to look at the pressure in ATM but it only gave it in hPa so I had to throw it in my calculator to convert it. Seems like something that would be easy enough to program in.
5 stars: Excellent app. I find the sensors very useful for simple experiments. Not lab equipment but you get the general idea with very good results. Love the export capability.
5 stars: It is hard to believe that such a valuable, versatile, and well-organized app exists, never mind for free and without ads or other bloat. If I could suggest one improvement: I was very surprised that you can't view the spectra you've taken over time as \
5 stars: OMG I'm like a kid in a candy shop! Was only expecting some nifty eye candy representation of data.. Not a full blown toolset of epic little goodies. Echo location is bloody brilliant, reliable on my XZP upto about 30 meters. Do love the audio filters and tools you've added, Doppler and Correlation have come in useful. Thanks Dev, keep it up!
5 stars: A great physics thing. The problem is that, I haven't figured out how to utilis...
