Interesting. Still playing with settings and learning functions. So far I'm impressed.
Great app! there are things to improve dough. the case/frame around the interface is a bit annoying. it'd be ok if it didn't use up effectively half of my screen area, the rest is a bit small as a result. could be fixed with a simple switch/check box in the settings. but the app works and i'm impressed.
Great idea, if only the phone were better equipped hardware Wildly inaccurate results but I wouldn't expect my phone to be accurate... with no less than three distinct microphones, which one does the app use? But, playing around with the settings for a bit, I finally at least got something other than 0.0m for a reading. Although, across multiple pings, I got results ranging from 0.2m to 15m, in a room no more than 5m long. I'll have to try with external speaker and mic...
Using a 1khz square wave, single pulse, continuous, and the echo window set between 1 and 3 meters, I can use the map graph to accurately measure the depth of my dresser without even getting out of bed! My roommates hate me. They're just jealous.
Not useful Top right time/dist display doesn't work at all. Tried changing various settings. No go.
Neat options, but you really need a band pass filter to get only your signal and filter out noise.
