Very Cool App No, it isn't perfect. But it's the best attempt I've seen to make a real sonar device from a cell phone. In 10 years maybe our phones will have the capacity to run a perfectly accurate sonar app. I love it when people find clever ways to implement the technologies on the phone. Thanks DICON!
I hate ads but I love you So I bought it! My phone has the mic and a speaker on the bottom right next to each other, and it works perfectly! Thank you Mr. The app creator!
excellent rare tool. I bought this amazing app for many tricks...but also for some studies around... well done fully featured UI. I like visually parsing and history comparision helping a lot to handle job in complex spaces. I bought full release to start amazing new kind average physics experiments with my becoming day by day smarterphone...thanks to yours and alike brainy apps..
Excellent app!!! Cool program that is fun to use and fairly accurate! SUGGESTION: Use the sensors in my Galaxy S4 to automatically calculate the current speed of sound based on the phone's built in humidity, temperature and barometric pressure sensors for an always accurate measurement in any room... ;)
Interesting I like unusual apps and this is one.
