Getting the idea This works. It produces a simple output as intended. I practiced to get the idea of tapping the screen to hold the signal. The time scale at the bottom was not recognized at first, but when I could read it, it allowed for measurements too. Screen capture was done by "Volume down and power" (Samsung). It's handy having such a great tool always available.
Really exciting! I am now not only using this for class, but also to see the wavelengths of different waves on the piano, what patterns different noises make, and other fun things I can do in my free time. I am glad it isn’t too complex, and I can use it in class and to just mess around.
Science Adventure Concise & succinctly accurate! I find this a perfect instrument for fine tuning my amplifier to ensure it reproduces all musical notes precisely.The only drawback is it cannot be calibrated to ensure it remains accurate.
Awesomeness A wonderful application for my needs. This is perfect for a small very Mobil device, and it works well. Also wanted to add just how much I appreciate you not asking for alot of permissions. Other app want access to everything it's unbelievable. Again, thank you!
My favorite app ever I am a science teacher and I used this this week to explain sound to my students. I can't stop humming scales at it, it's so much fun.
Extremely useful This thing can be used to check the AC signals in a circuit. Just attach a speaker and bring g your phone's microphone near it
Oscope is an Oscilloscope that displays audio waves taken from your microphone.
