Oscilloscope

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.

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

As soon as I opened this app, it began detecting a noise outside my home. Very accurate and perfect

Ads are annoying, but other than that this app is really cool, simple, and fun to try out especially if you are a professional musician.

This game was like shoving poop back up your but and pee up your peepee

I would give it five stars but the ads ruin the look, if there was a paid version for a buck I'd gladly cough up.

Wanderful! Just use old headphone/mic cord as a probe. You can add voltage attenuation before entering the phone. Thanks.

I'm a automotive tech, thinking of all the ways I can apply this to my work and electrical testing.THANK YOU

Works good. Now have to create frequency divider for high freq input

Kinda useless for everything else..

Why a double trace "oscilloscope" when both traces are always the same? Also, has no controls, e.g. timebase, amplitude. What's the point of it?

I expected to see higher frequency display. Nice conversation piece any way. Keep up the good work. ..

it's not showing correctly a synth wave(tri;saw;square) but I guess it's because it's not plugged directly

Reserved for now will try using it with 30 channel graphic eq and measurement microphone.

It does exactly what it is suppose to do. Works great.

I love this alot thank you for this best app I had

Can't change timebase and no vert scale. Others are better

Nice...Don't know if it play's back though...

I'm glad that some one did this... thanks a lot to the creator...

Very nice app. Can be used to teach my students without need of actual cro instrument. Really superb idea of inventer.

- no way to get rid of them

Thanks, it is a wonderful app!

Works well need to check for saving n sharing features

This app should have voltage ,time and frequency scales

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.

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.

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!

I shall use this for demonstrating oscilloscope waveforms to science students. On Galaxy Tab 2 how do I reduce the gain even further than the minimum?

No displacement/voltage calibration? I can see that it might be tough to do, but it would be nice.

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.

This app is very good for engineers like myself. It would be terrific if there were a probe attachment through headphone input or mini-usb. You could use it for fault finding,although the voltage it could handle would be between 0-4 volts. Very Good.

I teach high school instrumental music. My students are both fascinated by what they see and how it connects to what they hear. My flute students especially learn about making a rich sound.

Would pay for a no ad version, afraid of inappropriate ads.

How about make the horizontal sweep settable to audio rates +/- 0.01 Hz, leave the vertical input from the mic and then I can tune my piano with a Lissajous circle?

It does everything it should simply and effectively. It also looks good. Maybe a scale for amplitude would help.

Sensitivity is perfect I think this app will be perfect for my application. Thanks. Only question is how accurate it is it will be compared side by side a real oscilloscope for accuracy.

It does exactly what it is suppose to do. Works great.

Great. Exactly what i was looking for. Easy to use.

how can i provide input signal for twochannels? one channel can be usedby microphone input, how to use second channel?

really very sensitive & usefull.I like it....
