Sine wave is nice and clean, can see a little bit or capacitance on the triangle wave and this capacitance is rather obvious on the square wave also. Problem more than likely is my phone hardware (Capacitor resistor network on audio output), but hey, for a free app you can't complain!

No decimals.... LOL useless!!

Most importantly doesn't require any permissions. Awesome.

I may be slow, but what is used for the output.

Only functions that work are square and triangle.

Checked it on the Rigol 1052e also with FFT. The sine waves are ~ flat ~ 20Hz-17kHz ; frequency is stable then drops quickly. Some waveforms generate small spurs 3-4x the fundamental about - 30dB. The triangle wave distorts above 1kHz and the square has a lot of ringing. Other functions work as expected within the above limitations and the constraints of the menu items [ e.g. sweep rate or mo

It would be very nice if the resulting waveform was displayed Ola

Not working with galaxy S4. Otherwise good app.

No permissions and a good program. well done.

HTC one. Sine wave does not work. Also needs proper popups for value entry instead of text box

DONE WITH MY TEK 200MHz OSCILLOSCOPE, WITH A 100 OHM LOAD ON PHONE OUTS... I AM USING A NEXUS7 32G TABLET. 1. GREAT SIGNALS, SINE VERY CLEAN ALL THE WAY, TRANGLE AND SQUARE DEPEND ON SAMPLING RATE. FINE UP TO 6KHZ, THEN THEY ROUND OFF. LOGICAL. 2. LIKE THE LOG SWEEP OPTION AND OTHERS, LOVE TO DO LONG SWEEPS TO CHECK STANDING ROOM WAVES. 3. Wish the keyboard did not pop up all the time... 4. Wish i
