pocketOscilloscope

i wanted to fill the ipad screen with just the scope no buttons . It said there was a bug fix but you still can't expand screen

Nice interface but there is a bug, At the bottom is a knob called rotation. The rest of the knobs move linearly very nicely but the rotation knob does not. You can rotate the two traces all over the place and yet that knob hardly moves at all. Also you can very easily rotate the traces completely in a 360 degree circle MANY TIMES, TOO MANY TIMES, when really one rotation is all that is needed. Because of this the rotation knob is much too sensitive. And finally another feature needs to be added to make this scope really useful and that is both horizontal and vertical measurement marker lines with math functions, so that PPV, Freq, Rise and Fall times can be measured. Most scopes have that function and that is what makes them very useful. Other then this, Nice Display.
