Is it possible that you are over thinking things a bit?
You should be able to get close enough by tuning for
maximum signal loudness, with a 700 Hz'ish sounding tone.
If the other guy keeps drifting up, or down, after you
stop sending, that might mean you are guessing wrongly...
I doubt anyone you work on CW will think less of you if
you are off frequency a smidge.

To be clear the reason I'm thinking of getting "The Magic Eye" is
that it eliminates zero beating via the sound of the tones. I have
been playing a sound file of 700 Hz from my iPhone and adjusting the
frequency until they zero beat. Depending on band conditions,
adjusting the volume and probably my hearing ability to get an exact
zero beat on an incoming CW signal is not always easy.
