In the tuner in the JG song app, are the lower and upper bars (arrow mark in pic) are half a note from the target note or it is not related. Just curious .
Thanks

I don’t know as I don’t use this tuner app.
However, I’m guessing you can answer your own question.
Tune your guitar string to one of the arrows. If the right arrow becomes F or the left arrow becomes Eb. Then yes, there is a semi tone between the marks.
Just to add confusion, there is 100 cents between semitones. In other words. The pitch between E and F would have 100 increments (cents) between the two tones. So you could tune your string @ + 5 cents. It would be 5% sharp going towards F.
Myself. I just look at getting the needle to say E exactly, if I can. How sharp or how flat when I’m tuning seems mostly irrelevant to me.

This won’t work as the app doesn’t show which tone you’re playing, only which one you should be playing (the E in the middle in the picture above) and wether you’re higher or lower in relation to that tone. If you tune your guitar to the left or right big line, there won’t be all of a sudden an Eb or F popping up on the screen.
As for the original question: I don’t know the answer, sorry

Hum, well, that is a unique app then. Thanks for the correction Els.
Pradeep, unless someone knows your answer, I suppose the best yer gonna get is tune to that E and just know your not sharp or flat. Seems that’s the info it will provide you. Which should be sufficient I suppose.
fwiw, there are other apps out there. I got one on my phone that’s free. It’s call pro guitar tuner. It seems to work ok. At least it works as I described and just ‘thought’ that your tuner would do. I apologize for my bad info.
If ya really gotta know, perhaps a different tuner would be in order.
Them snark tuners are pretty cheap and have worked for me for years. ymmv
