Bending, harp ninja

Hi. On h.ninja hole 3 I hit half step, and whole step. In the app but it sounds whinney. Same with hole 4 I can start to bend it down but it's Whinney. Is that a good beginning? I know bending is a journey. Trouble is I cannot compare with with my 4 draw pucker bend as it has a fat tone. So the ninja app is all I have to go by.

Also hole 4 often goes bend down, then no sound, I suspect I'm going past the bend. Although the tone is Whinney. 

Thanks
