It's annoying that text overlap in the app. It's there a fix for this?

I'm only using a sprinkler system to water St. Augustine grass on a .2 acres in South Florida. The entire area is flat and has the same soil make-up (loam). Direct sunlight shines mostly all day on every area other than a small 10'x40' strip on the west side of the house that is shaded part of the day. I have no trees and no plants. I have a Sprite controller and 1 whisperer sensor which is connected to the 3 zones that get the most sunlight. The learned % is at 55%

I don't see any benefit in using the whisperer. Thoughts?

Prior to installing a whisperer to my system, I set it up outside in direct sunlight for 5 days. When I try to add it to my Sprite, the light only blinks red once. I've tried multiple times to press the power button 6 times and it's still just flashing red just once. What am I doing wrong?

From the home screen, I use the manual watering option. Each one of my four zones won't go higher than 30 minutes each. I can go to the wheel adjustment, but it won't go higher for some reason and I'd like it to go to 60 minutes. 

I notice in the App, that there is a field called SQ  Feet. It's this info needed if im setting everything.
