New problem. Need help.

I have loved this app for years. It is easily customizable and has easy data input. A week ago I changed the PEF increment value and lost the color blocks that indicate green, yellow and red zones. How do I get the zones back? My graph has a solid grey background.

Best one I have found so far

My asthma moved from mild to moderate and it was time for me to take it more seriously. I searched for an app to track my symptoms and this is the best one.

Highly customizable and helps me track my symptoms, test results and triggers. I pull up graphs to look for trends.

Please update the app!

I like that I can track multiple family members and my graph is showing the 3 zones. HOWEVER, 1) the graph for the children doesn't show the 3 zones, 2) I have to input a new pef high for each member of my family because they are different heights, 3) interface is spotty, I have to tap more than once, 4) some functions like pressing the pollen count makes the app clothes.

Since I paid for the app, it should work better. But if you're a concerned mom, it's not too helpful right now other than being a log. I'm a graph person.
