Cant see list items

I used this app for years and really liked it! I bought the upgraded edition, which is rare for me. My problem is the graphics. As my eyesight gets worse due to my age (40s), I found I couldnt see the list well and there was no way to enlarge it. The list choices are small, thin, and light in color. The wood with black chalkboard look has an attractive side, but doesnt have enough contrast. Got a new phone and tried a new grocery list app that I like much better (AnyList).
