Failed the 15 minute test – Checklist Parent - Mom and Dad Family Calendar Planner and To Do Check Lists Review

I spent 15 minutes with it and couldn't figure it out so I deleted it. I wanted to add vinegar to a grocery list and couldn't do it. If I can't figure out an app quickly, it's gone. My iPad and my apps are supposed to make my life easier, not waste my time.
