Do not get this, even if they make it FREE *2022-05-07* After you pay for the app, you have to create an account to use it, but a software glitch prevents account setup (can’t access Terms of Service in order to accept them, and accepting them without accessing them also fails). I’m getting a refund on this foul ball that struck out on three pitches. ### 1/5 — Cannot create account *2021-11-19* I downloaded the app I cannot create an account or contact customer service. Going to seek refund if not resolved ### 2/5 — Not very realistic *2020-01-20* It is good for new umpires to see more pitches. It is just very hard to judge where the zone is when animated. ### 5/5 — Great NEW tool for training umpires *2018-11-26* This looks like a great new tool for judging pitches in the zone. I’ve been looking for a tool to work on pitches low and away. The slot view is pretty good and sometimes the catcher or batter block the view like in real life. The Specific Zone Recognition gets into catcher framing (on or off) so that’s cool too. Might be cool if I could track my progress. Having all the pitchers to choose in Whole Zone is really cool though!! ## Frequently asked questions about uCALL for Umpires ### What is uCALL for Umpires? uCALL for Umpires is a sports simulation app that allows users to call balls and strikes from the perspective of a baseball umpire.
