Can’t download – Battery Magic: Battery Life Battery Stats Battery Charge & Saver all in one! Review

I love this app, but now my phone won’t let me open it, it says that it needs to be updated, but it is not in my list of apps needing updated on my phone, and when I open the page in the App Store for it, it doesn’t even give me the option to open the app. I don’t know what I can do to fix this... problem
