Outdated app; dont download; iPhone gives message that app will slow down phone

This app hasnt been updated since 2014, which is always a bad sign. Either remove the app from the App Store or update it. When I opened the app today, I got a pop up message from APPLE saying the app is so out of date that if I open it my phone will slow to halt and hog up excessive memory.

Im about to delete the app, but wanted this review in before I did.

How hard can it be for you to update this app. Its now actually dangerous for people to have this app on their phone. DONT DOWNLOAD!!
