Great When It Works – System Monitor Ultimate Review

I've installed this app on an older iPad running iOS 10 and it works great. However, when I try to launch it on my slick new iPhone 6s Plus running iOS 9 .3 .3, it won't launch. Once it asked for access to my photos, which I granted, but it would never launch after that. I've uninstalled and reinstalled and no luck. When it works, it's an interesting app. It brings a deeper dive into data about everything from RAM usage to Battery consumption history. I just wish it would work and my primary device. For an app that is so good, not being able to use it on Apple's flagship phone with its current public OS seems to be a major problem.
