Yes unfortunately that's the case. I have developed computationally demanding apps for both platforms and always struggled during porting from iOS to Android trying to make them work roughly at the same level of performance. Android really requires faster hardware to run an app at the same speed as an iOS based device.
"The high performance apps are available on iOS. The close equivalent Android OS apps are best suited for home or maybe office, not professional use."
There are high performance apps available for Android OS. I never said there weren't any. I referring to the category of apps in my comment where there really aren't any.
