Each time this topic comes up, these myths get brought out again.
Despite the number of times they are repeated, they just aren't true.
The DJI app can run just as well (or poorly) on devices of either operating system.
If the device is a modern one with a fast enough processor and enough RAM, it will run well.
On an older device with a slow processor and not enough RAM, the experience can be disappointing regardless of whether the device is Apple or Android.
The sticker on the box confuses many people.
It is not there to say that DJI equipment is made specially for, or runs better on Apple devices.
"Made for iPhone" is a developer marketing program from Apple that allows a developer to certify that their device/app meets certain criteria to work well with the Apple platform.
It doesn't mean that it doesn't work well with other platforms, it just means they worked directly with Apple to meet the MFi certification standards to work well with the iPhone.
