I’m not sure any of the charting apps used by air carriers are even available on another OS at this point. I’ve never been aware of JeppFD Pro on Android and I believe they dumped Windows as well.
There are other options of course but as far as I’m aware in the US it’s all iPads and JeppFD Pro. The feds are familiar with it and a regulatory framework is created around it so it’s the path of least resistance. And as a pilot, I’d say most of us are pretty satisfied with it.
