iOS had a huge head start over Android in the aviation market space. That has had consequences for the level of development targeted at the two operating systems.
Personally, my phone has been Android almost as long as Android phones have been around. But, I’m not a zealot. I bought an iPad 13+ years ago because it was the only game in town.
Since then, I have tried most every EFB in both OSes available in the US market. While there are definitely adequate Android EFBs, a few that are excellent, and a few that were great but could not be sustained, overall, the most feature-rich are still iOS, mostly because of preexisting market share. To me, it’s about the app and its capability for my missions, not the OS (in my case, it’s also about 13 years of familiarity).
Story. I have a friend who hates Apple. Wouldn’t even consider an iOS EFB. Used the one that is, I think, the first Android EFB for several years and was quite happy with in. Then, he and a buddy, did a trip from the west coast to the east. The buddy used ForeFlight. My friend bought an iPad when they got back.
