Not really. It’s a very complicated, highly sophisticated piece of software written for native iOS. And the market is small. By rewriting it for Android, the only market share they could expect to get would be what they can steal from Garmin’s Android install base - which the Play store notes as “100K+” downloads. And we haven’t begun to consider the explosion of the hardware/software testing matrix.
The ipad operating range ends at 35C. That's ok for airliners, but in smaller aircraft with bubble or no canopies where the device can be exposed to sunlight, the temperature can exceed the limit.
For those use-cases alternatives to foreflight are probably good enough.
For cases where it matters and must be foreflight the price of the device (even apple taxed) doesn't matter at all compared to other cost.
Most popular OS, yeah right :(
