About me: software developer who is into JavaScript and NodeJS and constantly working on one or another side project and/or open source. I have a blog at https://alex-rudenko.com
Apple's recommendation is to avoid installing apps from untrusted sources. I guess due to their review process they believe that the apps in the App Store have no exploits. So the only exploitable thing is JavaScript.
Regarding Android, I guess you need to check with the particular vendor because there are many.
P.S. as far as I understood it, Spectre can only access the data of the current process (therefore, it's dangerous for browsers). I may be wrong about it and I have not found the exact answer yet.

P.P.S. Apple has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown My message is about Spectre.
Thanks!
So that's where the slowdowns in iOS came from! hahaha
