I'm trying to learn to write a mobile app in my spare time as a side project. I have 0 experience with mobile development.
Right now I mainly do migration and automation of applications to AWS and I have experience in C, Java and Ruby (though I'm rusty in both).
Are there any languages that can be used to develop cross platform applications? (iOS and Android) I know friends of mine who develop with swift at work, but it seems to be iOS specific.
Maybe I should just focus on one platform (possibly iOS) then migrate to android later? If I do develop cross platform, thoughts on HTML 5 and using something like PhoneGap?
Any help or direction would be appreciated, thanks. Sorry for the huge wall of text

E/ If it helps, a general overview of the app is to allow users to select a range of options, then based on those options return a selection of items that fit their selection.
