Can iPhone apps be created for all Android/Smart phones?

[GN83]

I am creating a new app and am keen to understand if one app can be used on all smart phone's/androids or if different apps need to be designed for each?

Thanks

Strange but I strongly doubt that you are really creating a new app

If one knew enough to create a new app, one wouldn't need to ask a question like that. Very strange indeed!
