This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps?

I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin.

Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps?

I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along.

So any cross platform developers out there? Do companies have different teams for different platforms?

Any insight would just help me get my head together. Hopefully this question makes sense.
