Answer 1

If you have access to an Android phone, you can profile your application using desktop Chrome's developer tools and a USB cable (very convenient).

Android and iPhone behave+perform similarly, but not identically. That said, for 90% of use cases, if you improve performance on Android, you'll see the same improvements on iPhone.

Hour for hour, at least for the first pass of profiling, I think you'll get better results on iPhone using chrome+android to profile than using a less rich toolset.

It'll require Chrome, an Android device able to run the android Chrome app, and a USB cable.

You have to install and use the ADB console command, but once its working, you'll have the full chrome developer tools interface available for debugging mobile.
