.ipa file

Greetings Amauri!

I am using BrowserStack to make screenshots for Google and APPLE stories. Google not a problem. The .ipa files is required to upload and test app but the generator creates a .pem and automatically creates the app in APPLE store. Works very nice but not possible to make screenshots. Is there a way to download actual .ipa for screenshots or is there another way to take many screenshots. I do not own the necessary devices for this.

Thanks! Brian
