Angry [Q] IOS development HELP

hello to you all.

I have a few questions regarding the development of ios app. I have no knowledge of this, I do know how I want the final product.

Now I know not all that I ask is probably legal, but this is of course only question

Is it possible to combine several different apps available in the appstore for a common app

app should in theory not be sold, but only serves to make my life easier. so must the app not going to lie down in the app store

Should the device (iPad) jailbreakes for this to be done?

the developer must be present in order to be able to program, or it can be done far away from me. We're talking about apps that are made for home automation.

can anyone help with a bit her tongue in my thoughts?

it would be super cool if there was someone who had the time and energy to look at my plans and see if it was realistic?
