What app can I use to exit my iPhone without using my home button?

Well, my home button is starting to go crazy. A friend of mine told me I should download a.n app(she didn't know the app) that I could use to exit without my home button. It's like a thin bar appears at the bottom of the screen and when you slide it.bam! There goes the exit. I tried to search but here's what I found:
>A similar vid that was so outdated it's about "iHome" and stuff.plus, iHome isn't available in the app store.
>there's another one but it need jailbreaking. I don't want to.
>A very effective way but it would cause too much hassle(Power button, emergency call, back, passcode and voila!) I mean that's a lot of steps.

The only real way is to jailbreak it and get one of an assortment of apps that let you re assign other buttons say it you were to double tap the sleep button it could act as the home button make sure to get untethered if you choose to do this at this time Redsn0w offers the current version of software for free for an untethered jailbreak… You said you don't want to but this is the only way really cuz apps on apple app store don't have control of your device unless your in the app

Visit Apple store and get it repaired instead of downloading some app.
