Can i get my iphone cracked screen repared for free at the apple store?

My iphone 4 still works but my screen is cracked alot and you can feel the cracks when you put your thumb on the screen

Nothing is free.

You should get it done somewhere cheaper than the apple store there's alot of places that do it for a low price

No. Physical damage isn't covered by any warranty.

No. Not even if you have insurance. They will charge you about $125. Best bet is, if your phone is past the 1 year warranty, to fix it yourself or have someone fix it for cheaper if you can find someone like myself locally. I fix them for $70.
