Why is my iphone unable to purchase the free app, kik?

That doesn't make sense. You can't really purchase something unless you pay for it.

Anyways, there are infinite possibilities as to why it doesn't download. First, restart your phone. Hold the Home and Power buttons until it turns off. Let go. Wait for it turn back on and try again.

If that doesn't work, log out of your Apple ID and re log in. Try again.

If that still doesn't work, try to download the app on iTunes on your computer and then transfer it to your iPhone.

Cause android all the way!
