First go to Safari and type in the address bar mc.dkcraft.net:8123.
Then, click the button at the very top by the address bar that has an arrow on it.
Press Add to Home Screen.
Name it anything you'd like. (E.G. DKCraft Live Map)
Click on it's app on your screen.
It should not open safari, but it's own little app.
Enjoy!
