It’s been mentioned before but is worth mentioning again. No need to use up your iPhone’s battery to set your alarm. You can use your iPad as your alarm clock now as Apple have ported over the same clock from the iPhone to the iPad. No need to download extra apps on your iPad.
You can now delete those old apps you have previously downloaded and don’t have to worry about those apps crashing over night. The in built alarm clock is here for the iPad.
