Unable to install app from App Store on iPhone

Re: Unable to install app from App Store on iPhone

Check you are signed in on your iPhone with the same Apple ID you use in the App Store:

Sign in to your Apple Account - Apple Support

Check you are using the newest compatible iOS Version: Eg: Look in Settings > General > Software Update

If an update or upgrade is available, it is wise to back-up your data before installing it.

Check if any restrictions are set:

Apple requires you have a payment method listed in your account for the first time you use the App Store or iTunes, even you only download free items:

If needed: check which payment methods Apple can accept in your country or region:

See: Payment methods that you can use with your Apple Account - Apple Support

and

If you still need help:

Apple support also have a trouble-shooting article online:

The App Store is currently down for a lot of users, and there are many systems down on Apple’s system status. Keep an eye on that and try again later.

Many reports of App Store issues being reported, so may be an outage that will be resolved shortly. Currently the System Status page does not show a problem with the App Store, but does show a problem with Subscription Purchase. Check here for updates.

To me it looks like there are various server related issues. Try again later when they have cleared.

The outage is resolved, and the App Store is working again.
