How do I write a review from App store on the iPhone

You want to write a review for an App in the App store?

Or do you want to review the iPhone?

If you want to write a review for an App, find the App in the App store, open its details page, and then tap on Reviews, and then on Write a Review.

You must have bought or downloaded the App before you can write a review.

You'll have to use Safari on the phone or another device if you don't use a computer, open the Apple Store link at the bottom of the Apple page Apple.com/retail and choose the product you want to review. Scroll down to "Reviews" and look for the link "add a review". You will be taken to a log in with your Apple ID and password. After that you can write your review.

Read the Apple Recommended post, on the screen right after your original post.

Scroll this page to the top. Then scroll down until you see the post by Phil0124 and follow the instructions in it.

I just followed the instructions posted by Phil and I was able to write a review in the App Store.
