URL for sending a user to the app review page on device's app store

Solution 1:

Update: iOS 4.2 seems to have fixed this and links now open the App Store app directly rather than the review page.

This article Dissecting iTunes links explains everything.

Heading straight to a review form

It’s also possible to send someone straight to the review form for an app.

https://userpub.itunes.apple.com/WebObjects/MZUserPublishing.woa/wa/addUserReview?id=337064413&type=Purple+Software

Simply replace the ID with your app’s ID to create a URL for your app.

On a desktop or laptop, this will take you directly to the review form in iTunes for the app or item. On an iPhone or iPod touch, this will open MobileSafari, then open iTunes or the App Store app on the reviews page, leaving the user only one tap away from writing a review.

To find out an item’s ID, right (Mac & PC) or control-click (Mac) on a link to the item in iTunes and select Copy Link. The result will look something like this.

http://itunes.apple.com/au/album/dig-your-own-hole/id19605549

http://itunes.apple.com/au/app/consume-mobile-isp-packages/id337064413?mt=8

The ID is the number in the URL after “id’.

It might be worth noting that this URL was created using iTunes 8. I don't think there’s a way to create review links in iTunes 9, so maybe this URL is being phased out. Use with caution.

Update: @mareMtl has provided an alternative review link for apps. Please note that it only works on iPhone OS devices.

Solution 2:

I tried a bunch of different links, this is only one working for me on iPhone AND iPad consistently:
