How do you rate a iOS app review as helpful or unhelpful?

It is a little tricky. You have to press and hold on a review and then you'll see a popup where you can rate it as helpful or not helpful. But it seems that on iOS the trick is to press and hold on a review while it is part of the list. If you first tap on a view to read it, then pressing and holding does nothing.

As soon as you tap on "show all" the ability to rate a review goes bye-bye. This bug is completely new beginning with iOS 16. Previous versions of the operating system did not do this.

Ah. I see that.

Overtime, fewer reviews will be rated as helpful or not helpful, this degrades the value of the reviewing system.

The reviewing system doesn't have any value. Scam app regularly abuse it at scale. Apps that aren't scams can be materially harmed by even a few invalid reviews. It is a form of "engagement" - i.e. social media. But like any social media, it isn't real.

Here is a User Tip I wrote about How to spot fake apps, junk apps, scam apps and abandoned apps.

That is very much a meta-user tip. I'm like you are. I'm trying to inject some truth and reason into a larger social media system. But that's impossible. It simply can't be done by a single person. There is a way to find the truth, but reviews won't get you there.

Its possible its a persons job to review the reviews… that or the algorithm scans combinations of words and decides. Cant overlook the Star Rating either haha
