Looking at the reviews, I see multiple people saying that the developer required paid users to write a review in order to unlock the ability to use the front camera. I think it goes without saying that is an incredibly scummy practice.
Oh, an app doing that to me would certainly get a review.
They have two app versions, a free with fewer features and a paid with full features. I personally tried first the free to make sure it works, and then I paid for the full version.
rating an app to unlock features is scummy? compared to all the other practices and anti-patterns apps use today?
Yes, it's still scummy. Bad practice doesn't make another bad practice good...
Yes, it's incredibly dishonest and encourages reviews which are likely to lead other people to make the same mistake. Any application which does so is against apples guidelines and ought to be banned
No need to write -- just click on a star rating. I clicked 3 stars for that reason. But it functionally is phenomenal. Will honestly probably change it and write an actual review...
