I am currently creating an iPhone app, and I'm almost done with the whole process.
One of the last features I'd like to add is for users to be able to review an object, rate it (on a scale of 1-5), and leave a short comment.
The only problem is that I've done everything to avoid a user having to create an account. I want to keep it as simple as possible, so whenever the user would launch the app, they wouldn't have to log in, there is no account creation and worrying about passwords, etc...
The only information that could actually interest me is what country the user comes from, but I don't need a username, an email or a picture.
Is it easier for the user to create an account or is there a realistic way of implementing a review system without one?
