App icon - it's more important than you think

A while ago I decided to take my app icon seriously, why?

The icon is the first graphical element which the users see
It needs to stand out versus other app icons around it while appearing on the search results for instance
It has a major impact on the decision making of the user to click on your app, and even continuing and downloading it, not to mention, open it later on.
It has an impact on whether or not to open it again / easily find it, when it is already installed on the user's phone

So I paid hundreds of dollars to a professional app icon designer in order to create the above mockups, and then implement a few of them.

Was I able to tell which one is more attractive than the other? No.
Not because I'm a tech guy with lame design skills, but because the potential users should, using the store listing A/B testing.
So here is the experiment video: https://www.youtube.com/watch?v=UohvqbwGuPA

The results were amazing, made a significant change overtime, and profoundly improved the ASO without any doubt.

Things to remember about A/B testing:

Keep on running the test patiently until you get significant amount of traffic data (by the thousands)
Don't be the judge. Keep on testing previous graphics VS new ones, as you don't know what will be the results.

Good luck!
