Many thanks to all that gave me their honest feedback about my app icon. The results are clear, I need in new icon! Thanks to @kalamera @pras2018 @imuz @anilkilic @divdev_ @mangooly @quinnzeda @BraydenTW @daronspence @girishw @Primer @zerotousers
I reached out to an designer on Fiverr with the first idea that comes in my head.
And here is the result:

The idea behind the icon:
Why two icons with a male and a woman?
If we look at my users, we can see that 75% are female. My assumption is that the respective genders are more likely to feel addressed when their own gender is shown on the icon. Is my assumption correct? I will test it!

Whats next?
I will do an A/B test and see if this icon performs better. I will share my results with you! I will also create other designs and have a graphic designer create them to find the best icon for my app.
What do you think? Is this new icon an improvement?
