Noone remembers your app exists after a few months, why did you expect anyone to give a damn about your product after two whole years?!
During that two year delay we made the iOS version a quality product instead of having our attention divided by another platform that delivers less than 10% of the userbase. It was the right move.
Your attitude is very common among iOS developers and it's the main reason why you only have 10% of userbase on Android - companies that actually understand their audience have no issues reaching wide users and profits on both platforms.
If you deliver a subpar submarketed product on App store you will fail. If you deliver a subpar submarketed product on Play Store you'll fail as well. It seems you did the second thing.
