Yes, I remember the harmonics were an issue. We were excited when the iPhone came out and had the resources to tune all the strings at once. I can’t remember what we did, but we did provide sharp / flat indication. It definitely worked just like a normal tuner you would find, letting you dial it in quite precisely. Maybe I will crack open the code and look at it...
