    It’s really easy to use and I love it! It’s not complicated like some of the other tuning apps are. I played violin for two years and I wasn’t able to tune it until I found this app today! I absolutely love this app! If you are reading this, you should really give this app a go. It’s easy to use. I mean.. REALLY easy to use! ⭐️⭐️⭐️⭐️⭐️
