Way cool! My tuner app of choice used to be Clear tune, which is no longer available. A notice says it may no longer be supported by the author. I installed this one probably because of its Steampunk appearance, but it works so well that I'm about to remove the copy of Clear tune that I've side-loaded! I particularly like the fine-tuner at the top of the screen. And the option of a relatively inexpensive ad-free version.

Amazing. I'm hitting all the right keys, and this app shows that Or if I want to know which not an artist is hitting this app shows the same note

I've been using Carl Tune for years to tune guitars, Ukuleles and even a Piano or two. It remains the most awesome tool for tuning other than my Korg analog tuner. Long may your Big Jib Draw.

Wrong tuning. I have been a classical vocalist for the last 25-30 years, I know my tune. I am singing C it is showing A#, I am singing D it is showing F.... be very careful, especially if you are a classical singer it will train you to be permanently out of tune. Good try and good idea, but it does not do what it promises and even does the opposite which is harmful for a new musician.

Would be good except ads everywhere. Trust users to reward a good app don't make it ransomware. Not a good business model.
