Ratings and reviews

Great tuner. Would be great if the dev would stop being a con artist though. I've paid for this 3 times now. It's clever, copy and pasting and renaming the app and then deleting the old version so that everyone starts clean on purchase history, every once in a while. Getting old bro. Last time I'm buying. The lazy developer welfare is running low.

Been using this app for years, very rarely the needle would freeze, but that could be my old phone playing up; otherwise, the app works really well, it has great features and it's very easy to use.
