Hey everyone, A few weeks ago I launched Fine Tuner, a minimalistic tuner for iOS 7.0+ that utilizes your devices built in microphone. You can check it out here: https://itunes.apple.com/us/app/id877102884 Here's a quick demo video. The video is from the initial version of the app so it doesn't show features added in an update such as auto mode / tuning different instruments. The app is completely free for standard guitar tuning but if your would like access to additional tunings (30+ guitar tunings at the moment) and instruments such as bass, banjo and ukulele, there is a single in-app purchase of 1.99$ that unlocks everything. There are no ads in the app. I've also attached a few screenshots. I'd love to hear your feedback!
