5/5Really great
This is like my first time ever actually reviewing a app but I gotta say after using guitar tuna for years I got sick of them trying to worm cash out of me for any tuning other than standard. And as someone who plays a lot of Drop tunings, along with my 7 and 8 string I couldn’t find an app that was free and actually accurate, until I found the LunaTuna, really this app is a great tuner and I’ve been using it exclusively since. No hoops or anything to jump through just a basic accurate tuning app which is just what I needed. Really great app, easy to use, accurate, versatile I couldn’t ask for anything else! 10/10! Keep it up!

5/5Very nice
I just got a kalimba and need to tune it, but have no idea what I’m doing. This app is the only one I came across that looks like it was made by a real person with real design skills, and has normal reviews from normal people. (Just like the old days of the App Store. RIP Apple.) So far I still don’t know what I’m doing, but the app is fun to use and look at, and extremely straightforward. No ads, no bloatware. Just great design and functionality. Thank you!🌹🎵

5/5The best tuner for musicians
I experiment with instruments where tuning is an issue: cello, winds, etc. This app is very pleasant to keep open while playing: it looks great, and because of the design I can keep an eye on my pitch while keeping it in the periphery of my vision. There’s enough customization to make it super useful, like dialing in the precision. Pretty, and useful.

5/5Straight forward tuner that doesn’t collect data
I love everything about this app. Simple and straight to the point. The developer’s response to feedback and issues has been excellent. Highly recommend!

5/5Beautiful and Simple Tuning App
If you’re looking for the perfect tuning app, this is it. Does exactly what it needs to and nothing more, tiny download, dead simple to use, doesn’t waste resources, yet manages to be beautiful. Minimal, elegant, and usable all at the same time.
