About this app

Noteworthy Tuner is is an open-source tuner that makes it super simple to quickly and accurately tune virtually any instrument. Just open the app and play a tone, and you're already tuning.

As with all of my apps, the core feature set will always be free, and there will never be any ads.

Features:

• Chromatic instrument tuner for: guitar, ukulele (uke), violin, viola, cello, bass, and any other instrument
• Simple to use
• Detects note automatically in real-time (no need to pick the note first)
• Chromatic (not just some specific notes, but all 12 pitches in the octave)
• A4 frequency can be changed from 440 Hz to anything else.
• Both free and ad free (no ads!)
• Open source

Simple, lightweight, elegant, open-source (no funny data collection, I checked), and ad-free. I've used a number of tuning apps and this one takes the cake. The active frequency readout lets you tune much more precisely than other apps that try to be cute about it (I'm looking at you Pano Tuner), and the design is instrument-independent – No-hard locking to expected frequencies means you can tune any instrument with it. Protip: Touch the body of the phone to the body of your instrument for a better frequency reading if you are in a place with a lot of background noise.

Awesome. No other word for it. I have some basic coding knowledge, including Linux, so I am aware just how tricky it is to create an app like this, that works in real-time with the microphone. Plus, as there are hundreds of different Android devices out there, that just adds to the complexity. Using this on my Moto G7 Play, it works perfectly w/tuning my Clarinet. THANK YOU for not placing ads in this, even though that costed you money undoubtedly. But as a consumer I attest that it's sweet. 👍

Creating a good tuner app is challenging. The trickiest part is getting it to average out the waveforms of various instruments so the indicator moves smoothly, and stays in one place long enough, for a human to use it. If it updates too frequently, it's just frustrating, because you can't adjust your tuning to keep up with it. In this respect, I found this app better than some, but not as good as others. It may work better for you, depending on how you use it—so it's worth a try.

Thanks for this thoughtful feedback! I can't tell which direction you're suggesting I'm off of that ideal balance: do you feel it should be more responsive or more stable? I balanced it carefully to work well for me when tuning my guitar, but I'm quite open to trying adjustments. (I could also possibly make it configurable.) Thanks!
