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. 👍

What a pleasant experience ! Downloaded this after purchasing a "SNARKIE" - the little plastic tuner that snaps onto the head of guitars, mandolins , violins, etc. The instructions were clear, maybe, to a "P-H.-Dee in music theory. I got lost making judgement calls in setting the thing up I was unqualified for . There seemed no path to return to standard tuning for my brand new fiddle. The Noteworthy Tuner solved my dilemma as a novice. It opens quickly , is consistent in all phone mfg.'s.
