Lot’s of tuning and pitch options. Highly recommended. ### 5/5 — Great App! Mic not recognised after iOS 13 though. *2020-06-23* Features, visibility and general usability are very good on this. I cannot use it from iOS update 13 as the mic is no longer recognised. Any assistance would be appreciated, thanks. ### 5/5 — Privacy is King *2020-05-14* I won’t download an app unless it respects my privacy.

It works great, who cares if it fills the entire screen on my iPhone 11? There’s a lot out there, but this is always my go-to. Super simple and easy to use, it lets you know just how close or far off you are. Love the interface. Great work! I’ll be using this for years to come. ### 5/5 — Accurate *2019-09-11, version 2.4* As accurate as I’ve ever found. ### 5/5 — Tuning *2019-08-15, version 2.4* Simple lots of different tunings. ### 5/5 — Works Great *2019-05-29, version 2.4* An excellent tuner! ### 5/5 — Awesome *2019-05-28* I don’t usually leave reviews but this app is awesome. ### 5/5 — My personal favorite tuner *2019-03-25* I tried tons of apps for a good tuner and this one is my favorite.

I just learned about open tuning and of course this app supports that. I also just learned about playing 415hz, which this app supported me in learning more about and tuning into these different ways to play. Thanks for keeping it going. ### 5/5 — Great app *2025-10-10* Quick way to check tuning I use it to check trombone intonation also guitar ### 5/5 — Very useful *2025-09-13, version 2.4* The excellent design and performance of this app makes using it transparent. ### 5/5 — Great app!👍 *2024-07-31, version 2.4* Outstanding tuner. I would recommend it to any Guitarist 👍 ### 5/5 — All you need *2024-04-10* Love it! Pay $2.99 and be done with it. No annoying ad videos or pricey monthly subscriptions. This is all the guitar tuner you need. ### 5/5 — So worth a few bucks *2023-09-06* Way, way better than the alternatives, especially with respect to alternate tunings but even just for getting standard dialed to within a cent or two ### 5/5 — Good App With One Flaw *2021-10-06* This is a very good app but if you don’t remove it from memory after you done using it, it will drain your battery. ### 5/5 — GREAT TOOL *2021-09-26, version 2.4* Appreciate the app. Always tuned by ear, but getting older and tuning abilities a little off 😊. This is perfect for me! ### 5/5 — My best app *2021-03-13* Great app! The visual feedback is really useful and it is precise. ### 5/5 — Just buy it. *2021-03-08* Finally A quality tuner that lets you tune to the slightest degree even in a noisy room, without some lunatic nutjobs’ sick idea of “advertisement” popping up every three seconds to hinder your mad skills.
