A440 Tuner is a simple app for musicians who prefer to tune by ear to a reference Concert A (440Hz). Choose between a recording of a real oboe or a synthesizer oboe. This app is not a meter or strobe or chromatic tuner - it simply produces the Concert A reference pitch. While this may seem limited from the viewpoint of one who usually tunes by meter, it fits the needs precisely for musicians who are trained to tune their instruments by ear from a reference pitch. The oboe was chosen for this app because in an orchestra setting it is typically the oboe that gives the reference pitch at the beginning of rehearsals and concerts. ## Key features - Concert A (440Hz) reference pitch - Oboe sound options (real recording or synth) - Ear training tool - Simple interface ## Recent user reviews (10 of 21) All indexed reviews: https://appshunter.io/ios/app/a440-tuner/id304862860/reviews.md ### 2/5 — Ads and trackers *2023-11-29, version 2.2.1* An app for a dead-simple task; why must it have adds and tracking code? Time to find my tuning fork. ### 3/5 — Offer a remove ads option *2021-05-30, version 2.1* Hey, the app works but I have 2 requests 1 Please allow us to decide if we want the app to work with silent mode or not 2 I’d gladly pay you a small fee to remove the ads. Please add the option. ### 5/5 — This app is great *2020-08-16, version 2.1* To everyone saying you can’t hear sound it’s because you need to have your notifications sounds on. ### 1/5 — Dud *2019-09-26, version 2.1* Doesn’t do anything. I turned my audio up all the way and nothing. 👎🏽 ### 1/5 — Didn’t work *2018-07-06, version 2.1* I pressed both buttons in the app but there was no sound. I checked my volume and restarted the app—same results. ### 5/5 — Thank you *2017-07-14, version 2.0* Thank you for rewriting this app! It was always my favorite tuning app. So simple and easy to use. ### 4/5 — Needs update: *2017-05-24, version 0* Used to be good - BUT: 1. Crashes on launch (iPhone SE, IOS 10.3.1) 2. Needs update for 64-bit before next IOS version. Please. ### 1/5 — Does this work with IOS 9.1 *2015-10-26, version 0* Does not seem to work with IOS 9.1. Worked well before, and quite accurate when checking it with some professional grade strobe tuners. A useful app, it would be a pity to lose it. ### 5/5 — Just what I needed *2009-12-13, version 0* Thanks! ### 3/5 — Multi Instrumentalist *2009-07-14, version 0* This is a great idea, true, and especially for free. My only complaint is why is there vibrato on the oboe tone? Doesn't that defeat the purpose if it's not a straight 440? The synth tone is solid however, nice app for free. ## Frequently asked questions about A440 Tuner ### What is A440 Tuner used for? A440 Tuner provides a reference Concert A (440Hz) pitch.
