Tune your instrument to any scale you can imagine. Perfect harmony, or super sharp dissonance, and everything in between. Accurately recreate traditional music from around the world, as well as pre-modern western music. Or use it as a standard instrument tuner! Each scale can be selected, and its notes can be played to get a feel for it before tuning your instrument. Each scale may have a different root note (1/1), and the root note frequency (1/1) can be adjusted while tuning. Entonal Tuner was created when the developer began to learn about Just Intonation and microtonal music. He soon found that it, although some tuning apps support different temperaments and scales, they are difficult to edit, and not a "first class citizen". So the seed was planted... and Entonal Tuner was born. ## Key features - Tune to any scale - Explore scales by playing notes - Adjust root note frequency - Recreate traditional music - Standard instrument tuner function ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Upgrade to Pro | $3.99 | one-time | ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/entonal-tuner/id1344007171/reviews.md ### 4/5 — Brilliant Design But Can’t Add Custom Intervals *2025-10-24* If this worked as promised, id give it six stars, but. . . when I try to add a custom interval to a saved scale it never appears. No way to contact the developer— the form submission doesn’t work. For the given scales, it’s great. ### 5/5 — Love the idea *2025-03-04* I will definitely buy the full version when it comes out. Planning on using it to help tune to A=432 24-tone Just intonation ### 4/5 — Upgrade to pro *2023-08-15* How do you upgrade to pro? in-app option doesn’t work. ### 3/5 — Much needed app but still needs work *2022-12-24* I was really happy to find this much needed app. I’ve been using Clear Tune but it’s cumbersome and limited to 12 note scales. Layout is simple and logical. I did encountered a problem with the playback several times. It seems that the software is misinterpreting ratios, which is quite frustrating. Some notes keep playing lower than they should based on the indicated ratio. Also some notes don’t show up in the tuner mode at all. I also want to suggest that you add the ability to reposition notes in a scale so that if one forgets or wants to add a note they can put it in the correct place. Lastly I tried leaving feedback through the app but ironically I got an error. Keep up the good work. This will easily become one of my favorite apps. ### 5/5 — Great Xenharmonic App *2020-11-03* I downloaded this for the Bohlen Pierce Scale, and I use it all the time for writing microtonal music. So far it’s the only thing on the app store that does what I want it to do, so thanks for making it. ### 5/5 — A great resource *2020-06-18* I was VERY happy to pay for this already awesome app - hope future editions can have a little more options for playback tones (sines and/or other more-sustained tones) and the option to play chords, as I’m interested in this app for flexible ear training more than for instrument tuning ### 5/5 — Perfect *2019-09-21* Just what I need to tune an instrument using Just Intonation instead of ET. Very good app! ## Frequently asked questions about Entonal Tuner ### What is Entonal Tuner used for?
