UPDATE Now the app contains more keys with more to come. So I feel better about it now. It works well enough and I can recommend it. 5 stars when all keys in an octave are covered, meanwhile 4. ### 4/5 — Overblow *2018-01-15* justa want to know when to add overblow to this app **Developer response:** version 5.0 will be next week with Key of F and overblows/overdraws for all original kind od harmo ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t show bent note. *2021-07-11* I know the notes are bent but the display does not show it. ### 1/5 — Update made app useless *2020-10-18* The latest update made this wonderful app useless now when it shows you pick any key and it shows your Harmonica it does not show letters it does not show the notes it has three dots on the spaces above and below the indicated holes does not show any note symbols or any notes still works for the green red and yellow but just shows dots please fix this issue because I used to love this app **Developer response:** Sorry, but I was out for long time. This problem is actual? ### 1/5 — Does not work properly *2020-08-07, version 8.0* Do not buy ### 1/5 — Change tabs *2018-12-30* I can not convert the tabs to other keys. It always stay on tabs on the key of C. How do I change to the other keys ? This app doesn’t work **Developer response:** Click / tap ‚Key of C’ and choose and back ### 1/5 — A waste of money! *2017-05-24* It will show you how to bend if you have a C or D harmonica. **Developer response:** Current version (4.0) has key od C,D,A,G and E. Next version will have F. You may define you own kind. You may record your art ### 2/5 — Harmonica Tuner Pro *2017-10-16* I’m very disappointed. I paid $.99 for the lesser version. You’d think that amount would be credited toward the “Pro” version, but it’s not. Secondly, I guess I should have read the fine print before I paid an additional $3.99. Only 4 keys come predefined, C, D,A, and G. Supposedly more can be defined, but how to do so is unclear. If there is a customer contact, I’m going to ask for my money back. **Developer response:** now is key of C,D,A,G and E in the next version will be F and than Bb ... Probably in version 5.0 will be overblow. For sure version 5.0 will key of F and overblows/overdraws for all original harmos. Probably next week There will be release ### 3/5 — Keys are not change *2017-02-23, version 2.5* Where are other keys ### 4/5 — Nice but could be better *2024-06-20* I like very much the recording possibility but it lacks the possibility to store the files and to listen to them later. Could it be added ? **Developer response:** Hi. Thank you. but I am not sure if I see problem correctly... we have "record" button and afer we may shre file... ### 4/5 — Great tool but *2019-08-04* I bought this app yesterday and it worked fine. However, went back to it today and the different notes on the right hand side beneath the harmonica layout keep cycling through. When a note for the C harmonica comes up, the note lights up briefly. Disconcerting as I play because various notes light up that shouldn’t **Developer response:** You may try to change Sampling rate and Amplitude Rate in Settings ### 4/5 — Useful learning tool *2019-06-07* Newbie harmonica player. This program lets me “see” my bends, providing instant reinforcement when I’m moving in the right direction. The visual layout also helps me develop an intuitive sense of where the notes are. One big gripe: all of the notes are labeled as naturals or flats. There are no sharps! I know that G flat is the same tone as F sharp, but it’s awfully distressing to see it displayed that way. Especially for someone with a bit of music theory. How hard would it be to label the notes using standard notation? Or offer that as a display option, to toggle back and forth? **Developer response:** Thanks for issue. I thought that earlier but in app I must have clear values. Is it correct for you if in settings option to show only sharps or show only flats? ## Most praised reviews (10 highest-rated) ### 5/5 — Very useful app *2023-02-18* I’ve been using this app for over 1 1/2 years and still find it very useful. Sometimes I open it just to verify note locations for a specific harmonica key. Other times I am working on bends and the feedback is invaluable. The fact that you can define your own harmonica layout is an awesome addition for my custom harmonicas (and any keys the developer has not predefined). For the cost, this is one of my best IOS app purchases. Thank you! **Developer response:** Thank you for info! It's very motivating ### 5/5 — If you have a harmonica you need this app! *2022-12-12* Even if you don’t have one but are thinking of it you need this app! I really need this app! Great to check my playing and confirm tuning! **Developer response:** Thank you! try settings to more suit ### 5/5 — Ideal for harmonica players. *2022-12-02, version 8.0* Just what I was looking for. Thanks. Gives me confidence in my harmonica and my playing. :) ### 5/5 — C调二把位如何设置？ *2022-02-02* C调二把位如何设置？ **Developer response:** You may click on button "Key of C" and choose or define yourself ### 5/5 — App with great extra use ! *2021-09-08, version 8.0* It already does a very nice job right from the start; but then I used the builtin Editor (very easy) to create a "harmonica" with the notes of the major pentatonic scale only ... and this is tremendously useful in practicing this scale ! Fantastic, no other app allows this afaik ! Next will be a blues-scale-only "harmonica" :-) ### 5/5 — Perfektes Tool zum Üben *2021-02-21, version 8.0* Ich spiele seit 1,5 Jahren Mundharmonika und diese App hilft ungemein dabei die richtigen Noten beim Bending zu treffen. Einfach Übungen mit wechselnden Half und Whole Step Bends lassen sich wunderbar kontrollieren und bring sehr schnell Erfolge. Die App hilft dabei ein besser Spieler zu werden. Würde mehr dafür bezahlen! Bitte noch mehr Standard-Tunings im Low Bereich hinzufügen. ### 5/5 — Great to practice learning to bend! *2020-07-25* I appreciate how this app helps me see if I am hitting the correct notes and if I am making the bend. I like how easily I am able to switch harmonica keys to use with all my harps. Thank you for this handy tool. ### 5/5 — nice work *2019-06-08* it is a great app，please add chromatic harmonica ### 5/5 — Always crash on iOS 12.0 *2018-10-23* Always crash on iOS 12.0 even though reinstalled. **Developer response:** Version 6.0? ### 5/5 — 很实用的软件 *2018-05-21* 很不错的软件，在练习中对音准的校正很有帮助！ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
