What brings this app down, however, is that it does not retain settings after closing and does app does not reorient when the device is turned sideways or upside down. ### 4/5 — Excellent, but *2024-06-20* The ability to tune multiple instruments at once and pin point the frequencies of sound we would not normally be able to discern as pitches is incredible. What brings this app down, however, is that it does not retain settings after closing and the tuning reference is not precise enough. ### 3/5 — 設定の保存はできないの？ *2024-05-16* チューナーとしては普段使いにしたいところなのですが、起動のたびに440から442に変更しなければならないのが残念。 毎回あの小さなスライダーで442に変更するのは非常にストレス。 買い切りとはいえ有料なので、せめて前回閉じた時の設定を記憶してて欲しいのですが。。。 ### 4/5 — Pour ceux et celles qui s’intéressent aux aspects subtils d’un accordage. *2024-02-28* Une application qui sort des sentiers battus avec une ouverture sur le monde des harmoniques. Dommage que sur iPhone il faille parfois éteindre et rallumer son téléphone pour débloquer l’app. Cela dit le problème ne vient pas forcément de l’app car cela m’arrive aussi avec d’autres outils. Hâte de voir arriver la version 3.0 annoncée déjà en mars dernier !!! ### 3/5 — Has difficulty detecting pitches *2024-02-15* I like the concept and sisplay modes, but in practice it seems to not “hear” or detect very well especially with guitar or uke when there is a little background sound. In fairness, other iOS tuners seem to struggle with this as well. ### 4/5 — Proposition question ambition *2023-03-11* Y aurait il, avec options, possibilités du choix de gamme pythagoricienne ou tempérée, recalculant simplement les octaves sur proposition de l’entrée d’une fréquence fondamentale au choix de l’utilisateur ? ( de zéro hertz à 25 Kilo …) Dans tous les cas, un grand MERCI **Developer response:** Bonjour, oui nous travaillons, entre autres, à ce genre de chose (tempéraments divers, avec choix de la note de référence) pour la version 3.0 en cours de développement ! ;-) ### 3/5 — 基準ピッチのバグ？ *2022-11-04* 設定画面で基準ピッチ(Tuning Ref)を変更しても表示の数字がずっと440Hzのまま。別のチューナーソフトから同じ基準ピッチの基準音を出して確認してみたところ内部的には設定した基準ピッチになっているようです。 複数の音程が混在した音を同時にピッチ分析できるので重宝します。 Auto detectの表示が周波数でなくcent表示できるモード、ソノグラム(スペクトログラム)表示モード、録音再生機能があると楽器練習により役立ちそうです。 **Developer response:** Hi damedame12345, thank you for your report. We hope you will pleased to know that the visual reference pitch has been fixed in 2.3.5! Thank you also for your suggestions : autodetect in cents, record feature and spectrogram (the latter being already in the desktop version). ### 3/5 — Partly functional *2022-08-26, version 2.3.3* The application has had a previous issue with the tuner’s auto-detection mode, but it is now fixed. However, the application’s visual layout is broken on iPhone 12. Aside from this, it is one of the most interesting sound visualization applications for musicians. It is great if you want to explore harmony in a more mathematical way — it very intuitively shows you how the frequency ratios between notes take shape. It also works great as a precise tuner. ### 5/5 — Updated!!! Completely functional again… *2022-08-25* Ok, I downloaded there recent update and everything is working again! Thank you. This is a great audio app for tuning guitar and also nice to let it listen to a song and show you the fundamental bass notes, or on a solo instrument, each note. Also kind useful for pitch training and developing your ‘ear’. Good work IRCAM. ### 5/5 — The most awesome tuning and analysis app *2022-08-25* Used it for years. Was bummed out when it stopped working on recent versions of iOS but they finally fixed it. It’s a brilliantly clever way to view frequencies as you can see the harmonics of your instrument or voice as well. It’s also available as a VST plugin and I use it with Gig Performer to tune my guitar during a show. **Developer response:** Hi Dhjdhj, the compatibility issue with recent versions of iOS has been fixed (in June 2022, since version 2.3.0). We hope you will enjoy The Snail again! ### 4/5 — Crashes on launch *2022-08-25, version 2.3.3* It’s a shame because this used to be my go-to tuner. I’ve uninstalled/reinstalled several times but it just keeps crashing. UPDATE: latest update seems to have fixed this. All good now. ### 5/5 — Compatibility issues addressed! *2022-08-24* Yay! It works again! **Developer response:** Dear Kezzism, we are truly sorry for the inconvenience and the delay in addressing the issue, but please note that The Snail is now back on track, with bug fixes and new features and improvements! We hope you will enjoy our app again. ### 5/5 — With latest update this tuner is excellent *2022-08-24* Now that it is fully functional on iOS 15 it is once again my favorite tuner. **Developer response:** Dear Joe, we are sincerely sorry for the inconvenience and the delay in addressing it, but please note that The Snail is now back on track, with bug fixes and new features and improvements! We do hope you will enjoy it again. ### 5/5 — Great, the best! *2022-08-11* Love this app, IOS 15 update! 😘 ### 2/5 — バージョン2.3.3でようやく起動可能になるも *2022-07-21* バックグラウンドでカメラにアクセスされて何か撮っているのが非常に気掛かり。一体何を収集しているのだろう。カメラのアクセスなど本来なら全く目的外で不要だろう。 **Developer response:** Hi, we are surprised by your comment as The Snail is a sound analyzer app and doesn't collect anything from the camera! Do you see the camera switching on as you launch the Snail?.. You may leave a message on this forum: https://discussion.forum.ircam.fr/c/the-snail/264 ### 5/5 — THE SNAIL IS BACK *2022-07-16, version 2.3.2* AW YEA THE BEST APP ON THE APP STORE IS BACK!!! Thank you all for fixing it!!! ### 4/5 — Darstellung auf iPhone *2022-06-24* Sehr gute App! Leider rastet in der derzeitigen Version die Darstellung der Tonhöhe ein und stellt damit, anders als bisher auf dem iPhone die Abweichungen der Tonhöhen nicht da. Als Option vielleicht hilfreich, ohne Alternative allerdings nicht erfreulich. Auf den iPad funktioniert bei mir alles, wie bisher (landscape Darstellung fehlt ein wenig?!) ### 5/5 — God bless *2022-06-23* finally compatible with iOS 15, let‘s hope it doesn‘t take that long next time **Developer response:** Hi! Thank you for your comment, and we are making sure The Snail is maintained at a faster pace from now on 😉 ### 5/5 — Fantastisch - und endlich wieder kompatibel! *2022-06-22* Dies ist die beste Tuning-App, die ich je hatte (funktioniert selbst mit polyphonem Material) - und nach gefühlt ewig langem Warten (seit 2 iOS-Versionen) nun endlich unter iOS15 verwendbar. Danke!! **Developer response:** Bitte schön!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Abzocke *2022-06-16* Gerade die App gekauft und bezahlt. Leider lässt sich die App nicht öffnen!! **Developer response:** Wir entschuldigen uns für diese Unannehmlichkeiten, aber jetzt (seit Version 2.3.0) ist die App mit iOS15 kompatibel 😉 ### 1/5 — iOS 15.4 *2022-05-20, version 2.2.5* Snail doesn’t work at all on iOS 15, such a good tuner I want to be able to use it! ### 1/5 — do NOT buy this SNAIL *2022-05-15* the SNAIL is incompatible with my device shame on the SNAIL Pierre Boulez is turning in his grave I was looking forward to using the SNAIL but my hopes have been salted the SNAIL is dead long live the SNAIL **Developer response:** We are really sorry for the inconvenience and the delay in addressing the bug, but please note that now The Snail is back on track! (So PB may now rest in peace, after all...) And The Snail is now maintained and developed at a faster pace. See this for more details: https://forum.ircam.fr/article/detail/the-snail-update-for-macoswindowsios/ ### 1/5 — 起動しない！ *2022-01-30* 購入したが、起動しないので返金して下さい。 ios15 で動作確認が取れないのであれば、最初から教えてください。 **Developer response:** Really sorry for this inconvenience! Everything is fixed now and you may fully enjoy The Snail on iOS15 again. We hope you will have a great experience with it. ### 1/5 — Décevant *2021-12-05* L’app ne fonctionne pas sur un iPhone avec les dernières mises à jour même après redémarrage. J’ai payé pour un app qui ne s’ouvre même pas. C’est de l’arnaque **Developer response:** Bonjour, vous avez tout à fait raison, et toutes nos excuses pour avoir tardé à régler ce sérieux problème de compatibilité avec iOS. Tout cela est cependant corrigé et nous sommes à présent beaucoup plus réactifs dans le suivi et les évolutions du Snail. Nous vous en souhaitons un heureux usage ! ### 1/5 — 5 Sterne wenn sie wieder läuft *2021-12-04* Leider läuft sie nicht mehr unter iOS 15 **Developer response:** Hallo NamBar, ja The Snail läuft wieder unter iOS15! Wir entschuldigen uns für die Unannehmlichkeiten und hoffen, dass sie Ihnen wieder gefallen wird. ### 1/5 — Crashes on my Iphone 11MaxPro *2021-11-07* … newest IOS installed. It does not start at all. Unfortunately. **Developer response:** Dear Mr Geiger, there was indeed a iOS15 compatibility issue and we are really sorry for this. But now, since version 2.3.0, The Snail should work as expected on your device! 😉 ### 1/5 — Please update *2021-10-16* This App not working on iOS15 **Developer response:** Hi Rezeik, we are really sorry for this iOS compatibility issue, and we hope you'll be pleased to see that The Snail is now fully functional again! 😉 ### 1/5 — Doesn’t work with my iPhone 7 / iOS 15 *2021-10-08* It just starts then exits. I’ll try to get a refund **Developer response:** Dear Marslander, there was indeed a problem with iOS15 and we are sincerely sorry it took so long to fix. But with version 2.3 The Snail should now work just fine on your device! We hope you will enjoy the app. ### 1/5 — Used To Be Great *2021-10-03* This was an amazing app. Very unique and very useful. Now it crashes immediately on launch in ios 15. Sad.... **Developer response:** Hi Irekord, thank you for the good words on our app, and we are truly sorry it took us so long to fix the iOS15 issue. 😳 With the latest version (2.3) you should be able to enjoy it again! ## Most praised reviews (10 highest-rated) ### 5/5 — The Snail *2026-01-27* I use this app as well as the plugin on everything I do. Anyone I’ve shown it to has also immediately downloaded this tool. Fantastic tool, good job. ### 5/5 — 和音も倍音も目で見える！ *2025-10-13* 最高のアプリ。 耳コピにも、チューニングにも、演奏にも、いろんな音が可視化されるのがとても楽しい。そして使い易く便利。 カリンバやウクレレのチューニングや和音の耳コピに使ってます。最高のアプリ。開発してくれてありがとう！ The best app. It's very fun to visualize various sounds for ear training, tuning, and playing. And it's easy to use and convenient. I use it for tuning my kalimba and ukulele, and for ear training chords. The best app. Thank you for developing it! ### 5/5 — リクエスト *2024-02-04* Bluetooth MIDI 入力の対応と、タッチパネルの最大発音数を増やしてほしいです。 ### 5/5 — « Boulez Tuner » dans la poche ! *2023-01-09* Ha mais merci, c’est beau, c’est à des années lumières du reste, c’est extrêmement ludique pour tous ceux qui n’ont pas l’oreille absolue, et c’est gratuit. Merci l’Ircam, continuez, c’est une parfaite mise en pratique de recherche appliquée pour le grand public et les musiciens. **Developer response:** Merci beaucoup pour votre élogieux retour, douddd ! Oreille absolue ou non (ce qui renvoie à la fréquence fondamentale d'une note), The Snail apporte une vision musicale et introspective du son dans toute sa richesse spectrale. Bonne utilisation ! ### 5/5 — iPadOS 15 compatible? *2022-11-09, version 2.3.4* Crashes on load on my iPad Pro running iPadOS 15. Update: Latest version works fine. Great for singing practice as also see harmonics. Let’s hope any iOS change driven updates are prompt in future. ### 5/5 — Application unique en son genre ! *2022-11-04* Les informations sur le spectre harmonique sont parfois cruciales pour comprendre certains problèmes d’accord qui sont parfois liés à l’importance et la stabilité de certaines harmoniques. Cette application m’a appris beaucoup de choses très utiles. C’est dommage que le clavier se superpose au menu des réglages (quand on veut changer le diapason par exemple) mais sinon l’interface est très claire. (Màj: Je me rends compte qu’il y a un bug avec le changement de diapason qui ne fonctionne pas toujours et des réglages qui ne sont pas stables, dès qu’on passe à une autre application. Dommage…) **Developer response:** Bonjour Cybermowgli, merci pour vos commentaires. Nous venons de publier 2.3.5 avec un nouveau mode de choix de diapason qui, nous l'espérons, conviendra : il s'agit d'un slider (légèrement logarithmique) qui va de 392hz à 450Hz. Des petites barres permettent de se caler visuellement sur les diapasons les plus pratiqués : 415, 430, 432, 440, 442, 444. Nous avons au passage aussi corrigé le bug d'affichage de la valeur courante du diapason! ;-) ### 5/5 — Work perfectly with IOS 16 *2022-09-22* Great app the update is now better than in the past 😉 **Developer response:** Merci NicolasMBP, c'est vrai que cela a pris plus de temps que prévu ! Nous allons être plus vigilants et réactifs à l'avenir (en témoignent les 4 mises à jours 2.3.x en l'espace d'un mois !) ### 5/5 — De nouveau fonctionnelle ! Merci aux devs ! *2022-09-03* Super appli, de nouveau utilisable, nickel 👌🏻 **Developer response:** Merci de votre retour !! (et de votre patience...) ### 5/5 — Snail works again on iPad OS! *2022-08-29* This is the only tuner I know of which can be used as an exploratory tool. The combination of a sensitive visual representation of pitch and a useful level of spectral analysis allows us to focus on timbre, which is notoriously difficult to evaluate objectively. That’s both because we are so close to the sound source, and because our experience of the sound may be dominated by radiators on the instrument which are less important to a listener who has a different spatial relationship to the sound. That’s true whether we’re playing a string, a wind, or a percussion instrument. (Paragraph) I do have a few suggestions for ongoing development of the tool. First, the tuner is biased toward the Western equal-tempered 12 tone scale. It would be great to be able to specify a model octave of a scale from other traditions, like South Asian or Middle Eastern, or from other historical Western tuning systems. The model octave could be specified with a simple table of frequencies with a few decimal points of resolution, and ideally I would be able to build a personal library of scale tunings. (Paragraph) The division of the semitones into eight buckets helps to reduce visual complexity, but a preference switch to increase that to ten would allow me to visualize the pitch deviations in units of ten cents. That might not be workable for the small screen of a phone, but there’s enough real estate on an iPad screen for that to be usable. (Paragraph) Similarly, a preference switch to activate the lines between the “correct” pitches for reference pitch production would help me work on microtonal pitch discrimination. (Paragraph) Previous review follows: Hey, IRCAM - you built something wonderful and useful! Please update it so it will run on iPadOS! **Developer response:** Hi Tburgueso, thank you for your good words about The Snail. The latest version of our app (2.3) should run fin on your iPad as well. UPDATE: Thanks you so much for your suggestions. Please reach out (easier!) at: https://discussion.forum.ircam.fr/c/the-snail or at thesnail@ircam.fr ### 5/5 — An exceptional tuning app *2022-08-26, version 2.3.3* This is a unique and excellent tuning app. I use it every time I need to tune any instrument. The display is particularly useful, as it allows you to view not only the fundamental frequency, but also the upper partials, allowing for particularly refined intonation. I'm absolutely thrilled that the app was recently updated so that it works once again with recent versions of iOS! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
