Disappointed. ### 3/5 — iOS18対応アプデ求む！ *2024-10-15, version 2.0.0* 18にアップデート後に起動すると常時ノイズがしてチューニング出来ません。いつでも何処でもポリチュしたいので早急に対応お願いします♪ ### 2/5 — iOS 18 update please *2024-09-18, version 2.0.0* Since updating to iOS 18 it doesn’t function properly anymore. Every sound is being picked up by the microphone and sends right back through the speakers resulting in a scratching sound like FaceTiming with someone sitting next to you. Switching to the Peterson app for now until this hopefully gets resolved. ### 3/5 — Não afina *2024-07-31* Depois que passei pro iPhone 15pro , o aplicativo não está afinando , mesmo usando o adaptador original comprado na Apple Store ! E todos os outros app de música que uso estão funcionando perfeitamente, até mesmo um outro afinador de outra marca , strobosoft . No caso do Polytune , ele está saindo o áudio no fone , coisa que não acontecia antes , mas não modula o afinador !! ### 3/5 — Abandonware-ish *2022-05-29, version 2.0.0* Do not download. It hasn’t been updated or worked on a current iOS for quite some time. 2022 UPDATE: Still hasn’t been updated but PolyTune again works. Currently okay on iOS 15.5 ### 3/5 — Very cool but... *2022-05-01, version 2.0.0* I’d love to see AUv3 support to be able to use Polytune inside AUM in live use without having to switch apps. ### 4/5 — App freezes *2022-02-04, version 2.0.0* Really good tuner, but it has started freezing when awakening from auto-lock on iPhone. Only fix is to quit and restart app. Needs a fix. ### 3/5 — 아이패드 프로 에러 *2021-10-27, version 2.0.0* 휴대폰은 잘 되는데 프로는 에로로 작동이 안되네요 ### 2/5 — Lots of bugs / update needed *2021-06-03, version 2.0.0* When it works it's very acurate but it didn 't have an update in 4 years and it's very buggy with IOS14.5. It will freeze at any moment or stop recognizing notes. It s a 5€ app, it should have a well deserved update! ### 3/5 — 対応をお願いします *2021-04-09, version 2.0.0* アップデートが長らく行われておらず使用出来ません。可能であれば新しいOSにご対応をお願いいたします。 ### 4/5 — Please add buzz feiten tuning mode. *2021-03-31, version 2.0.0* Overall I’m really happy with the app but because I use the buzz feiten tuning system I have to tune all the strings to E. The Korg tuner has the BF system integrated so you can tune the open strings and make a chord. I would also like to be able to incorporate custom tunings of my choosing. Also when i play a note I want, I would like to be able to set it as the default for that string even if it is not the exact standard frequency. For example, perhaps i want my A to be 443.2Hz instead if 440Hz. That does NOT mean I want all the other strings to move by the same percentage though. I want to pick each string. I would like this capability with the pedal tuner as well. First add BF tuning mode!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Bad Contrast 、表示が暗いです *2025-08-27, version 2.0.0* 暗くて見にくいiPhoneの照度を最大にしてちょうど良いくらいなのでもう少しコントラスト出るように明るくしてほしいです。 8年間メンテナンスされてないアプリだから無駄かもしれない。 買収後ダメになった会社 ### 1/5 — 아이폰14프로맥스에서 피드백 하울링 뜨면서 사용불가 *2025-08-15, version 2.0.0* 업댓 해주실거죠? 유료앱인데, 오늘 앱만 열어도 피드백이 생겨서 사용을 못하고 있네요 아놔 진짜 ### 1/5 — ゴミ *2024-07-18, version 2.0.0* 1弦開放のEが反応しない。 使い物にならなかった。 ### 1/5 — 인식이 안돼, 그지같네 *2021-05-06, version 2.0.0* 인식이 잘 안돼요. 뭐여 이게 2017 년이 마지막 업데이트인게 말이 됨? 그리고 432 hz 까진 지원해줘야지 435 hz 는 너무 애매해. 뭐야 이게 회사가 망한 것도 아닌데. 돈주고 샀지만 삭제. ### 1/5 — Increíble *2021-04-28, version 2.0.0* Increíble que hayan actualizado la app sin corregir el único error de la que es el bloqueo automático de pantalla. ### 1/5 — Ne fonctionne pas *2021-03-05, version 2.0.0* L’application n’entend que sa les notes de ma guitare et est donc inutilisable... ### 1/5 — PolyTune *2021-03-02, version 2.0.0* Needs updating, when launching, the app crashes. ### 1/5 — App lädt nicht mehr *2021-02-24, version 2.0.0* Absturz beim Start ### 1/5 — Not like the PolyTune. *2021-02-23, version 2.0.0* Screen doesn’t stay lit and doesn’t register for crap. I recommend the pedal but not the app. Waste of 5 dollars. ### 1/5 — No Longer Works *2021-02-20, version 2.0.0* App crashes on launch and is no longer usable. Do not buy. ## Most praised reviews (10 highest-rated) ### 5/5 — It’s The Nuts *2025-08-14, version 2.0.0* I’ve had this tuner app since it came out. It’s fantastic. I never leave home without it. ### 5/5 — 🩵 *2025-07-15, version 2.0.0* It actually works really well. What a bargain. ### 5/5 — Please Update and add features! *2025-06-10, version 2.0.0* I recently bought this app as Inlove polytune. but please if you could give an update like more options on pitch Hz low to 420hz up to 455hz and more instrument to tune not only guitar and bass. Thanks in Advance! ### 5/5 — Ottima *2024-12-10, version 2.0.0* Peccato che non venga più aggiornata da anni. ### 5/5 — Stuck *2022-05-03, version 2.0.0* When I go to the background and go back to Polytune, it gets stuck. Please fix it. ### 5/5 — Just like my pedal! *2021-09-05, version 2.0.0* I love my PolyTune app! It’s like my PolyTune Noir but I can use it with my acoustic when I don’t have the pedalboard with me. I have it set to strobe for super accurate tuning and it doesn’t disappoint. I have no idea how people are getting negative reviews going. When I tune, I set it on top of the acoustic so it’ll pick it up better. Try that out if it’s having trouble hearing you. Mine also sees individual notes I’m tuning if I tune with a capo. I can’t do the all 6 at the sane time thing that way, but that’s only used as a spot-check after I’ve tuned. That means it’s basically still a regular tuner when you use alternate tunings. Not a big deal. If it still gives grief with capos or alternate tunings, maybe try setting it to the chromatic tuner setting? I’ve never had issues, but they built that into the settings for some reason or another. ### 5/5 — Excelent *2021-08-13, version 2.0.0* Great tuner, works perfectly. I hope that you will add a widget ### 5/5 — 5 stars *2021-04-30, version 2.0.0* The only tuner app and Hardware I use is TC POLYTUNE , and I can’t live without this now ### 5/5 — 2021/4/27更新。素敵なアプリだからこそ *2021-04-27, version 2.0.0* 今のiOS13に最適化できるようアップデートをお願いします🙏機能はとても良いです。 更新ありがとうございます😊UIが正しく表示されて見やすくなりました感謝します。 ### 5/5 — Cannot launch on iOS 14.2 *2020-12-10, version 2.0.0* PolyTune cannot launch on iOS 14.2 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
