### 2/5 — Приложение не работало

*2026-03-11, version 1.4*

Оплатила до версии pro и приложение не работает

### 3/5 — Good

*2024-02-27, version 1.4*

Can you add like not only see you like can you go back to the highest not like EBA?

### 3/5 — Not working on Apple Watch Ultra

*2023-12-31, version 1.4*

I downloaded it primarily for Watch usage. It can’t detect the audio even if the permissions are ok.

### 3/5 — перестал работать((

*2023-05-24, version 1.4*

все было супер, но почему то перестало работать

### 4/5 — It tunes well

*2022-11-21, version 1.4*

It tunes trumpets well but everything else alright

### 2/5 — Inaccurate

*2022-11-05, version 1.4*

Not good for double bass it always 25 cents sharp or flat.

### 2/5 — Watch app doesn’t work

*2022-10-26, version 1.4*

I wanted a tuner on the Apple Watch and was initially happy to find Tune. The iPhone version works well but the watch version says “Listening…” and then “Phone not reachable”. Then it closes. I’m not sure what is wrong. My phone is right next to it. It would be nice to have more information.

### 4/5 — Good app

*2022-07-07, version 1.4*

Awesome cool helpful only 4 star because the app has only 1 octave and to reach the second you need money.

### 4/5 — So far so good

*2021-06-28, version 1.4*

It’s a great app with a cool looking UI. So far I haven’t seen any adds, but on apps like these it’s bound to happen. I hope not though as adds really clutter up the screen and take away from the minimalistic look of this app. Other than that, tuner is pretty good and has all the functionality you need as a beginner to advanced musician. I wouldn’t recommend this tuner to soloists but for everyone else it’s great.

### 2/5 — Langsam

*2020-11-06*

Reagiert zu langsam

### 2/5 — Not a real Watch app

*2020-09-27, version 1.3*

I wanted a tuner app for my Apple Watch, and this was the top of the list. I downloaded it, but it only works if you have the iPhone running the app at the same time. 

It’s probably a fine phone app, but that’s not what I’m after this time.

### 4/5 — Not Working on Watch 5

*2020-08-20, version 1.3*

Not working on Apple Watch 5

### 1/5 — Paid version doesn’t work

*2025-11-06, version 1.4*

It doesn’t work - paid for it and got none of the extras promised. No transposition. No additional colour. Doesn’t even tune - a scale flashes for a brief second and disappears or the app hangs.

App support doesn’t work. Just takes you to promote their other app Fretello. No way to contact the developer.

### 1/5 — Nicht für Geige geeignet.

*2022-10-31*

Die Konzeptidee finde ich gut, allerdings kann ich die Eignung für die Geige nicht erkennen. Die korrekt gestimmte G-Saite wir hartnäckig als korrekte D-Saite ausgewiesen…

### 1/5 — Apple Watch App mit iPhone Mikro ist Quatsch

*2022-10-08*

Apple Watch App mit iPhone Mikro ist Quatsch. Ansonsten ist die App auf dem iPhone ganz brauchbar.

### 1/5 — Apple Watchで表示されない。

*2021-08-23, version 1.4*

Apple Watchで表示されないのは、とても残念でした。課金した上でピッチを変えられる数少ないアプリなのに、Apple Watchで使うことが目的だったので残念ながら使いません。

### 1/5 — This is crap

*2021-07-30, version 1.4*

I doesn’t know what a c is an changes to e flat or d

### 1/5 — Cannot upgrade even after paying?

*2020-09-27, version 1.3*

Does not let u upgrade to pro even after paying???
What crap is this, needs to be removed from the App Store.

### 1/5 — Schade...

*2020-01-24*

... um das Geld. Leider springt während des Stimmens meiner Geige der Ton ständig auf einen anderen, falschen Ton. Hätte ich diese App vorher ausprobieren können, dann hätte ich sie auf keinen Fall gekauft. Schön eingefädelt vom Anbieter!

### 1/5 — Doesn’t work

*2019-11-11, version 1.3*

The old version did it beter

### 1/5 — SO BAD

*2019-10-03, version 1.3*

I hate this app SO much!!!! It just sits there doing NOTHING!!!! Do not download!!! 😡😡😡😡😡😡

### 1/5 — Mikrofonzugriff nicht möglich

*2019-09-05*

Beim der Einrichtung leitet die App in die Systemeinstellungen weiter um den Zugriff auf das Mikrofon zu erlauben. Allerdings ist die Applikation dort nicht gelistet.

### 5/5 — Everything I needed

*2026-02-21, version 1.4*

It does exactly what I need from it. Plays the note I’m trying to tune to or I play the note and it tells me how out of tune I am. This app is simple, which is perfect because that all I need/want it to be.

### 5/5 — 十分良いと思う

*2025-05-06, version 1.4*

シンプルだし使いやすいよ

### 5/5 — Прекрасный тюнер

*2023-03-29, version 1.4*

Очень удобно что он хроматический, и нет ограничений по струнам, как в других приложениях, так как играя любую ноту, он сам определяет ее. Есть очень полезная функция, когда можно эту ноту воспроизвести и подбирать ее на слух. 
Спасибо за такое простое и удобное приложение

### 5/5 — Perfect

*2023-03-03, version 1.4*

This app is a perfect free easy tuner. I tune Saxophone with it

### 5/5 — The minimal user interface is definitely worth it by itself.

*2023-01-18, version 1.4*

It’s functions whilst looking absolutely splendid!

### 5/5 — Klasse Tuner

*2021-12-19*

Stabil und visuell cool und klar umgesetzt. Bin sehr happy mit der App.

### 5/5 — Gut

*2021-03-14*

Kleine, einfache und leicht zu bedienende App zum Stimmen deiner Gitarre. Was brauchst du mehr?

### 5/5 — Stimmgabel immer dabei

*2021-01-06*

Ich bin begeistert von der App -obwohl ich vermutlich nur einen Bruchteil ihre Funktionen nutze. Ich benutze sie nur als Stimmgabel, also um immer das richtige "a" zu haben. Jedenfalls dafür ist die perfekt, denn eine Stimmgabel habe ich selten in der Tasche als mein Handy.

### 5/5 — Muito bom

*2020-07-08, version 1.3*

Adorei a afinação, prático e simples. Melhor do que muitos que estão no mercado

### 5/5 — Amazing App

*2019-01-03, version 1.1*

I am very well impressed about the quality if this amazing app. It is incredible accurate and it manages the sound frequencies till it be the right pitch. I am surprised it be free for such an outstanding app!
