### 5/5 — Chouette

*2026-07-05, version 1.0.0*

Sympathique petite app. L’icône dans la barre des menus est trop petite et l’icône de l’appli ressemble un peu à de l’ “AI slop”, on aimerais voir un logo dessiné à la main par un humain avec plus de charme. Mais ça fonctionne bien :) Pourriez-vous rajouter une fonction pour les gens qui jouent en la ( A ) 442 ou 432hz ou autre et pas seulement pour 440hz comme actuellement ? Merci beaucoup !

### 2/5 — 440? 442? 444?

*2024-01-11, version 1.0.0*

Impossible de savoir ni de choisir.

### 3/5 — Good, but still a work-in-progress

*2023-12-24*

The app isn't averaging data properly. You play a note on the guitar such as the low E string (E2) and it swings wildly between saying the pitch is Eb2 ("take higher") and E2 but very sharp ("take lower".) The pitch in Hz displayed shows that the fluctuations aren't nearly as wild as the text display indicates.

### 1/5 — Can't use own mic

*2023-05-17*

I'm using this on an M2 Mac mini, with a USB audio device attached. There's no way to set the mic to my audio device, even though it's set as the system default, and there's no "settings" dialogue to fix it.
Might be ok if your device has a built in mic, otherwise it doesn't hear anything. 
Will look for a more sophisticated app.
