### 5/5 — Super accordeur précis

*2026-07-16*

Il est très pointilleux, mais du coup ça permet de corriger avec précision les petites erreurs d’accordage que les autres applications pourraient permettre.

### 4/5 — Ads are too hard to click out of

*2026-07-11*

I understand the point of ads for a fee app. I just wish they were easier to click out of. The x in the corner is often hidden under other stuff

Too many “you’ve been hacked”banners so not using.
