### 2/5 — Chords not detected

*2020-07-04, version 1.0.11*

Chords are not detect as you play. You have to touch the screen to reset every time. Not very efficient..I want my $$ back.

**Developer response:** Version 1.0.11 had this problem in some case.
Updating to 1.1.0 or above should solve the issue.

### 3/5 — Chord misdetections

*2020-05-10, version 1.0.10*

This app works well but some there are some fairly basic limitations:
- sus chords are detected as 9th’s. For instance, Dsus is displayed as Cadd9, even though the D is the bass..
- no support for 13th’s

If this was fixed this app would prove really useful!

**Developer response:** Hello, thank you very much.
Sorry, it took some time, but it's here, today in version 1.0.11  : the app now takes the lowest (bass) played note into account.
It still not perfect, I still notice some differences comparing to Logic Pro's chord detection, but very very few.
I really hope this new feature can make the app useful for you.
Also I introduced 13 and m13 chords too.
You're welcome to reach me at arfntz@gmail.com, so we can check chords together if you want.
Happy musiking,
Frantz.

### 3/5 — Nice, but can be improved

*2019-07-07, version 1.0.6*

A problem with this app is that it flashes constantly. If it were just to sustain the chord display until the next chord, or just fade to black in case of no input, it would be way easier to follow.
