### 3/5 — Design wird besser. Sound beste.

*2026-01-25*

Hello mDecks. Why is the stop button just 3mm of size ??? Still. Need 3 attempts to hit. Every time!
Die Bedienbarkeit eine Katastrophe weil zu fummelig.
UI nicht intuitiv. Zb sieht man sehr schlecht warum ein bestimmter tab jetzt geöffnet ist und wie man ihn wieder zu kriegt. Da müsste der kontrast der bedienelemente dynamisch viel klarer mitgehen. So verfummelt man sich leider zu oft.
Loops setzen und einstarten dauert alles viel zu lange. Zum Üben brauche ich ein Werkzeug, kein Fummelquatsch. iReal Pro macht das vorbildlich, klingt leider nicht so gut.
Und hier das Lob:
Der generierte Sound ist erste Sahne und stellt alle anderen Playalong Apps in den Schatten.

### 1/5 — 没法用

*2026-01-20*

根本用不了，和声分析也不行

### 3/5 — Drives me bunker

*2026-01-04, version 10.8.3*

Drives me bunker, everytime I dont use this app for a while, I cant never remember how to close the bottom half that I dont want to see, its never intuitive, should be a no brainer…
Sounds great and all, but not very intuitive, the interface needs more work to be effortless.

### 4/5 — Mucho consumo de batería

*2025-09-16, version 10.8.3*

Sigue consumiendo batería aún estando en segundo plano

### 1/5 — Don’t bother

*2025-03-26, version 10.8.3*

This app is just awful.  Incomprehensible graphs and charts that are impossible to follow.  I’m sure someone put a lot of effort into this but it’s just counter intuitive and not worth the time to figure out.

### 4/5 — A great tool but needs refinement

*2025-02-21*

This app feels like it’s directed at the jazz keyboardist and pianist.  Somehow, I feel like the user interface could be made to be more intuitive.  Navigation through the app is a bit complex. However, I like all the features that the app provides. I think more work needs to be done on the guitar fret board. The guitar resizing needs some work and needs more voicings for guitar.  Overall it’s been a helpful tool for understanding harmony and composition.  Thanks!!

### 1/5 — Extremely Buggy

*2024-12-05*

Extremely buggy. It’s impossible to edit songs within the app. Try changing chords and then hit “back” and nothing saves. When trying to alter the title or other properties and hitting save it saves it briefly and then reverts back or renames it to “Untitled.” On top of all that there are so many missing features and missing customizations. Want to turn off the lead-in bar of clicks? You’re out of luck. Want to add a melody line? Again, out of luck. Want to add ukulele chords or custom tunings? Once again, out of luck. For an app (and IAPs) that are so expensive, this really is a disappointing purchase.

### 5/5 — Best app ever!

*2024-11-29, version 10.3.1*

Amazing app!!!

### 2/5 — Crashes again

*2024-10-19*

Crashes when touching a chord on the map or the staff and when tapping play button.  Works fine when touching the menus on the right side or else where.  I’m running version 10 on iPad os 18

### 1/5 — Insatisfecho

*2024-10-15, version 10.2.1*

Tiene mucho que mejorar: todas las funciones se compran aparte, incluyendo las canciones. Los standards no están del todo bien, algunos vienen con compases de más, y si se requiere cambiar o quitar algún acorde no se puede, tampoco se pueden editar las canciones ni añadir o eliminar compases. En caso de que requieras crear una composición nueva si no compraste los acordes no podrás ingresar ningún acorde, la página se queda en blanco. No se puede exportar el audio a mp3.
