## Most critical reviews (7 lowest-rated)

### 1/5 — Stürzt immer ab

*2024-12-04*

Stürzt immer ab nutzlos

### 1/5 — HarpNinja Diatonic

*2020-03-07*

This is a useless app a total waste of money! Basically it does nothing.

### 2/5 — Confusing to use

*2019-01-27, version 1.3*

I’m a idiot when it comes to music and I had no idea how to use this app. I thought it would be simple and tell me what I was playing.

### 3/5 — Setting need to save

*2021-01-13, version 1.3*

If you switch away fry the app but it’s still open in the background when you switch back it reverts to C harmonica. Should stay on what you had set A for example but it doesn’t. Makes it frustrating because you have to select harp key again.

### 3/5 — Potential but flawed

*2019-06-01, version 1.3*

I got this based on David Barrett’s recommendation. It has functionality but needs work.

Here’s two major flaws:

The controls are a problem. Changing the key is poorly designed with the controls in such small shapes and located too closely. 

There’s no support for low tuned harmonicas.

### 5/5 — Expensive

*2015-11-05, version 1.2*

Great tool for learning harmonica but wish it was cheaper...

### 5/5 — HarpNinja - Really useful tool

*2015-05-28*

I am just learning to play the harp.  This program really helps me to sharpen up my single notes.  Have tried bending without much success but the program is very accurate in telling you how far off the bend you are (;-))
