Hi

Thanks for your fun app.

I've noticed that if you answer nothing at all with standard settings, the app shows 119 errors. Shouldn't it be an even number?

It's entirely possible I'm just misunderstanding how this works. But I have done multiple levels, over and over, and even slowed the effective wpm way down so that i'm pretty sure i'm not making any mistakes. (Although I am very new at this, tbf)

But the score stays stuck at 84%, 19 mistakes.

Sometimes pressing Try again crashes the app.

Hello,
the Koch Training works perfectly with my bluetooth keyboard on Android 10, but the Sounder does not work. There is no screen keyboard and no external keyboard available.

I will compliment you on the sounder idea, there's practicing and learning but hearing it in tones gives it a new feel, like a voice.

I have other characters on my keyboard that common Morse covers yet do not sound when entered, such as the period. Image given for convenience.

The app focuses on learning morse code through sound exclusively. Could it be possible to add a visual medium as well ?

Dear app developer:
Nowadays, our team has developed a tool that can detect and automatically repair accessibility problems in the app. We hope to receive your suggestions and opinions as an app developer.
Here, the accessibility problem I mentioned includes two types of problems: Text Contrast issue and Image Contrast issue. The former one corresponds to visible text, where there is a low contrast ratio between the text color and background color. The latter refers to images with a low contrast ratio between the foreground and background colors.
The following image shows the detection function and repair effect of our tool(this UI is from your app):
The figure on the left is the original page, the figure on the right is the repaired page, and the figure below is the problem detection report.

I want to know whether you think it is necessary to detect this problem and how effective you think our repair is. Sincerely hope to get your reply. Your reply is very important to me!
