## What is MorseLearnPro?

This is the Morse Codes learning App.
You are able to lean the Morse codes by steps.
There is a random generation function, you can practice listening of Morse Codes.
You can also freely select the volume, playback speed, and playback tone.

【additional function】
1) Reverb function
2) Noise function
3) Repeat function (Endless & Time specification)
4) Added a function to switch between hardware and software for keying waveforms.
5) Added accurate / fuzzy function as a keying method
6) Added adjustment function (10-step adjustment) for high-speed sound training.
7) Added omit function , - = and @ of Code Listen mode
8) Added buffer mode function of Code Study mode
9) A function that allows you to select the Morse code generation waveform from "sine waveform, triangular waveform, rectangular wave system, and sawtooth waveform"

The "reverb function" simulates the reverberation of the test site.
The "noise function" mutes the noise during actual communication.
"Fuzzy keying" is a function that reproduces a fluctuating signal like a vertical key that a person hits. Even if there is a little fluctuation, the reception difficulty will go up sharply.
Supported the QSB function.

## Key features

- Step-by-step Morse code learning
- Random generation for listening practice
- Adjustable volume, playback speed, and tone
- Reverb and noise simulation functions
- Multiple keying waveform options

### 5/5 — iOS16以降、音が出ないみたい

*2023-10-11*

iPhone7 Plus iOS15では使えていますが、 iPhone14 iOS16以降　音が出ません。 現在はiPhone14 iOS17.0.3ですが、このシリーズ全滅で音が出ません。→最新バージョンで正常動作しました。音が出ました。ありがとうございます。

**Developer response:** 互換性問題の報告ありがとうございます。
iOS15では使えているとの事ですので、iOSの互換性問題と思われます。
最新版Xcode15と手元にあるiPhone12 mini / iOS16.6.1で動作確認したVer2.2.0を審査に提出しました。通常1〜2日程度でリリースされると思いますので、再度ご確認頂けないでしょうか。
それでもダメとなると、H/W起因のため解決に時間を要する可能性が高いです。
※過去、iPhone本体左側のミュートスイッチをONされていたケースもありますので、念の為ご確認ください。
---確認＆報告ありがとうございます。無事動作しているとの事、安心しました。

### 1/5 — バグでしょうか…

*2021-10-19*

morselearn と　wabun morse の共にPRO版を利用しています。音で聴き始めると、文字が表示しません。バックもストップも出来なくなります。PRO版を辞めたいのでお金返してほしいです。よろしくお願いします。

**Developer response:** コメント恐れ入ります。
現状、所有している実機(iPhone8/iOS14.5/iOS15.2)、各シミュレータでは、正常に動作しておりますので、ご申告のような操作できなくなる動作不具合は確認できませんでした。
（ただし、iPhone mini/iOS15固有?で画面が乱れるようです。シミュレータ上で確認）
返金に関しては、アプリ開発者側からは処理できませんので、Appleに依頼してくださるようお願いします。（返金条件にはAppleの規定があります）
その後の調査で、iPhone13等/iOS15の場合に、ご指摘の現象が発生していること確認、対策検討中ですが、解決できておりません。申し訳ございません。

Ver1.2.0で、iOS15に対応しました。
