## What is Morse Code?

Morse Master helps you learn Morse code by ear with a structured Koch-method path and practical CW drills. Instead of memorizing dots and dashes from a chart, you train the sound patterns used in real copying and sending.

Training:
- Progressive Koch lessons that introduce characters step by step
- Daily Sprint sessions for focused 3–5 minute practice
- Listening and receive drills for Morse copy
- Sending practice for rhythm, timing, and keying control
- Weak-character review and confusing-pair drills
- Adjustable WPM, Farnsworth spacing, pitch, noise, and fading
- WPM Ladder, Free Range, and copy practice for extra reps

Signal tools:
- Text to Morse and Morse to text conversion
- On-device audio decoding from recordings or microphone input
- Flashlight Morse transmitter
- Training history, progress, badges, and weak-character review

Morse Master works offline and does not require an account. It is built for beginners, ham radio learners, and CW operators who want a clear daily path from first sounds to steadier copy and sending.

### 5/5 — Morse is good!

*2026-06-23*

Application - very good, but i can’t buy it in Russia. Thanks USA for this…

**Developer response:** Thank you for the thoughtful note. I'm sorry the purchase flow is not available for you in Russia. App Store purchases are handled by Apple's billing and regional availability, so we cannot fix that directly inside the app, but we appreciate you using Morse Master and will keep the free learning tools as useful as possible.

### 1/5 — Doesn’t work whatsoever. Total scam

*2026-06-16*

Doesn’t work whatsoever. Total scam

**Developer response:** Sorry you had such a bad experience. Morse Master is an offline Morse learning app with no account requirement and no ads, and the free tools should remain usable without purchase. If something failed for you, please contact us through the support page with your device, iOS version, app version, and the feature that did not work so we can investigate.

### 5/5 — Omggg!!!

*2026-02-06*

I learned the morze abc in 40 minutes and i tested it on a translator and yes i can make sentenses now, this app is insane🔥

**Developer response:** That’s amazing progress. Thanks for sharing it! Morse Master is built to make the first steps feel clear and fast, then help you keep improving with listening, sending, and daily practice. We’ll keep it focused and ad-free.

### 1/5 — Can’t decode from audio

*2025-11-16*

If you’re looking for an app to help you decode from audio, this ain’t it.

**Developer response:** Thank you for the honest feedback. Audio decoding is very sensitive to signal quality, speed, spacing, background noise, and microphone input, and older versions did not handle some recordings well.

The latest version includes an updated local audio decoding flow and clearer training tools for listening, sending, and reviewing weak characters. If you are willing to try again, please update to the latest version and test with a clean Morse tone recording.

We’ll keep improving audio decoding reliability in future updates.

### 5/5 — Great App

*2025-08-15*

The best App

**Developer response:** Thank you! We’ll keep improving Morse Master as a focused Morse learning and training app, with no ads and no unnecessary clutter.

### 1/5 — Incomprehensible

*2025-01-14*

Don’t waste your time or money.   The software may be brilliant, but I never got it to work. Instructions, such as they are, were nearly impossible to find.

**Developer response:** Sorry for the frustrating first experience. The current app has a clearer training path, onboarding, signal tools, and no ads, but we can still do better at making instructions easier to find. Thanks for calling that out.

### 1/5 — Scammy ads

*2025-01-11*

I tried to use this but it has very scammy adds saying your iPhone has a virus. Beware

**Developer response:** We’re sorry you saw that. The current version of Morse Master has no ads and should never show virus-warning popups. Please update to the latest version; if you ever see anything like that again, contact us with a screenshot so we can investigate immediately.

### 1/5 — Something is off

*2025-01-01*

Why is the Morse code translator only converting into Latin? This makes no sense. I'm going to give it one star and update until I get a response…

**Developer response:** Thanks for raising this. Morse code itself is defined for specific characters, so the translator focuses on International Morse Code characters, including Latin letters, numbers, punctuation, and supported extended letters. We’ll keep making that limitation clearer in the app.

### 1/5 — Nah

*2024-10-30*

Did not decode the Morse code I fed it.

Also, can only translate Morse to Latin, and while I appreciate the irony of converting one dead language into another it’s still not terrible useful.

### 5/5 — Aprendizaje

*2024-10-22*

Puedes aprender el código morse para por si acaso mandar señales en código morse

## Version history (last 5 releases)

### 3.3.0 — 2026-08-11

Morse Master 3.3.0 fixes how your training results are recorded:
- Sending and copy results used to be recorded as listening scores, which put the wrong characters on your review schedule. This version records them separately by source, so each skill is scored on its own.
- Your review progress is kept as it is: Koch stage, streak, rank, review intervals and full training history all carry over — nothing starts again. Over the first few days each character comes up for one review so the schedule can realign with how you actually hear it.
- Copy practice now uses aligned comparison: one missed character no longer marks the rest of the line wrong.
- Manual corrections in audio decoding no longer count as listening errors — you are correcting the decoder's output, not your own hearing.
- Added real-word copy practice; weak-character detection now uses recent performance.

### 3.2.2 — 2026-07-29

Morse Master 3.2.2 improves audio reliability and data safety:
- Recordings can now run for up to five minutes, and Morse playback stops before recording begins.
- Imported audio is normalized to mono 8 kHz before decoding, with support for source files up to 128 MB.
- Better stereo-channel recovery and consistent 5–50 WPM estimates.
- Safer backup validation and more reliable audio-history cleanup.
- General stability and localization improvements.

### 3.2.1 — 2026-07-23

Morse Master 3.2.1 improves audio reliability and data safety:
- Recordings can now run for up to five minutes, and Morse playback stops before recording begins.
- Imported audio is normalized to mono 8 kHz before decoding, with support for source files up to 128 MB.

### 3.2.0 — 2026-07-17

Morse Master 3.2.0 brings a major Audio Decode upgrade:

- Confidence-aware alternatives make ambiguous signals clearer instead of presenting every decode as certain.
- New Koch characters are introduced before blind listening begins.
- Training keys now enter exactly one dot or dash per press, while continuous input remains available in the Morse keyboard.
- Improves purchase handoff and overall reliability.

### 3.1.8 — 2026-07-05

Morse Master 3.1.8:
This update:
- Adds PRO Audio File Decode for importing short local audio files.
