Features & Capabilities

Koch Trainer is a morse code trainer that uses the Koch Method developed by the German psychologist Ludwig Koch in the 1930's. The method basically states that you should learn morse code at the speed you expect to receive, by training your reflexes to respond to code sent at 20 WPM you'll learn the code much faster.

User Reviews

Koch Trainer is a serious CW training tool that uses the Koch method and offers strong customization (WPM, spacing, pitch, test type) and cross-device support at a modest price. It’s praised as one of the few non-toy apps that truly teaches Morse, with features like a scratch pad. However, multiple reviews report stability issues (crashes, startup failures) across iOS versions and devices, frequent audio problems (no tones or speaker limitations, headphone requirement, pops), a dated or non‑intuitive UI, and a lack of built-in feedback or scoring to track progress. Powerful but unreliable for some users.

Pros

Serious CW training tool that uses the Koch method and is praised as one of the best ways to learn Morse.
Rich customization: adjustable WPM, spacing, pitch, test length, and supports Koch and Farnsworth; practice modes include letters, words, QSO.
Scratch pad feature is helpful for practice.
Cross-device compatibility across Apple devices (iPhone/iPad/Mac).
Affordable, complete package with no add-ons.

Cons

Frequent stability issues: crashes, startup failures, and freezes across iOS versions/devices.
Audio problems: tones not audible on some devices; speaker issues; headphone requirement and audio pops.
Non-intuitive UI and lack of user guidance.
No built-in progress tracking or automatic feedback to show mistakes.

Recent reviews

Every other CW App is a toy by comparison. However, it has bugs, namely a transient miss sending (at the outset) when using an iPhone.

With iOS 18.3, this app is unstable and crashes. It hangs when changing WPM. Will not play on iPhone speaker, regardless of mute/volume settings. Headphones required. I’d like my money back.
