Key takeaways for Koch Trainer
Where is it heading?
The amateur radio utility market is shifting toward apps that offer consistent performance and progress tracking, leaving Koch Trainer exposed due to its lack of maintenance. Without a fix for the current stability regressions, the app will continue to lose its remaining user base to more reliable alternatives.
- Frequent crashes on current iOS versions prevent training session completion, which directly causes the negative sentiment trend.
- The lack of updates since 2014 leaves the app vulnerable to platform-level regressions that the developer is not addressing.
The SWOT
- Specialized pedagogical approach establishes authority in the amateur radio training category
- Session grading and accuracy tracking would address top user requests
Next best moves
Rebuild launch and session-change logic because current instability renders the app unusable → restore baseline functionality

The app's primary value is its pedagogical rigidity…
Read the full takeSince the last report: Severe stability regressions following the latest update have rendered the app unusable, causing a shift from a stable training utility to a declining product with negative user sentiment.
Bottom line
Restoring basic stability is the prerequisite for any further development, as the current crash rate prevents users from accessing the core training value. Addressing these regressions would stabilize the user base before the team considers adding requested progress-tracking features.
