Morse Master 3.5.3: - Japanese Wabun in the text translator now accepts hiragana and converts it to katakana. Wabun has no kanji, so you'll see a note when kanji are skipped. - The reminder card on HQ now appears at most three times, and you can close it any time with ×.

Morse Master 3.5.2: - The first onboarding screen is now a demo: SOS plays on its own and the letters surface with the sound. No quiz, and you can skip it at any time. - Redesigned subscription screen with your learning-path curve and rank progress, so pricing and benefits read at a glance. - Training reminders now adapt to your streak and reviews due. Enable them in Settings. Finishing Koch or Daily Sprint clears today's reminder, including training synced from Apple Watch or iCloud. - Fixed reminder timing after changing time zones.

Morse Master 3.5.1: - Training reminders now adapt to your streak and reviews due. Enable them in Settings. - Finishing Koch or Daily Sprint clears today’s reminder, including training synced from Apple Watch or iCloud. - Fixed reminder timing after changing time zones and improved the first-launch experience.

Morse Master 3.5.0: - New Apple Watch app: streak, reviews due, characters unlocked and today's Daily Sprint at a glance. - Callsign, QSO and contest drills now keep a personal best — your top accuracy and the speed you reached it at. - Listening practice now records the speed you listened at, and a listening round no longer resets your sending speed. - Fixed a training round counted twice after you left and resumed it, and fixed the launch screen stretching on some devices. - Anonymous usage statistics show us where learners get stuck. Turn them off any time in Settings → Privacy.

Morse Master 3.4.1: - Fixed rare cases where Morse playback could skip tones, cut off the final tone, or stay silent for very short characters. - Improved playback completion, interruptions, and output-device changes. iCloud sync is now available on macOS 14+ for training progress, settings, and history.

Morse Master 3.4.0: - PRO members can enable iCloud Sync from Profile to keep training progress in sync across supported Apple devices. - Passing the listening drill now unlocks the next Koch stage; sending and confusion drills remain optional practice for the current stage. - Active sessions now confirm before you leave, with improved localized dates, Traditional Chinese wording, and reliability.

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.

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.

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. - Better stereo-channel recovery and consistent 5–50 WPM estimates. - Safer backup validation and more reliable audio-history cleanup. - General stability and localization improvements.

Morse Master 3.2.0 brings a major Audio Decode upgrade: - A substantially improved adaptive decoding algorithm handles variable-speed keying, Farnsworth spacing, fading, background noise, and uneven recordings more reliably. - 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.

Morse Master 3.1.8: This update: - Adds PRO Audio File Decode for importing short local audio files. - Improves keyboard decode settings sync and shared preference handling. - Tightens Morse input feedback, audio interruption handling, and replay cleanup. - Improves Daily Sprint, SR summaries, celebrations, and release validation.

Morse Master 3.1.7: This update: - Makes the paywall follow live App Store offer data and StoreKit eligibility. - Shows trial or intro-offer wording only when the current user is eligible. - Keeps normal subscription wording when no eligible offer is available. - Clarifies renewal, cancellation, and PRO benefit wording.

Morse Master 3.1.6: This update: - Expands the free Koch path to the first 18 stages, covering letters and digits. - Adds PRO operator packs for QSO, Q-code, callsign, contest, and CW abbreviations. - Makes live decoding unlimited with PRO while keeping a daily free trial. - Adds branded milestone sharing with an App Store QR code. - Cleans up key feedback so dit/dah input stays separate from the real side tone.

Morse Master 3.1.5: This update: - Makes the Koch training access boundary clearer and expands the free learning path. - Adds richer milestone sharing for training progress and achievements. - Improves accessibility, readable sizing behavior, iPad layouts, keyboard navigation, and reduced-motion handling.

Morse Master 3.1.4: This maintenance update: - Improves the small-screen sending layout and shared tap behavior for disabled controls. - Clarifies restore-purchase and partial backup-import feedback. - Makes legacy training migration counts and audio playback switching more reliable.

Morse Master 3.1.3: This maintenance update: - Keeps the compact Morse converter keyboard and legacy audio history deletion behavior from the 3.1 line. - Clarifies legacy audio handling: deleting old history entries only hides them, while migration may clean an old source after saving a relocation map. - Tightens release validation so App Store metadata and landing-page version fallback are checked against the app version.

Hotfix: - Fixed a Koch training progression issue where returning after a break could leave completed stages stuck on optional practice instead of continuing the normal lesson path. - Aligned HQ, Daily Sprint, and direct training entry points so they advance to the correct next stage and apply access rules consistently. - Added broader regression coverage for stage boundaries, subscription state, Daily Sprint state, and lesson status combinations.
