All existing ear-training features remain available.

This v1.2 update focuses on faster training starts and a more comfortable, reliable playback experience. - Faster training starts - Playback now begins as soon as the first training loop is ready, while the remaining audio is prepared progressively in the background. - Scrolling and controls stay responsive while additional loops are being prepared. - Flexible spoken guidance - Choose `Brief`, `Detailed`, or `Off` for spoken explanations in Sound settings. - Detailed explanations are given enough complete four-beat bars so the ending is not cut off. - Improved background playback controls - Play and pause are more reliable from Control Center, the Lock Screen, and Dynamic Island. - Training that you paused stays paused after audio from another app ends. - Continue Training - Restart recently played training directly from the Home screen. - The in-app Stop button now ends the training completely and clears both the playback panel and system playback information. - Better controls and accessibility - Bottom scrolling space is now consistent across training screens so the playback panel does not cover the last item. - VoiceOver announces metronome, piano, and guidance volume by name and adjusts each in 5% steps. - Tempo step buttons and playback panel transitions have been refined.

This v1.1 update focuses on training playback, VoiceOver accessibility, and clearer multilingual spoken guidance. - Improved VoiceOver playback flow - Starting playback from a level row now moves focus to the playback panel more reliably. - VoiceOver users can still move to other level rows during playback to review course content. - Clearer spoken guidance - Progression guides now distinguish minor scale degrees more clearly, such as `minor one`, `minor two`, and `minor four`. - English interval names now use natural words such as `second` and `third` instead of relying on abbreviated ordinal text like `2nd` or `3rd`. - Refined training playback stability - Start and stop flow was rechecked across interval, chord, scale, and progression training. - The existing mixed loop playback path was refined so piano, metronome, and spoken guidance stay more consistent inside a fixed BPM.

This v1.0.2 update focuses on making training playback more stable and dependable. - Improved background playback stability - Reworked the training playback path to reduce cases where loops break or only part of the audio keeps playing in the background. - Training audio is now driven by prebuilt mixed loop files for more reliable continuous playback. - Smoother preparation and restart flow - Replaying the same course with the same tempo and sound balance now fits a faster preparation path. - Starting a new course more cleanly clears the previous playback session, reducing long silent gaps. - Refined audio adjustment flow - Tempo and sound adjustment flows were refined so checking sample sound and starting actual training feels more natural.

- Improved background playback stability - Added new metronome sounds
