This release fixes inconsistent Chinese characters across lessons. What's New • Changing the Simplified or Traditional Chinese preference now updates an already-open lesson immediately. • Chinese lesson search and answer checking now work across both scripts, allowing learners to search or respond using either Simplified or Traditional characters. Improvements • The selected Chinese script is now presented consistently in lesson lists and suggestions, guided lesson content, every quiz type, tutor-chat previews, completion and review dialogs, learning summaries, notifications, reminders, copying, sharing, and newly created flashcards. • Lesson search, reuse, and opening now apply stronger mother-language and Mandarin/Cantonese compatibility checks. Bug Fixes • Fixed learners with Simplified Chinese selected seeing Traditional Chinese lesson cards and lesson content from the shared catalog. • Fixed unrelated public catalog lessons and legacy cached rows appearing in a learner's lesson library. • Fixed lesson suggestions and notification links being able to associate or open lessons created for a different mother language or Chinese dialect. • Fixed script changes affecting visible answer comparison while preserving user-entered text exactly as typed.

This release adds a notification center and study reminders, lets learners open a contextual tutor chat directly from a translation, expands sign-in choices, improves RADLing on tablets and desktops, and makes shared lesson, dictionary, and pronunciation content more reliable. What's New • Notifications are now used to alert users when message responses are made or when lessons have finished generating. • Study reminders can now be scheduled for selected days and a preferred local time, with controls for notification permissions and delivery preferences. • Translation includes a new Dive In action that opens a tutor conversation with the translation as hidden context. A dismissible context preview makes it clear what the tutor is using while leaving the composer ready for a natural follow-up. • RADLing can now offer phone-code sign-in and server-enabled Google, Apple, Facebook, Microsoft, and WeChat sign-in options, where supported, in addition to the existing email flows. • Layouts now adapt more naturally to tablets, desktops, and wide browser windows, with constrained reading widths and navigation designed for larger screens. Improvements • Dialog characters do a better job keeping consistent voices across lesson generation, guided lesson playback, quizzes, refreshes, and app restarts. Audio reuse now matches the exact speaker, model, language, text, and speed. • Missing lesson and dictionary audio is resolved through background work and attached to its exact lesson or dictionary source, allowing generated public audio to be reused safely. • Lesson generation is more resilient to temporary database and AI-service failures, with durable task leasing, bounded concurrency, retries, backoff, and recovery after worker restarts. • Lesson and chat completion updates can arrive even after leaving the screen or closing the app. • AI models have been upgraded to improve overall performance for responses and lesson generation. • Pronunciation pregeneration is more reliable, ensuring faster playback for users. Bug Fixes • Fixed dialog speakers changing voices between the lesson plan and quiz or after lesson data was reloaded. • Fixed missing dialog and vocabulary audio failing to persist issues. • Fixed server side issues that could leave lesson generation stalled. • Fixed various other performance and reliability bugs.

This update improves audio responsiveness, cleans up generated pronunciation audio, makes Chinese lessons more consistent, and fixes several lesson, vocabulary, and dictionary edge cases. What's New • Chinese lessons now have stronger handling for Mandarin and Cantonese script consistency. Improvements • Voice recording controls are more responsive, especially when starting a new recording from chat. • Chinese learning content should no longer mix Simplified and Traditional Chinese in the same lesson when a specific script is expected. • Lesson lists and learning progress handle generated or in-progress lessons more consistently. • Chinese localization now uses a more accurate translation for 'flashcards'. Bug Fixes • Fixed generated pronunciation audio that could include an unintended extra word or otherwise not match the displayed text. • Fixed deleted vocabulary and dictionary words appearing in places where they should no longer be selectable. • Fixed duplicate dictionary entries that differed only by capitalization. • Fixed lesson and vocabulary generation edge cases that could produce incomplete or inconsistent vocabulary details.

Version 1.0.5 – June 2026 This update improves pronunciation practice reliability, makes account sessions recover more smoothly after server maintenance, makes lesson generation status clearer, and adds more localized text across the app. What's New • Settings now shows the signed-in account email so it is easier to confirm which account is active. • More login, lesson, and learning-flow messages are now localized across supported app languages. Improvements • Pronunciation practice now handles audio recording and playback more reliably on iPhone, including clearer feedback when recording cannot start or analysis needs to be retried. • If pronunciation analysis fails, the result now stays inline with a Retry button instead of showing a popup that has to be dismissed. • Account sessions now recover more reliably when an older sign-in token can be refreshed, reducing cases where users need to sign out and sign back in after backend maintenance. • Lesson generation progress is easier to follow, with better handling for lessons that are still being generated. Bug Fixes • Fixed a pronunciation-practice audio issue that could prevent correct-answer audio, recorded audio playback, or grading from working reliably on iPhone. • Fixed pronunciation scoring so failed AI analysis no longer appears as a real zero score. • Fixed stale sign-in tokens being reused across app environments or server issuer changes when they should be refreshed or cleared. • Fixed cases where generated lesson text could show the wrong localized fallback text. • Fixed cases where lessons could appear stuck in the wrong generation state. • Fixed missing media-asset handling so audio and other saved media references are kept consistent.
