Lessons for your level Choose a level from A1 to C2 when you set up a language or update your preferences. Lesson cards now show a level, where available, instead of a time estimate. The words you study now come from the lesson's dialogues and exercises, with examples suited to your level. Hear the right pronunciation When a word has more than one pronunciation, see which one goes with each meaning. You can listen and practice with audio where available. Edit your request and try again If we couldn't create your lesson, you can edit your original request and try again. You'll also get a clearer message if we didn't understand what you wanted to learn. Also in this update - Choose Marin or Cedar for your language companion. If you previously used another voice, your companion will use Marin. - Hawaiian and Louisiana French are now marked Experimental. - Updated dictionary entries, with clearer prefix and suffix labels. - Better word breaks in sentence-building exercises. - Lesson lists catch up after you reconnect when older lessons have been replaced. - Tidier chat spacing and fewer gaps around the keyboard.

Follow your lesson progress more easily, enjoy more reliable chats and notifications, and explore clearer vocabulary explanations. What's New • Vocabulary cards distinguish expressions, phrases, and idioms, with language-specific grammar details such as verb classes, noun gender, and transitivity when available. • Separate culture and usage notes make customs, grammar, formality, and word combinations easier to find. • A new lesson completion screen recaps what you studied and lets you continue to quizzes or leave the lesson. Improvements • Overall lesson progress combines reviewing content (25%) with completing quizzes (75%). • Pronunciation display preferences stay consistent between lesson cards. • Previously loaded chats appear from your device cache while connecting, with earlier reply feedback and fewer repeated background requests. • Lesson notifications open through the normal lesson and download flow. The inbox marks entries as read but keeps them until you clear them. • Notifications for languages you no longer study provide guidance and a route to language settings. • Find lesson notifications in the account menu and create new lessons from empty lists or list footers. • Better visibility of phone status-bar, pull-to-refresh placement, and background transitions. • Lesson generation can use broader, language-specific vocabulary frequency and level evidence. • More consistent language companion wording and study guidance. Bug Fixes • Pending lesson-generation cards now survive navigation and app restarts without disappearing during temporary connection failures. • Improved recovery of missed chat updates and fixed deleted messages reappearing from an old cache. • Notification clearing is saved more reliably, including failed requests and account changes. • Recognized grammatical subtypes no longer appear as Other or Unknown, and noun/verb classifications preserve the selected meaning. • Account-policy checks distinguish connection problems from policy requirements and handle retries more safely.

Find words faster, get started more easily, and enjoy smoother lessons in this update. What's New • Search the dictionary using the word you are learning or a translation or meaning in your native language. • Review updated terms and privacy policies directly in the app. • Dismiss active maintenance notices after reading them. Online features remain unavailable until maintenance ends, and updated notices may appear again. Improvements • Clearer sign-in steps, email validation, and password recovery. • More reliable account switching, with saved preferences and setup handled more consistently. • A clearer Resume action and less repeated information on the lesson map. • Smoother lesson browsing and progress updates. • More reliable recovery when lesson creation is interrupted, preserving your planned exercises.

This release improves multilingual text rendering throughout RADLing, adds clear scheduled and active maintenance handling, fixes Google sign-in returning to the app on iPhone and iPad, and makes password recovery more reliable. What's New • RADLing now shows advance notices for scheduled maintenance, including the window in the device's local time and any message supplied by the service operator. A scheduled notice can be dismissed and appears again if the schedule changes. • Active maintenance now has a persistent in-app notice. • Text throughout lessons, quizzes, chat, translation, dictionaries, flashcards, notifications, onboarding, and settings should now be rendered correctly, particularly for Asian scripts. Improvements • Japanese, Korean, Mandarin, Cantonese, and Thai text now uses locale-aware, fallback-safe typography that avoids uneven synthetic bold glyphs and inappropriate letter spacing. Greek and Cyrillic content also receives more reliable locale selection. Bug Fixes • Fixed Google sign-in on iPhone and iPad sometimes leaving the user on the callback page after authentication. • Fixed password-recovery links being handled inconsistently. • Fixed valid password resets being able to fail. • Fixed mixed-language text sometimes inheriting an incompatible app locale, which could select the wrong Chinese, Japanese, or Korean glyph form or produce inconsistent weight and spacing.

This release makes complete lessons reliably available offline, improves lesson-download and audio reliability, makes notifications more timely and relevant, and strengthens lesson preparation and recovery. What's New • Current and incomplete lessons are automatically prepared for offline use. When a ready package is available, it contains lesson content, audio, and supported quizzes. Completed lessons that were never installed remain online-only until Download lesson is selected. • Downloaded lessons open without a network connection. Progress, grades, quiz results, and completion are saved locally and synchronized after reconnecting. Tutor chat and other AI-powered actions still require internet access. • Downloads proceed automatically on Wi-Fi and, when under 10 MB, on cellular data. Larger cellular downloads require confirmation, and interrupted downloads can resume when the server supports ranged downloads. Improvements • Lesson updates are discovered at startup, after reconnecting, when returning to the app, and periodically while the app remains open. An installed lesson stays usable until its replacement is completely downloaded and verified. • Completed downloads that have not been opened for 30 days may be removed automatically to recover storage. Current lessons and their active progress are protected. • Tutor-reply and lesson-ready banners are suppressed only while their exact chat, lesson, quiz, or matching lesson list is already visible. Suppressed items are marked read, while unrelated notifications continue to appear. Bug Fixes • Fixed the Add New Lesson button and lesson-creation window sometimes taking several seconds to appear. Both now respond immediately while lesson availability checks finish in the background. • Fixed lesson lists repeatedly reloading or flashing between disconnected and connected during brief server interruptions. Transient gateway errors are now verified before showing an outage, reconnect refreshes are throttled, rapid lesson updates are combined into one refresh, duplicate availability checks are avoided, and the incomplete-lesson creation limit is enforced correctly. • Fixed startup database warnings before sign-in, a rare chat-history error when leaving the page while it was loading, and stale downloaded lessons failing to save their last-opened time locally. • Quiz resume state is tied to the exact downloaded content version so progress is not applied to changed questions after an update. • Improved lesson-audio publication for multiline text and validated lesson-catalog phrases flagged by moderation that could previously prevent an otherwise valid lesson from becoming downloadable. • Fixed early lesson-generation failures being able to leave a lesson permanently stuck instead of resuming from its saved request. • Fixed missing issues with lesson generation around Louisiana French due to missing vocabulary seeding. • Fixed sentence-structure quiz explanations and alternative notes appearing in the target language. Learner-facing grammar guidance is now generated in the mother language, while target-language text remains available as examples. • Fixed translation quiz context and grading feedback changing language with the prompt direction. Both now remain in the learner's mother language whether the prompt is in the mother language or the lesson's target language. • Fixed lesson-practice dialogs that could appear without a concrete title or situation summary. Every lesson dialog now includes both in the learner's mother language; dialog quiz questions and answers are unchanged.

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.
