Android 16 readiness, plus fixes for reading Nova that never reached the server.

Changed

  • Android 16 Support - The app now targets API level 36, meeting Google Play's requirement for updates submitted from August 31, 2026

Fixed

  • Nova Loss on Tab Switch - Leaving the reader via Profile or Settings now saves the active session's Nova

0.10.2

July 28, 2026

July 4, 2026

Smarter PDF reading: batch extraction, scanned-PDF detection with automatic Academic Mode fallback, and higher extraction accuracy across languages.

Added

  • Batch PDF Extraction - Select multiple PDFs and extract them in one action; they queue up and process one after another in the background

April 24, 2026

  • Spin Cooldown Bypass - The spin wheel now fails closed while server data is loading, closing the brief post-login window that allowed extra spins
  • Clear Cooldown Errors - The server now returns a specific cooldown error with the exact next-spin time, so the app can sync correctly

0.4.7

March 29, 2026

0.4.5

March 23, 2026

Bug fixes for reading time inflation and spin wheel cooldown bypass.

Fixed

  • Reading Time Double-Counting - Fixed daily reading time incorrectly increasing every time the app was reopened. The useLoadProfileData hook was loading sessions from AsyncStorage and dispatching addSession() on every app start, causing sessions to accumulate exponentially. The redundant hook has been removed
  • Spin Wheel Cooldown Bypass - Fixed the daily spin wheel allowing re-spin before the 24-hour cooldown expires. Backend claimSpinReward now returns nextSpinAvailableAt in all response paths. The client no longer uses a separate AsyncStorage fallback, relying solely on Redux. The error handler now fails closed instead of failing open

0.4.4

March 22, 2026

Critical bug fixes for PDF text extraction on physical devices, addressing stuck progress at 99% and empty extraction issues.

Fixed

  • PDF Extraction Stuck at 99% - Fixed extraction loop never completing if last page(s) had no content. The hasContent check was skipping the analysis phase, causing headingThreshold to never be set

  • Progress Updates - Progress now updates for ALL pages (including blank ones), not just pages with content
  • Academic Mode Bypass - Added pdfMode !== "academic" check in handleBookPress to prevent false "text is being prepared" alert

  • Split-Screen Reader - Removed SplitScreenReader component and split mode UI from ReaderTopBar

0.3.0

March 17, 2026

Critical fix for avatar assignment bug where users were displayed with incorrect high-tier mascots regardless of their actual Nova level.

Fixed

  • Avatar Assignment Bug - Fixed getAvatarIdForNova() in both frontend and backend. The thresholds array was sorted in descending order while MASCOT_AVATARS is sorted ascending, causing avatar IDs to map to wrong mascots
  • Database Correction - All 39 users' avatarId values were recalculated and corrected

0.2.9

March 16, 2026

Critical bug fix for avatar persistence across app sessions.

Fixed

  • Avatar Display Bug - Fixed an issue where the user's selected avatar would randomly change to an incorrect one on app launch. The updateUserProfile reducer now filters out undefined values from server responses, preventing them from overwriting existing avatar data

Floating tab bar improvements with tablet support and avatar ID system refinement.

Changed

  • Tablet Support - Floating tab bar adapts to screen size: centered with fixed width (280px) on tablets, full-width with padding on phones
  • Reduced Size - Tab bar height reduced from 65px to 50px, icon size from 32px to 24px
  • Avatar ID Logic - Reverted to use Nova threshold values for consistent avatar identification across sessions

Fixed

  • Avatar Selection - Avatar IDs now correctly use Nova threshold values ensuring avatar persistence after app restart

0.2.6

0.2.3

March 5, 2026

Nova calculation formula redesigned with time-based linear growth. Fixed a critical bug where scrolling incorrectly awarded Nova points.

Changed

  • Nova Calculation Redesign - Switched from page-based to time-based calculation: Old formula: (pages × 10) + (minutes × 5) + 20. New formula: Linear growth per minute (10, 20, 30... up to 300 Nova/min at 30 min). After 30 minutes: capped at 300 Nova per minute. Example: 30 min reading = 4,650 Nova (instead of unpredictable values)

Fixed

  • Scroll Nova Bug - Fixed incorrect Nova gains when scrolling through pages. Previously, each scroll position change triggered recordPageRead(), causing excessive Nova accumulation
