"Water shapes its course according to the nature of the ground over which it flows." This update brings hand-drawn typography and smoother day-to-day interactions:
• Hand-Drawn Numbers: Numeric text across the app, widgets, and Live Activity now uses custom hand-drawn typography with no glyph clipping.
• Hold-to-Drink Refinement: Added tap prevention so accidental taps won't log water; includes subtle haptic ticks once the hold threshold is reached.
• Traditional Chinese & Korean: Added full localization support for Traditional Chinese and Korean, including widget galleries.
• Day Rollover & Health Sync: Improved midnight day rollover for widgets and fortified Apple HealthKit synchronization.
• My Other Apps: Added a showcase in Settings to explore other indie utilities.
Thanks for using WaterGrug — stay hydrated with grug!
