v1.2.1

What's Fixed

• Splash screen logo now matches the app icon (clock on burgundy→pink gradient). Previously the Android TWA splash was still showing the Bubblewrap default green flower-C while the launcher icon already showed the new logo.

Install this APK to replace v1.2.0 and get the updated splash screen.

v1.2.0

What's New in v1.2.0

Chart view

• Dates above each stamp instead of redundant day-of-cycle numbers (already shown in the topmost header row)
• Click empty days in active cycles to back-fill missed observations — the clickable range now extends to today, not just to the last observation
• Print / Save PDF button in the chart toolbar, with print-specific styling for a clean landscape layout
• Save Image button to export the chart as a PNG (via html-to-image)

App icon

• Android launcher icon and PWA icons now match the favicon (white clock on burgundy→pink gradient) instead of the Bubblewrap default green flower-C
• scripts/generate-icons.js now emits Android mipmaps too, so regenerating stays in sync

Install this APK to pick up the new launcher icon on Android.
