v2.0.1

Changes

• Password confirmation — creating an account now requires entering the password twice
• Save Chart Image moved to Settings > Data Management; uses the Web Share API so it works in Capacitor's WebView (Android share sheet) with fallback to download for browsers
• Print Chart moved to Settings > Data Management; navigates to chart then triggers print
• Chart view is now uncluttered (toolbar removed)

v2.0.0 — Capacitor (no more Chrome limits)

Migrated from TWA to Capacitor

The Android app now runs in an embedded System WebView instead of Chrome. This means Chrome screen-time limits no longer block the app — Android tracks it as a standalone app.

Everything else works the same: the app still loads from creighton.stephens.page, so web updates deploy instantly without new APK releases.

Important: data migration

Upgrading from the previous TWA-based APK to this Capacitor APK will reset local data because storage moves from Chrome's profile to the System WebView's sandbox. If you have an account with server sync, just sign back in and your data will restore automatically. Local-only data (without an account) will not carry over — export it before upgrading if needed.

Other changes since v1.2.1

• Same app icon and splash screen (clock on burgundy gradient)
• Portrait orientation locked
• APK size increased from ~1.1 MB to ~3.8 MB (Capacitor WebView bridge overhead)

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.
