Reworked purchase and restore: errors are now reported clearly instead of failing silently.

New: Shift Mode. Pick early, late or night, and CaffSense moves your caffeine cutoff to the sleep window that actually follows your shift — based on what you logged and your learned half-life. Each shift can keep its own sleep anchor. Also in this update: the cutoff now shows the date when it falls on another day, and says clearly when it has already passed. App, widget and Apple Watch show the same value throughout.

This update makes CaffSense more reliable and easier to use: clearer purchase and notification states, consistent history and streak calculations, improved what-if planning, and more accurate widgets. It also includes accessibility and localization refinements.

Reduction mode now displays correctly for Pro subscribers who haven't started a weekly target yet. Refined the Today screen layout.

• More accurate cutoff, clean-night, and Typical Day calculations • Clearer confidence labeling and Pro feature indicators • Smoother Quick Log and What-if Planner experience • Small bug fixes and polish

• CaffSense can now be opened via direct links (e.g. from App Store events) • Minor improvements

Improved guidance around your first caffeine-sleep pattern, plus smaller refinements.

Smarter caffeine cutoff: now based on your typical drink and remaining caffeine, with a clear label and time on the chart. Set bedtime manually or automatically from Apple Health sleep, with an easier time picker.
