This update guards your saved data: a single corrupt analysis or journal entry can no longer wipe your entire history, unreadable data is backed up before anything overwrites it, and custom recipes survive a bad read. Your history, journal, and recipes have also moved to a sturdier database — migrated automatically, no action needed — and the old 50-analysis history cap is gone, with images now loading on demand so history stays fast as it grows. And two calibration fixes keep your measurements honest: pinch-zooming the ruler photo no longer throws off the measured distance, and particle sizes are no longer inflated on scaled calibration images.

This update sharpens grind-analysis accuracy. The median grind size (D50) now reads true instead of being pulled toward the occasional oversized fragment, your shape-quality settings now take real effect, and photos imported from your library are measured exactly like camera captures. It also tightens reliability across Settings, modal screens, and the brew timer — with safer resets, sliders that save dependably (including with VoiceOver), and extraction-math and stability fixes for more dependable readings.

Grind analysis is now more accurate, with smarter noise filtering, consistent size metrics across screens, and a new low-resolution warning to keep your calibration honest. The brew timer now keeps perfect time even after long stretches in the background, with new haptic feedback at each step. Plus a wave of reliability fixes across the camera, brew journal, and timer for a smoother, crash-free experience.
