Lensgrade 1.3 adds a Shot Diagnosis, full EXIF display, and library stats. - Shot Diagnosis: every result now shows the single most likely reason a frame is soft - camera shake, focus miss, or extreme exposure - with a plain-English tip to fix it on the next shot. - Quantified shake: when EXIF data is present the shake card shows the actual shutter speed used vs the safe threshold and how many stops off it was (e.g. "1.5 stops too slow · used 1/40 s, needed 1/130 s"). - EXIF panel: focal length, 35mm equivalent, shutter speed as a clean fraction, aperture, and ISO are shown for every scored photo that carries metadata. - Library stats: the History tab now opens with a keep rate, average composite score, and a star-distribution bar so you can track how your shooting is improving over time. Existing scores are preserved. Everything runs on device - no account, no tracking, no in-app purchases.

Focus Map: a toggleable on-photo sharpness heatmap on the result screen. Tiles tint cool (soft) to warm (tack sharp) so you see exactly where focus landed; the sharpest region is outlined and labelled 'Focus peak here', and for portraits it tells you whether focus is on the subject or missed it. Plus a new Learn guide, 4 glossary terms, faster/leaner batch scoring (downscaled face detection + per-photo memory pooling), an honest 'couldn't save' warning in Settings, and several internal correctness fixes.

Lensgrade 1.1 is a major on-device upgrade. Subject-aware sharpness scores the face or subject region, not just the whole frame; an exposure and histogram check flags clipped highlights and shadows; a camera-shake check reads EXIF focal length and shutter speed and applies the reciprocal rule to tell shake-soft from focus-soft; a combined keeper-or-cull verdict with a transparent breakdown of every signal; batch now groups frames into bursts and crowns the best pick; searchable, sortable history with re-openable saved batches and CSV export; and a new Learn tab (glossary, guides, crop-factor table, typical score ranges), all offline. No account, no tracking, no in-app purchases.
