• Portable Keeper Desk backups: save previews, decisions and notes, then restore as a separate session. • Searchable review queue with decision filters and next-match navigation. • Undo your most recent saved comparison edit. • Improved text contrast, Dynamic Type and iPad readability. • Preserved recovery copies when score history cannot be read, confirmed individual score deletion, and a haptics setting that is respected. • A refreshed lens icon and lighter field-reference cards. • Fixed inflated sharpness measurements; earlier scores are marked for re-analysis. • Removed unsupported scene ranges and print-quality claims, and clarified sample content and analysis limitations.

A clearer App Store name and search details. No other changes in this update.

Keeper Desk Keeper Desk adds saved photo comparison sessions with linked detail controls, your own keep/maybe/pass decisions, and a shortlist contact sheet. 1. Open Keeper Desk from the Score tab. Try the clearly labeled five-photo example or choose 2–12 still photos. 2. Choose the two frames to compare. Use linked zoom and relative crop controls, optionally hide names and prior decisions, then mark side B Keep, Maybe or Pass and record a reason. 3. Resume the saved session, revisit undecided frames, and preview the contact sheet of kept photos. Share its PDF with a CSV containing all decisions, notes and source hashes. Decisions are manual. Linked crops do not align subjects or measure focus. Saved JPEG previews have a maximum 2560-pixel long edge and are not original-resolution inspection or original exports. Single still inputs up to 32 MB and 120 megapixels; 2–12 photos per session, 10 sessions and 120 MB of saved data. Original Photos items are never edited or deleted.

Lensgrade 2.1 adds a no-permission sample workflow, a source-backed Field Lab, and a next-shot plan on every result. - Try sample photo: the Score tab can analyze a bundled image with the same production pipeline, so new users and reviewers can see a full result before opening Photos. - Rank sample roll: the Batch tab can score a bundled five-photo roll and show the ranked keeper workflow immediately. - Field Lab: Learn now includes 16 offline technique cards with source links covering Laplacian sharpness, focus maps, subject ROI scoring, shutter safety, histograms, depth of field, low light, EXIF audits, and CSV review. - Next-shot plan: Result now turns diagnosis into practical actions such as faster shutter, highlight protection, subject focus, or repeatable test steps. Existing scores are preserved. Core scoring remains on device with no account, no tracking, and no in-app purchases.

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.
