Features

Everything in the beta, enumerated. No roadmap padding — if it's listed, it ships.

The full list
Open & browse
Instant openClick any folder and the grid appears immediately — no import, no indexing, no database build. Thumbnails stream from embedded previews.
Folder-nativeYour folder structure is the organization. Browse drives and folders exactly as they exist on disk, local or external.
Browser-style tabsMultiple contact sheets at once. ⌘T new, ⌘W close, ⌘1–9 jump, ⌘←/→ cycle. Background tabs freeze — zero work until activated.
RAW+JPEG pairingSame-name pairs collapse to one grid item, badged R+J.
CR3-aware decodingFull-resolution embedded JPEGs pulled straight from Canon CR3s. External drives get dedicated decode lanes; memory cards are treated gently.
Find
⌘F, from anywhereOne keystroke searches frames in the open folder and folders across every mounted drive.
Frames by numberType 4021 and jump straight to IMG_4021 in the grid. Suffix digits are enough.
Folders by nameType a job name and the folder surfaces from any drive, Spotlight under the hood. Enter opens it in a tab; ⌘Enter reveals it in the sidebar.
Recents firstFolders you've worked in float to the top before you finish typing.
Cull
Keyboard-first rhythm1–5 stars, ⌃1–5 color labels, X reject, 0 clear. In expanded view every rating auto-advances to the next frame.
Color-first modePress ` to flip the scheme: 1–5 become color labels, ⌃1–5 become stars.
Lightroom-matched filtersStar threshold with at least / exactly / at most, color-label filters including "no label," rejects view. Same vocabulary, zero translation.
Expanded viewFull-window preview: Z to 100%, scroll zoom, drag pan, resizable filmstrip, RGB histogram with clipping warnings, full EXIF.
Survey modeS compares 2–4 frames side by side with synchronized zoom — scroll on one and all zoom to the same spot. The sharpest frame wears the crown.
Selection-scoped reviewSelect ten photos, hit Space — expanded view contains exactly those ten. Arrows and filmstrip never leave your set.
See what the camera saw
Face triageEvery face cropped and graded — eyes open, squinting, or closed. Smile-aware, so a laughing kid doesn't torpedo the frame. Click any face to zoom to it at 1:1.
Group-shot rescueSmall faces in big groups get a second high-resolution analysis pass — back-row eyes graded from real detail, not noise.
Focus scoreSharpness measured on the subject's face, not the whole frame. A crisp portrait against creamy bokeh scores high.
All on-deviceEvery analysis runs locally. Your photos never leave your Mac.
Files, safely
Originals never touchedRatings and labels write to standard XMP sidecars — Lightroom, Capture One, and Photo Mechanic read them natively. Culls made elsewhere are adopted on open. Foreign sidecars are never overwritten.
Finder-grade file ops⌘C/⌘X/⌘V photos between folders — sidecars travel too. Drag selections onto sidebar folders to move. Copies and moves carry their ratings. Everything undoable.
Rejects go to TrashNever deleted in place. Rename in-grid, rotate losslessly with [ and ].
Card ingestMemory cards are read-only to f/uno. Ingest copies to your drive — the card is never modified.
Folder templatesOne click builds your standard shoot structure (RAW / selects / exports / …) exactly the way you like it.
Ingest
Insert and goCard in, sheet up: photo count, size, first frames, and a free-space verdict. Enter starts the copy and opens the landing folder, thumbnails pouring in live.
Knows whose cameraThe photographer is recognized from the camera serial baked into every frame. Card two of the night is insert, Enter.
Per-shooter foldersMixed cards split by camera body into each shooter's numbered folders. Re-inserted cards top up instead of duplicating.
Second copyPoint ingest at a backup drive and every frame lands on both, each drive with its own space verdict. It warns if the backup shares the main drive.
Rename on copyPatterns with sequence, import number, date, and original-name tokens, previewed live before a single file moves. RAW+JPEG pairs never split.
Honest ejectIf the card won't release, f/uno names the app holding it instead of shrugging.
