One app, four tools.

Vizirack helps you judge, score, and keep every animal you chase. Pick a tool below to learn how it works.

№ 01 — No photo needed

Quick Judge

Glass him from the truck or the trail. Compare his rack to his body and tap a few presets, and get a gross score in seconds — the way guides actually call animals.

1

Pick your species

Tap the species button up top. Choose from your quick picks, or open the full list — Quick Judge covers all the deer, elk, moose, caribou, sheep, goat, pronghorn, and exotics.

2

Eyeball the basics

For each measurement, tap the preset that fits — "at ears," "long beam," "to the nose" — or type the inches if you've got a number. You're judging one side; Vizirack handles the rest.

3

Mark the extras

Flag brow tines, non-typical points, and mass (below average / average / above). Skip anything that's just average — only tap what stands out.

4

Read the live estimate

Your gross score updates at the top as you go, with a plain-language read like "Solid mature buck" and the B&C minimum for reference.

5

Save it

Send him to your Trophy Wall if he's down, or your Hit List if he's one you're after.

How the math works

A disciplined eyeball, not a tape job

Quick Judge takes the outside spread you glass, converts it to inside spread, caps it at the beam length (the B&C rule), doubles your one-side reads, and adds mass. It's built to be fast and honest — a bracket, not a measurement. For an exact number, put him through Score Sheet once he's on the ground.

Best for

Calling animals while you're glassing, comparing two bucks fast, and stocking your Hit List before the season. It's rough by design — when precision matters, reach for Rack Read (a photo) or Score Sheet (a tape).

№ 02 — Full workup

Score Sheet

Got him on the ground? Enter every measurement and Score Sheet runs his numbers against the B&C, P&Y, and SCI formulas at once — gross and net. It does the math; you bring the tape.

Read this first

This is your score — not an official one

Vizirack isn't a certified scoring body. Score Sheet calculates a self-measured ("green") score using the published B&C, P&Y, and SCI formulas. It's perfect for the day of the hunt and for knowing where he stands — but it isn't an official entry. For the record book, a certified measurer takes the score after the mandatory 60-day drying period.

1

Pick species & category

Choose the animal and whether you're scoring it typical or non-typical — that determines which measurements show up.

2

Enter measurements to the 1/8"

Type the whole inches and tap the eighths for each field — beams, spread, tines, circumferences, abnormal points. The form shows only what your species needs.

3

Add the details

Attach up to three photos, plus name, date, location, and notes — so the full record lives with the score.

4

Read your numbers

See net and gross for B&C / P&Y, plus an SCI figure, with an award badge if he clears a minimum.

5

Save it

Store him on your Trophy Wall with every measurement intact.

Net vs. gross

Gross is the raw total. Net (for B&C / P&Y) deducts for side-to-side asymmetry — so a buck with mismatched sides nets lower than gross. SCI sums everything without asymmetry deductions, which is why the SCI number often reads higher. All three are calculated from the same measurements at once.

№ 03 — AI photo scoring

Rack Read

Upload a photo and the AI identifies the animal, counts points, and returns a gross score in seconds. On a clean photo of a typical mature animal it usually lands within a few percent of the measured score — bigger trophy-class animals run wider, and it tells you when to grab a tape. We're always improving the models, adding species, and refining the read.

Get a photo that scores well

The AI sizes the antlers against the animal's anatomy — mainly the ear. A clean look at the rack and a visible ear is what earns a tight, high-confidence read.

+ Do this
  • 01Shoot a three-quarter angle (30–45°) — both sides of the rack, nose turned slightly toward you.
  • 02Keep one ear fully in frame, base to tip. That's the ruler the AI scales with.
  • 03Get the whole rack in frame — every tine, both beams, the spread.
  • 04Use soft, even light — overcast, open shade, golden hour.
Avoid this
  • 01Dead-on or pure side shots that hide the ear.
  • 02Tines or beam tips cropped off the edge.
  • 03Harsh backlight or a silhouette against the sky.
  • 04Distant shots where the rack is small or soft.

How it works

1

Choose your mode

On Animal for a live or trail-cam shot, or Shed Antler for a shed — single side, or a matched pair for a real two-sided score.

2

Upload your photo

Trail cam, phone, or digiscope — all work. Add a second angle first if you want a tighter read.

3

Get the score

The AI detects the species (correct it with one tap if it's off), counts points, and returns your numbers.

4

Refine if you can

Feed it anything you actually know — a measured spread, a drop tine, "bigger than my 178 last year" — and it re-reads with your input.

5

Save it

To the Trophy Wall or the Hit List.

Reading your results

Class Number
The headline figure, rounded to the nearest 5 — "a 175-class buck," the way hunters talk. A gross B&C-style estimate.
Range
The low-to-high window he likely falls in (e.g. 170–180). Often the most honest single answer.
Confidence
How sure the AI is, with a ± figure. Driven mostly by photo quality and angle.
Point Count & Frame
The count in hunter language — "5x5 bull," "4-point buck," "10-pointer" — plus frame configuration.
The Read
A guide-voice write-up of frame, mass, beam, and tine height, with specific observations you can check against your own eyes.

Confidence levels

High

Clean photo, good angle, ear and rack visible. Trust the Class number.

Medium

Some limitation. Lean on the range more than the exact number.

Low

Tough photo. Treat it as a ballpark, add an angle, or re-shoot.

The honest part

Why it isn't always perfect

Antlers don't come with rulers attached. Every hunter, guide, and scorer estimates from reference points and experience — Rack Read does the same thing, just at scale and in seconds. Because it works from a photo, not a tape, two shots of the same animal can read a little differently — one angle shows mass better, another hides a tine. That's why the range and confidence matter more than the exact number. And every score a hunter confirms with a tape makes it sharper over time.

Rack Read's AI scoring is dialed in for mule deer, whitetail, and American elk (beta). For anything else, use Quick Judge or Score Sheet.

№ 04 — Trophy Wall & Hit List

Trophy Room

Every animal you score lives here, in two views: the Trophy Wall for animals you've taken, and the Hit List for the ones you're still after.

WALL

Trophy Wall

Every buck, bull, and ram you've put your hands on — score, photos, location, date, all kept where you can find it.

HIT LIST

Hit List

Targets for the season. Score one with Quick Judge or Rack Read, save him to the Hit List with a season year, and go hunt him.

MOVE

Mark Harvested

Got him? From his detail page, move him off the Hit List onto the Wall with a harvest date. The history follows.

Organize the wall

Sort by score, date, or name. Group by species or year. Filter by tags you create — "2026," "South unit," "shooters," whatever you want. Find any animal in seconds.

Every animal's detail page

Tap any animal to see the full record. Edit the name, date, location, and notes; add up to three photos; manage tags; move him between the Wall and Hit List; or delete him. It's all cloud-backed and synced across your devices, so your wall is the same on your phone and your laptop.

Good to Know

What a score is — and isn't

Quick Judge and Rack Read give you gross-score estimates — no deductions, the way guides call animals in the field. Score Sheet calculates a full self-measured score against the official formulas. All three are built to help you judge and decide, not to certify a record.

An official B&C, P&Y, or SCI score requires a certified measurer with the antlers in hand, after the 60-day drying period. Vizirack's numbers and an official entry will rarely match to the inch — use Vizirack for the field and the wall, and a certified measurer for the record book.

FAQ

Frequently asked questions

Which tool should I use? +
Glassing in the field with no photo → Quick Judge. Got a photo or trail-cam shot → Rack Read. Animal on the ground with a tape → Score Sheet. All three save to your trophy room.
How accurate is Rack Read? +
On a clean, well-angled photo with the ear visible, it's tight on typical mature animals — usually within a few percent. Very large or trophy-class animals are harder to size from a photo and read wider, so it flags those as lower confidence and tells you to confirm with a tape. Always read the confidence alongside the number.
Is Score Sheet an official score? +
No. It calculates a self-measured ("green") score using the published B&C, P&Y, and SCI formulas. It's great for knowing where an animal stands, but an official entry needs a certified measurer after the drying period.
Can I score velvet or trail-cam photos? +
Yes. Velvet and trail-cam shots are fully supported — just expect lower confidence on soft or night-IR images. Shed scoring is coming soon; for now Rack Read works on animals with the rack still on.
Do my free Rack Reads reset? +
No. The 3 free Rack Reads are a one-time, lifetime allotment. Paid plans (Vizirack AI, Pro) refresh once a year on your billing date. Quick Judge and Score Sheet are always unlimited.
Can I buy reads without a subscription? +
Yes. If you don't want a yearly plan, grab a one-time pack of 25 AI Rack Reads for $19.99. There's no subscription, and the reads never expire — use them this season or whenever you need them. You'll see the option when you run out of free reads, or any time on the plans page.
