Whitetail · Mule deer · Elk · Pronghorn

What does your buck, bull or antelope score?

GreenScore gives you an AI estimate of a green score from a few photos, for whitetail, mule deer, elk and pronghorn. It is an estimate, not an official score: for whitetail it is typically within about ±15″ of a tape measurement and comes with an estimated age and a next-season projection. Want to tape it yourself? The step-by-step calculator is free.

Everything in one place

AI estimate · Pro A green score from your photos Take up to three photos, straight-on first (add a side angle for a tighter read). The app recognizes the animal, blacktail included, or you pick it: whitetail, mule deer, elk or pronghorn. You get an estimated score labelled AI estimate with its typical margin (about ±15″ for whitetail), plus tips when a retake would help.

Whitetail · AI estimate · Pro Age class & next-season growth For whitetail, alongside the score you see an estimated age class (for example 3.5–4.5 years) and a rough projection of where the rack could score next season. Both are model estimates from the antlers, not exact ages or guarantees.

Free Step-by-step calculator Tape it yourself: antlers for whitetail, mule deer and elk, or horns for pronghorn, entered one measurement at a time in eighths of an inch. The totals are added up for you, with deductions and net for antlers. No limit, no subscription.

Free Community map & feed Browse deer harvest statistics published by wildlife agencies, season dates and short news summaries, with sources and dates listed in the app, plus state and province totals from GreenScore users. “Count my buck on the map” applies to whitetail AI estimates and is on by default. We receive the state or province (and a county, if you pick one) and the score; other users see only totals. You can switch it off at any time.

Whitetail & mule deer Hunt Forecast An hour-by-hour hunt rating for the next 7 days in the U.S. county or Canadian census division you pick (no GPS), based on the time of day, rut timing and the weather. It is an estimate, not a guarantee. Today's rating, the 7-day weather, the rut phase and rut alerts are free; ratings for all 7 days and the hourly view need Pro.

Keep & share Trophy card & trophy room Turn a score into a clean card for the group chat, and keep every trophy in your trophy room with the date, state and your own notes.

How it works

Estimates only. Not affiliated with or endorsed by the Boone and Crockett Club, the Pope and Young Club or Safari Club International. Official scores require a certified measurer after the 60-day drying period.
