1. Introduction

What is Iron Stag?

Iron Stag is an AI-powered deer analysis application designed for hunters, wildlife enthusiasts, and deer management professionals. Using advanced artificial intelligence and machine learning, Iron Stag analyzes photos of deer to provide:

  • Age Estimation - Estimated age of the deer in years
  • Sex Identification - Buck or Doe classification
  • Species Type - Whitetail or Mule Deer identification
  • Antler Analysis - Point count (left and right antlers separately)
  • Body Condition Assessment - Overall health evaluation
  • Harvest Recommendation - AI-powered HARVEST or PASS recommendation
  • Confidence Score - Calibrated confidence for age and recommendation
  • Regional Calibration - Confidence adjusted for your hunting region
  • Favorites & Tags - Organize scans with favorites and custom tags
  • Feedback Labels - Optional accuracy feedback to improve the model
  • Offline Queue - Save scans offline and upload automatically when online
  • Cross-Device Images - Optional cloud image access when enabled

Supported Deer Species

Iron Stag is specifically designed for:

  • Whitetail Deer
  • Mule Deer

The app will not analyze:

  • ❌ Elk
  • ❌ Moose
  • ❌ Other wildlife (hogs, turkey, etc.)
  • ❌ Non-animal images

If you upload an image that isn't a Whitetail or Mule Deer, the app will notify you and no scan will be used.

5. Home State & Regional Calibration

Why Set Your Home State?

Deer vary significantly by region. A 3.5-year-old buck in Texas looks different from one in Wisconsin. By setting your Home State, Iron Stag calibrates its confidence scores specifically for your region's deer population.

Benefits of Regional Calibration

  • More Accurate Confidence Scores - Calibrated for your region's deer characteristics
  • Better Age Estimates - Accounts for regional body size variations
  • Honest Uncertainty - When the AI is unsure, it tells you clearly

Setting Your Home State

Your Home State is prominently displayed in your Profile:

  1. Go to the Profile tab
  2. Find the Home State card (near the top)
  3. Tap to open the state selector
  4. Scroll or search for your state
  5. Tap your state to select it
  6. Your selection is saved automatically

Regional Calibration Zones

Iron Stag groups states into calibration regions:

| Region | States | |--------|--------| | Midwest | IA, IL, IN, KS, MI, MN, MO, NE, ND, OH, SD, WI | | Southeast | AL, AR, FL, GA, KY, LA, MS, NC, OK, SC, TN, VA, WV | | Northeast | CT, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VT | | Plains | CO, MT, NM, WY, UT, ID, NV, AZ, WA, OR, CA | | South Texas | TX | | Northern | AK |

Per-Scan Location Override

If you're hunting in a different state than your home state:

  1. On the Scan screen, look for "Hunting Location"
  2. Tap to select the state where you're currently hunting
  3. This overrides your home state for this scan only
  4. Your home state remains unchanged for future scans

6. Scanning Deer

How to Scan

Navigate to the Scan tab (center icon) to analyze a deer.

Method 1: Take a Photo

  1. Tap "Scan Deer" or "Open Camera"
  2. Point your camera at the deer

Best Practices for Accurate Results

For the most accurate analysis:

✅ DO:

  • Use clear, well-lit photos
  • Capture the deer from the side (broadside view)
  • Include the full body if possible
  • Ensure the deer is in focus
  • Take photos during daylight or with good artificial lighting
  • Set your home state for calibrated results

❌ DON'T:

  • Use blurry or out-of-focus images
  • Upload extremely dark photos
  • Use images where the deer is too far away
  • Submit photos with multiple deer (AI may get confused)
  • Upload photos of mounted/taxidermy deer

7. Scan Results

Understanding Your Results

After a successful scan, you'll see:

Primary Information

| Field | Description | |-------|-------------| | Deer Type | Whitetail or Mule Deer | | Sex | Buck, Doe, or Unknown | | Estimated Age | Age in years (e.g., 3.5 years) | | Recommendation | HARVEST (green) or PASS (red) | | Confidence | AI certainty percentage (0-100%) |

Understanding Confidence Scores

Iron Stag uses a calibrated confidence system:

  • High Confidence (70%+) - The AI is confident in its assessment
  • Moderate Confidence (50-70%) - Reasonable certainty, but some uncertainty
  • Low Confidence (<50%) - The AI is uncertain; consider this a rough estimate

Age Uncertain Indicator: When confidence is low, you may see "Age Uncertain" displayed. This means the AI acknowledges it’s not sure about the age estimate.

Confidence Breakdown: Some results show separate confidence for age and recommendation.

Antler Details (Bucks Only)

| Field | Description | |-------|-------------| | Total Points | Combined antler points | | Left Antler | Points on left side | | Right Antler | Points on right side |

Additional Information

| Field | Description | |-------|-------------| | Body Condition | Health assessment (Excellent, Good, Fair, Poor) | | Reasoning | AI's explanation for the recommendation | | Region | The calibration region used for this scan (if enabled) |

14. FAQ

General

Q: Is Iron Stag accurate? A: Accuracy varies with image quality and conditions. Use the confidence score as a guide, not a definitive determination.

Q: Does it work offline? A: AI analysis requires internet, but scans can be queued offline and uploaded automatically when you’re back online.

Q: Can I use trail camera photos? A: Yes! Trail camera photos work well, especially if they're clear and well-lit.

Q: Why should I set my home state? A: Setting your home state enables regional calibration, making confidence scores more accurate for deer in your area.

Scanning

Q: Why was my scan rejected? A: The AI only analyzes Whitetail and Mule Deer. Photos of other animals or non-animal images will be rejected.

Q: How long does analysis take? A: Typically 5-15 seconds depending on your connection speed.

Q: Can I scan the same deer twice? A: Yes, each scan uses one of your scan credits.

Q: What does "Age Uncertain" mean? A: When the AI's confidence is low, it honestly tells you it's uncertain about the age estimate. Use such results as rough guidance.

Subscription

Q: Do free scans refresh? A: No. Free users get 3 lifetime scans. Once used, upgrade is required.

Q: Can I get a refund? A: Refunds are handled by Apple/Google according to their policies.

Q: What happens if I cancel? A: You keep access until the end of your billing period, then revert to Tracker tier.

Q: What's the difference between monthly and annual? A: Annual ($89.99/yr) saves you 0 compared to monthly ($9.99/mo × 12 =

19.88/yr).

Privacy

Q: Do you store my photos? A: Photos are stored locally. If cloud image storage is enabled, a compressed copy may be stored for cross-device access.

Q: Can I delete all my data? A: Yes. Use "Delete Account" to permanently remove all data.

Biometric Login

Q: How do I enable fingerprint/Face ID login? A: First login with your password, then go to Profile → Security and toggle on biometric login.

Q: Why isn't biometric showing on my login screen? A: You must enable it first from Profile → Security. It also requires a native build (not Expo Go).

Q: Is biometric login secure? A: Yes. We store a secure encrypted token, not your password. Only your biometric can unlock it.
