5. Home State & Regional Calibration

Why Set Your Home State?

Body appearance and seasonal context can vary by region. Setting your Home State supplies regional context used by Iron Stag's confidence calculation; it does not confirm the age estimate.

Benefits of Regional Calibration

• Regional context - Associates the scan with the configured calibration region
• Separate uncertainty - Results can show confidence or withhold an age when cues are insufficient

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

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) |

Manual Unofficial Boone and Crockett Workflow

This workflow is separate from AI deer analysis and is available for harvested buck records. Iron Stag does not infer rack measurements or a Boone and Crockett score from the photo.

• The user selects Typical or Non-Typical for the matching Whitetail Deer or Mule Deer record.
• The user manually enters physical antler measurements in whole inches and eighths.
• The app organizes the measurements and calculates the guided worksheet totals.
• The saved result is unofficial and is not a certified Boone and Crockett score.

Editing Scan Results

If you believe the AI made an error, you can edit and re-analyze:

1. Tap the Edit button (pencil icon) on the scan result
2. Modify any of the following:

• Sex (Buck/Doe)
• Deer Type (Whitetail/Mule Deer)
• Left Antler Points
• Right Antler Points

1. Tap "Re-Analyze"
2. The AI will recalculate using your corrections

14. FAQ

General

Q: Does Iron Stag guarantee an accurate age? A: No. Photo quality, angle, obstruction, posture, season, and visible body cues affect the estimate. Use confidence and reasoning as context, not proof of biological age.

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, when one Whitetail or Mule Deer is clearly visible. A level, broadside, full-body frame generally exposes more useful aging cues than a distant, blurred, obstructed, or sharply angled image.

Q: Why should I set my home state? A: The selected state supplies regional context to the confidence calculation. It does not confirm the estimated age.

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: Processing time varies with the image, connection, and service conditions.

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.

Q: Does Iron Stag calculate a Boone and Crockett score from the photo? A: No. The AI photo analysis and the manually guided unofficial scoring workflow are separate. The user enters physical measurements for a harvested buck.

Q: Which unofficial score types are available? A: Typical and Non-Typical workflows are available for Whitetail Deer and Mule Deer. The result is not a certified Boone and Crockett score.

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 are the subscription prices? A: Reference U.S. prices are $9.99 monthly and $89.99 annually. The App Store or Google Play shows the final regional price before purchase.

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: What does biometric login store? A: The app uses the device biometric prompt to protect a locally stored authentication token; it does not store the biometric itself.
