Shark Tooth Spotter

Point your iPhone camera at wet shell beds or tide lines. The app highlights tooth-like shapes and learns from examples you label in the field.

Adaptive AI warming up.

What the AI uses

  • Built-in tooth-shape pattern recognition for initial candidates
  • Only the top five probability candidates are locked on screen
  • Your labeled “tooth” and “not tooth” examples
  • Local on-phone learning; camera frames are not uploaded
  • Probability filtering from 50%+ through 90%+

Field tips

  • Use bright indirect light; avoid harsh glare.
  • Wet sand often gives stronger contrast.
  • Move slowly; pause over numbered locked boxes.
  • Tap a numbered box, then choose Tooth or Not tooth from the popup.
  • Tap “Calibrate sand” when lighting changes.

Assistive AI pattern recognition only — not a guarantee. The app learns from examples you label on this phone; it does not scrape copyrighted sources or upload camera footage. Always visually confirm finds before collecting, and follow local beach fossil rules.
