About Shark Tooth Finder: Fossil ID
Point your camera at the sand — AI spots shark teeth in real time, right on the beach. Know when to go: NOAA-quality tide times and a daily Shark Index that grades every low tide. From Venice Beach, FL to Calvert Cliffs, MD — hunt smarter and find more fossils. WHY SHARK TOOTH HUNTERS USE THIS APP • AI CAMERA — Live detection highlights shark teeth in the shell hash as you scan. Or snap a photo of any find for an instant check. • SHARK INDEX — One score for "is today worth the drive?" It combines the year's top negative tides, post-storm sand movement, and time-of-day grades into a simple rating. • TIDE & LOW-TIDE TIMES — NOAA-quality tide predictions with exact low-tide windows, so you arrive when the most beach is exposed. • FIELD GUIDE — 27 fossil teeth with real photos: megalodon, great white, mako, tiger, sand tiger, Ginsu, the false mako, and the lookalikes that fool everyone. Each card shows how to tell it apart, how big it runs, and where it turns up. Tap any photo to zoom in on the serrations. You tag your own finds — the app never guesses the species for you. A new family-tree tab shows the 9 groups of sharks alive today with a representative tooth each, plus essays on fossil vs modern teeth and on rinsing, desalting and storing your finds. • LEARN AS YOU GO — A bedrock card for every find (what rock is under your feet, how old that sea was, which sharks are recorded nearby), collecting rules by state and country, a life list of the 22 sharks, and one short card a day about shark teeth: history, geology, chemistry, biology, beaches. • COLLECTION LOG — Measure each tooth with your camera, pin the exact spot on your map, and watch your stats grow: species, sizes, best beaches, best days. Print specimen labels on plain paper or sticker sheets. • MY PATH & CREWS — Your route is drawn as a band on the map while you search, so you never comb the same sand twice. Form a crew and see everyone's paths, finds and latest positions on one map (creating a crew is Premium, joining is free). No signal on the beach? Hold two phones together to swap today's paths and finds. • LOOKALIKE MEMORY — Long-press a box while detecting to mark it Not a tooth; at that beach, similar shapes then show as faded boxes (never hidden). Export the memory as a file and hand it to friends. Free. • 10 LANGUAGES — Fully localized, with tide data for the U.S. (NOAA) and Japan (JMA) at meteorological-agency quality. FREE TO START Scan the beach in Close-up and Wide, check today's tide, log your finds, record your path (last 3 hunts per spot), join crews, use lookalike memory, and read the field guide, family tree, timeline, localities and daily card for free. Premium is about when and where: the 7-day pinpoint forecast with each day's best low tide, your beach's own pattern, big-tide alerts and the low-tide countdown, the bedrock card for your spots and trip destinations, the next good day for your next tooth, the morning card with a home screen widget, full path history and creating crews. Subscribe monthly or yearly, or buy it once for life.

What’s new
Version 2.7.0 · Updated September 29, 2026
• New My path button — Added in the middle of the bottom bar. Tap it and the map opens right away with your paths and your crew's paths for the day. Start and stop recording with a single button under the map. • New detection — We replaced the detection model. In the camera, boxes lag behind teeth less and linger less after you move away. • Photo analysis — Large photos are now examined down to their original pixels. Large photos show progress, and analyzing several photos at once shows an estimate of the time left. • Add to Collection from photo analysis — Photos you analyze can now go into your collection with their original capture date and place. Tides are added only when the photo records when and where it was taken. The same photo is never added twice. • Reworked tide calculations — We reworked how tide times and heights are calculated. Tides shown on photos, videos and hunt logs are recalculated from when and where they were taken (also in CSV and PDF exports). Mismatched dates in the 7-day forecast, calendar and widget are fixed. • Photos saved with boxes now keep the original photo's orientation, capture date and location.
