Tidewatch

A beach-day safety companion that pings your phone when a GPS-tagged great white enters a custom radius of your chosen swimming spot and overlays historical sightings for that coastline.

Target user

East Coast US and Canadian Atlantic beach vacationers planning a swim day with family or kids

Features
  • Live proximity alerts from OCEARCH and Atlantic White Shark Conservancy tag pings
  • Custom radius (0.5–5 miles) and quiet-hours scheduling
  • Historical sighting heatmap for any chosen beach, weighted by day-of-year
  • Lifeguard flag status and rip-current advisory pulled from local beach authorities
Why now

The 'Contender' tracking story just drove 100+ trending searches in Canada alone and reminded coastal travelers that a giant tagged shark is actively approaching their vacation beach; most generic beach apps don't surface marine wildlife at all.

Demand

Contender story widely covered (CTV, Yahoo, Fox Weather, OCEARCH) and multiple tagged GW pings off Outer Banks/NL drive seasonal search spikes; NPS officially recommends Sharktivity confirming real user pull.Largest male great white shark recorded in Atlantic resurfaces off Canadian coast2 great white sharks tracked off North Carolina's Outer Banks this week

Whitespace

Direct, entrenched competitor Sharktivity (by Atlantic White Shark Conservancy) already offers GPS-tagged GW sightings, push beach alerts, and is officially integrated with Cape Cod NPS/Mass DMF; OCEARCH Global Shark Tracker covers the same data feed.Sharktivity White Shark Tracking App — AWSCOCEARCH Shark Tracker

Monetization
4/10

Sharktivity Pro (launched Oct 2024) validates a paid tier but gates only widgets/early-access — core alerts stay free, suggesting low WTP; seasonal, vacation-only usage caps subscription LTV.Introducing Sharktivity Pro - Instagram announcementSharktivity on the App Store

Longevity
5/10

Great white range expanding northward into Canadian Atlantic (Contender in Gulf of St. Lawrence) is a multi-year climate-driven tailwind; OCEARCH's tagging program is sustained by long-term research funding.Largest great white shark recorded in Atlantic, in Canada

Feasibility
5/10

Wrapper/aggregator is technically trivial, but value depends on third-party data (OCEARCH ping feed, Sharktivity, local sightings) — no proprietary data source and Sharktivity/OCEARCH already own the authoritative feeds.Track Sharks With Us | OCEARCH Shark Tracker
