Flood-Cast is a coastal flood early-warning app for Florida's Gulf coast — created after Hurricane Helene pushed record surge into homes along the coast, from the barrier islands to Tampa Bay. Instead of burying you in raw weather data, Flood-Cast watches the specific conditions that drive coastal flooding and tells you, in plain language, how worried to be right now. THE 4 FLOOD CONDITIONS Flood-Cast continuously checks the four factors that line up during the worst coastal floods: • Spring tide — a full or new moon, when tides run highest • King tide — a predicted high tide above the king-tide line • Hurricane on a parallel track — a storm running along the coast • Eye 40–75 miles offshore — close enough for the outer bands to push water inland As these stack up, your risk ring climbs from Minimal toward Flood Now — so you can watch the conditions building instead of being caught off guard. RECALIBRATED AGAINST HELENE Helene drove more than six feet of surge with its eye far offshore — a combination simple rules miss. Flood-Cast layers storm-surge, storm-size, and distance escalators on top of the base gate, so a large, distant, surge-driving storm still raises the alarm. WHAT YOU SEE • A friendly risk ring with a plain-language summary • The live 4-condition checklist, so you can watch conditions stack up • A tide curve with the king-tide line, highs, lows, and a "now" marker • A hurricane tracker showing the eye's distance, bearing, and the danger band • The moon drawn in its current phase • A 12-hour AI outlook that reads the trend and explains what's coming LIVE DATA • Tides from NOAA Tides & Currents (your nearest Florida station) • Active storms from the National Hurricane Center • Moon phase computed on your device — no network needed Flood-Cast won't cry wolf. A full Flood Now alert only fires when the conditions truly line up; the rest of the time it quietly shows you the coast is calm. Built for residents, renters, and anyone who loves the Gulf coast and wants a head start before the water rises. A 3-day free trial unlocks the full app. Continuous monitoring and alerts are available by subscription.

Verdict
The clearest difference is ads: Flood at none against Tide Buoy's shown. Flood also leads on update cadence (daily vs weekly). Tide Buoy's advantage is ratings volume (8 vs 1). On price, rating, review sentiment and in-app purchases there is nothing between them.
