About this app
Know when to cast. Castline turns NOAA tides, barometric pressure, solunar
periods and water temperature into one simple fishing score for your spot —
so you spend less time guessing and more time fishing.
WHY ANGLERS KEEP CASTLINE
• One honest number — a 0–100 fishing score for today, hour by hour, with the
best bite window highlighted
• Every score explained — tap any score to see exactly how tide phase,
pressure, solunar and water temp contributed. No black box.
• Tides & bite windows — high and low tides with major and minor bite windows
on one clean chart, plus the moon for the whole week
• 7-day outlook — see the best days coming and plan the weekend early
• Built-in spots — piers, beaches, reefs and ramps across the US coast, or let
Castline find the closest one to you
• Any style — surf, pier, jetty, kayak, boat or shore fishing
TIDE CLUB — WATERSIDE, NOT ON THE MAP
• Share a quick report from the water — "bites picked up on the incoming" —
tagged to the water area, never to your exact spot
• Your logbook and honey holes stay on this device unless you choose to share
• Crew up with friends, plan a cast together and see who's in
• No ads in the feed. Coordinates can't be posted — the app won't let you.
PRIVACY, NOT PROMISES
• No account needed to start — open the app and fish
• Your location is only used if you choose it, and your saved spots stay on
this device only
• Built on public data: NOAA tides, Open-Meteo weather and local solunar math
