--- FISHING SCORE ---
A real-time 0–100 score rates current conditions based on solunar periods, tides, moon phase, season, and light. Tap any hour on the 24-hour bar chart to see predicted scores and plan your morning before you go to sleep.
--- SOLUNAR TABLES ---
Major and minor feeding periods calculated for your exact location. See which period is active right now, countdowns to the next window, and all four daily periods at a glance.
--- TIDE CHARTS ---
Harmonic tide calculations — fully offline. Visual chart with rising/falling indicator, next high and next low times. No internet, no API, no surprises.
--- PRIME FISHING WINDOWS ---
Blue hour and golden hour tracked for morning and evening. Fish feed aggressively in low light, FishWhistle shows exactly when those windows open and close, with live active indicators.
--- MOON & SUN EVENTS ---
Moonrise, moonset, sunrise, sunset. Full moon and new moon countdowns. Moon age. Last full moon. Everything you need to understand where you are in the lunar cycle.
--- UV INDEX & SHADOW LENGTH ---
Know when the sun is high enough to push fish deep, and when falling shadows bring them back to the shallows.
--- DATE BROWSER ---
Plan future trips with full confidence. Browse any upcoming date and see its complete solunar table, tide chart, fishing score, and all conditions. Scout next weekend before you leave the couch.
--- SEASON COUNTDOWN ---
Solstice and equinox countdowns. Fish behavior shifts with the seasons, know exactly how far you are from the next one.

Every calculation happens on-device. No internet connection required, no account, no sign-in. FishWhistle works in the middle of nowhere, because that's where the fish are.
