Solunar: Best Fishing Times

Know exactly when the fish are biting. Solunar Fishing Times uses proven solunar theory to predict major and minor feeding windows based on the moon's position -- no internet required, no weather API, no subscription. A clean 1-5 daily fish rating tells you at a glance whether today is worth the trip.

Every calculation runs on your device using pure astronomical maths. That means it works on the boat with no signal, at the lake at dawn, in airplane mode, on every trip. No server, no API key that expires, no "data unavailable" when you're finally at the water.

WHY SOLUNAR?

Solunar theory (John Alden Knight, 1926) is the most widely used framework for predicting peak fish activity. Fish feed most aggressively when the moon is directly overhead (transit) or underfoot (anti-transit). Moon phase (full and new moons are best) and lunar distance (perigee means stronger pull) further refine the prediction. Serious anglers have planned trips around solunar tables for a century.

FEATURES

- Today's solunar rating: 1-5 fish icons, the answer to "should I fish today?" in one second
- Major feeding windows: 2-hour periods centered on moon transit and anti-transit -- the peak bite times
- Minor feeding windows: 1-hour periods centered on moonrise and moonset
- 24-hour visual timeline: all feeding windows overlaid on sunrise and sunset bands
- Best window indicator: the single best fishing time today, factoring in dawn and dusk overlap
- Moon phase display: current phase name, illumination percentage, days to next full or new moon
- 7-day calendar: daily fish ratings so you can pick the best day this week
- Notifications: get alerted before the next major feeding window so you can be on the water
- Coastal design: time-of-day theming shifts from dawn slate to midday light to dusk amber
- Dark mode: deep ocean blue palette optimised for pre-dawn checks

NO WEATHER API -- BY DESIGN

Most fishing forecast apps depend on a weather API for barometric pressure or temperature data. When y
