Solunar: Best Fishing Times

WHAT IS SOLUNAR THEORY?

Solunar theory (John Alden Knight, 1926) is the most trusted method anglers use to predict peak feeding activity. Fish bite most aggressively when the moon is directly overhead (transit) or underfoot (anti-transit). Moon phase and lunar distance further refine each day's score. Serious bass and offshore anglers have planned trips around solunar tables for a century.

Works offline — always

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 finally reach the water. Unlike weather-dependent apps, your solunar forecast never fails.
