A clean 1–5 daily fish rating tells you at a glance whether today is worth the trip. Under the hood, every score comes from pure astronomical maths — the same solunar tables serious bass and offshore anglers have planned trips around for nearly a century.
One glance tells you whether the moon favours the bite today — no guesswork before you load the truck.
2-hour major windows on moon transit and anti-transit, plus 1-hour minor windows on moonrise and moonset.
Every calculation runs on your device. No signal on the boat? Airplane mode at dawn? Your forecast never fails.
Solunar theory, introduced by John Alden Knight in 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.
Solunar puts that century of angling wisdom in your pocket — not as a static printed table, but as a live forecast for your exact location and date.
All feeding windows overlaid on sunrise and sunset bands, with a best-window indicator that factors in dawn and dusk overlap so you see the single best time today.
Daily fish ratings for the week ahead so you can pick the best day to get on the water — not just react to the one you're on.
Get notified before the next major feeding window opens so you're already casting when the bite turns on.
Time-of-day theming shifts from dawn slate to midday light to dusk amber, with a deep ocean-blue dark mode built for pre-dawn checks.
Free gives you everything you need for today — the daily rating, all four feeding windows, the timeline, and moon phase data including illumination percentage and days to the next full or new moon.
Solunar Fishing Pro unlocks a 30-day calendar to plan trips weeks in advance, home screen and lock screen widgets, up to 5 saved locations, and notification customisation. Pro is a monthly or annual subscription, and existing one-time Pro purchasers keep lifetime access after restoring.
Whether you chase largemouth on a quiet morning lake, run offshore for the day, or fit a quick session in around work, the question is always the same: is it worth going right now? Solunar answers it before you leave the house. The daily rating tells you if the day is strong, and the timeline shows you exactly which two-hour window to aim for — so you spend your limited time on the water when the fish are most likely to move.
Because everything is computed locally, there's nothing to fail at the worst moment. Solunar doesn't depend on a weather API that goes dark in a dead zone or a subscription server that times out at dawn. Drop into airplane mode to save battery, motor out past cell coverage, or hike into a backcountry stream — your feeding windows, moon phase, and best-time indicator travel with you and keep working. It's the difference between guessing and fishing the plan.

Yes. Every calculation runs on your device with pure astronomical maths. It works on the boat with no signal, at the lake at dawn, and in airplane mode — no server, no expiring API key, no "data unavailable".
It answers "should I fish today?" in one second using 1 to 5 fish icons, factoring in moon transit and anti-transit timing, moon phase, and lunar distance for that day.
Major windows are 2-hour peak periods centered on moon transit and anti-transit; minor windows are 1-hour periods centered on moonrise and moonset. Both appear on a 24-hour timeline over sunrise and sunset bands.
A 30-day calendar, home and lock screen widgets, up to 5 saved locations, and notification customisation. Pro is monthly or annual, and existing one-time purchasers keep lifetime access after restoring.
Yes. Your location is used only for on-device computation and is never transmitted anywhere. There are no accounts, and no internet is required for any feature.
Stop guessing and start planning around the moon. Solunar is free to download and works on every trip — even where there's no signal.
