Be out there at the right hour.
Moonline sends you an alert when the moon lines up with sunrise or sunset at your spot. You'll know days ahead instead of guessing.

The best hours, worked out for your spot
Solunar periods are the hours when the moon is overhead, underfoot, rising or setting. Solunar theory holds that fish and game move most during those hours, and the effect is strongest when a period lands on sunrise or sunset.
Moonline finds those windows for every spot you save, then:
- 1Rates each day Best, Good or Fair.
- 2Tells you when each window opens and peaks, in your spot's local time.
- 3Reminds you in time to plan the trip, pack the truck and get set up.
Alerts that fit how you plan
- A week out: Best days only, with time to plan the trip.
- The day before: a 7 PM heads-up.
- Day of: 1, 2 or 4 hours before the window opens.
- Your call: Best days only, or Good and Best.
They arrive with no signal
Alerts are scheduled on your phone, so they still go off at the lake, in the stand or in the blind. No server, and no bars needed.

Built for anglers and hunters
Save the lake, river, marsh, stand or blind you actually go to. Bass, redfish, speckled trout, whitetail, waterfowl or turkey: Moonline works from the sun and the moon at your exact location.
For hunting spots, windows are trimmed to legal shooting light, so a window that's mostly after dark can't rate Best.
Keep a trip log, and see if it works for you
Answer "How did it go?" after each trip. After five trips, Moonline shows you how your Best days compare to the rest.
Accurate by design
Sun and moon times are calculated on your phone and validated against U.S. Naval Observatory data, to within two minutes across a full year of test locations.
Legal shooting light is an estimate. Always check your state's regulations.
Try it before you install
Open a Moonline link, or scan a Moonline code, and the App Clip shows the next window and this week's Good and Best days for that spot or where you're standing. Nothing to download first.

Questions
Do I need an account?
No. There's no sign-up. Your spots stay on your phone.
Does it work offline?
Yes. Sun and moon times are calculated on the phone, and alerts are scheduled on it. Tides and weather need a connection to refresh.
Does it work outside the U.S.?
Sun and moon times and alerts work anywhere. Tide predictions come from NOAA and cover U.S. coastal stations.

iPhone with iOS 17 or later.
