The science
How the windows are found
Solunar theory says fish and game feed more when the moon is overhead, underfoot, rising or setting — and even more when that lines up with dawn or dusk. Solunar computes these moments from astronomy for your exact position.
Centered on the moon passing overhead or underfoot.
Centered on moonrise and moonset.
A window that overlaps sunrise or sunset. Prime time.
Moon phase, perigee and sun stacks scored into one number.

Questions
Does it need an internet connection?+
No. Every calculation runs on your phone from your GPS position and astronomy formulas, so it works in the backcountry with zero bars.
What happens to my location?+
It is used on the device to compute sun and moon times and never leaves it. There is no account and no server storing your data.
Is solunar theory proven?+
It's a time-honored rule of thumb that many hunters and anglers swear by. Weather, pressure and season matter too — use the windows to plan, then trust what you see outside.
Which devices are supported?+
iPhone and Android phones. Widgets are available on both; the Live Activity countdown is on iPhone.
The moon is on your side. Go.
