Calendar
A 0–4 bite-activity score from the Moon phase and how periods line up with dawn and dusk.
Major (~2 h) at lunar culminations, minor (~1 h) at moonrise and moonset — the best activity windows.
Computed from astronomical primitives: phase, moonrise/moonset, sunrise and sunset.
Switch quarry — fish or game; the best time for your pursuit.
In PRO — alerts for the best periods on high-rated days.
The forecast is computed on the device from your coordinates — no internet needed on the water.

FAQ
How is the bite computed?
By solunar theory: the Moon phase and how major/minor periods (lunar culminations and moonrise/moonset) line up with dawn and dusk. A guide, not a guarantee.
Does it work offline?
Yes, the whole forecast is computed offline from your coordinates.
Is it good for hunting?
Yes — switch quarry to game and activity periods are computed the same way.
How much is it?
Ratings and periods are free. Best-window reminders are in PRO.
