Moon Tides is a single, quiet screen. Tide curve, moon disk, and sun arc, drawn together for the moment you're standing in. No menus to navigate, no labels to read. Numbers, glyphs, and light — the way an instrument should speak.
From the top: where the moon is, what the water is doing, where the sun stands. Each panel is a quiet instrument — no copy to skim, just shape and number. They share one background, one rhythm, one mood.
Correct terminator shadow for your latitude and the hour you're in. A soft glow that rises and falls. Stars twinkle behind. It's the night sky, drawn for the lock screen of your life.
Catmull-Rom smoothing. Day-and-night shading behind. Gold marks the highs, teal marks the lows, and a live "now" line walks the curve through the day. Heights in metres or feet — your call.
The path from rise to set, solid where the sun has already been, dashed where it's still going. A second dotted arc traces the moon's path. Compass anchors at the ends. Real time, no refresh.
Moon Tides is a reference instrument for everyday awareness. It is not a marine navigation tool. For passage planning, always consult official tide tables, charts, and the latest port authority data.
Moon Tides puts the day in front of you and gets out of the way. Four gestures move you through every screen.
Pro unlocks the deeper layers — every tide for the next 30 days, the precise windows the photographers and anglers know to wait for, and quiet notifications timed to the water and the sky. Pay once. Keep forever. Every future Pro feature included.
Every high and low for the next 30 days, with heights, sunrise, sunset and spring tides. As a list or a month at a glance. Share or print a month.

Solunar major and minor windows, computed entirely on-device. No subscription, no ping.
The exact light photographers wait for — tappable straight from the sun panel.

Anything we add to Pro lands in your app, automatically, forever.
Five small, one-time tips with names borrowed from the sea. They unlock nothing — they just keep the lights on so we can keep building.
