Sync with
the rhythm of nature.
NaturalTimes rings when nature does — the next high tide, first light, a full moon, or the exact combination you wait all season for.
The ocean doesn't check your calendar.
Swell peaks at first light. Fish bite on the moving tide. The reef only shows at low water. You already know the window — NaturalTimes makes sure you're awake for it.
Pick a spot, pick a natural event, add an offset. No tide math before bed, no 4 a.m. guesswork. Alarms keep working offline once they're set — and everything that can stay on your phone, stays on your phone.
Alarms bound to nature's cycles
Tides
The next high or low, for any coastline on Earth — minutes or hours before it turns.
Sun
Sunrise and sunset computed for your exact break. Not your city — your break.
Moon
Fire on full, new or any phase — at a fixed hour, or relative to the sun.
Combinations
High tide at sunrise. Low tide on a full moon. Stack the conditions — it does the math.
Daylight rules
Quiet hours and working windows — nothing rings at 3 a.m. unless you want it to.
Private by design
No account. No ads. No tracking. Only tide lookups ever leave your phone.
Three taps to the perfect window
Drop a pin
Your break, dive site, trailhead or fishing spot — anywhere on Earth.
Pick the moment
Tide, sun or moon — or a combination — with a before/after offset.
Let go
It rings at exactly the right window — even offline once it's set.
Made on an island in the middle of the Atlantic.
NaturalTimes is built by two friends from São Miguel — the largest island of the Azores, where ocean, sky and volcano meet. Our days revolve around surfing, diving, fishing and sailing, and we wanted alarms that follow the water, not the office.
No ads. No data harvesting. The price barely covers the servers. If it's useful, pass it on — in the Azores and anywhere people still read the sea and the sky.
