About this app
NaturalTimes is a smart alarm that rings with nature - the next high tide, low tide, mid tide, sunrise, sunset, or full moon - instead of an arbitrary clock time.
Built by two friends from São Miguel in the Azores whose days revolve around surfing, diving, fishing and the sea, NaturalTimes keeps you in sync with the rhythms that actually matter for time outdoors.
WHAT YOU CAN SET
• Tide alarms - High, Low, or Mid tide, computed from real harmonic data for any coastline on Earth.
• Sun alarms - sunrise or sunset, calculated precisely on your device.
• Moon phase alarms - full moon, new moon, first or third quarter.
• A before/after offset - e.g. “ring 1 hour before low tide”.
MADE FOR TIME OUTDOORS
Whether you surf, dive, fish, sail, forage or just love a good sunrise, pick the exact natural window you care about and let NaturalTimes wake you for it - even offline once it’s set.
SMART, RESPECTFUL ALARMS
• “Daylight only” - never ring outside your chosen daylight window (with an adjustable grace margin).
• “Do not disturb during working hours” for tide alarms.
• Choose the days of the week, name your alarm, set vibration.
• Tap a spot on the map or search a place - your surf break, dive site, beach or trailhead anywhere in the world.
PRIVACY BY DESIGN
No accounts, no sign-in, no ads. Sun and moon times are computed entirely on your device. Only tide alarms send the chosen coordinates to our own server to compute the tides - nothing is sold or shared.
FREE & PREMIUM
Free: up to 3 alarms (one active at a time) and 15 locations per month.
Premium (yearly subscription): unlimited alarms, all active at once, unlimited locations, and custom ringtones.
Tide, sun and moon times are estimates from mathematical models - always use official sources and your own judgement for navigation or safety-critical activity.
Sync with the rhythm of nature.
