Yarely is a complete sailing companion across iPhone, iPad, Apple Watch
and the web: log passages underway, feel alarms on your wrist, and plan routes from any
screen — every change synced privately with your Apple ID.

THE PROBLEM
Passage planning is still scattered across the boat.
Every skipper knows the ritual: the almanac, three weather apps, a chart,
and a damp notebook — none of them talking to each other, none of it with you when
you're away from the boat.
📖
Tides live in a book
High water is in the almanac at the nav station. Your draft calculation happens on
a scrap of paper — if it happens at all.
🌦
Weather lives in apps
Wind in one app, radar in another, none of it overlaid on the chart you're actually
planning on.
📝
Knowledge lives on paper
The marina's VHF channel, the shallow patch by the entrance, which pontoon to call —
pilotage wisdom that never survives the season.
HOW IT WORKS
One crew: iPhone, iPad, Watch and the web.
Work on whichever screen is to hand. Every change flows to all the others.
1
Plan
Plot routes and drop waypoints right here in the browser — check tides, depths and
marinas from the comfort of home, ready before you step aboard.
PLAN ON ANY SCREEN
2
Sync
Sign in once with your Apple ID. Waypoints, routes, trips and position sync
both ways and privately — no accounts to invent, nothing shared with anyone.
PRIVATE, TWO-WAY SYNC
3
Sail
Everything is waiting on board: the iPhone and iPad log your track, speed and trips;
the Watch puts SOG, steer-to arrows, anchor watch and a man-overboard button on your wrist.
IPHONE · IPAD · APPLE WATCH
THE PLATFORM
Everything a passage needs, on one chart.
🗺
Live chartplotter
Your vessel's position, course and 48-hour track on a proper nautical chart — on iPhone,
iPad and right here in the browser, with waypoints and routes synced between them all.
⛵
Real sea charts
Switch the map to real nautical raster charts — seamarks, lights and buoyage from
OpenSeaMap. Streamed on the web, downloadable by region on iPhone and iPad for
offline plotting with no signal at all.
Ships around you as classic plotter targets — green triangles on course, name, speed
and heading a tap away. Community-run open AIS via your free aisstream.io key.
AWARENESS ONLY — NEVER FOR COLLISION AVOIDANCE
🌊
Real tidal curves
Interpolated tide curves with high/low water times from the nearest official station,
worldwide. Search any port, marina, tide station or lat/lon and scrub the curve with
a finger to read the height at any moment.
📏
Draft-aware depth windows
Set your draft once. Tap any berth or anchorage and see exactly when there's enough water
under the keel — charted depth plus the tide, hour by hour.
DECISION SUPPORT — ALWAYS VERIFY WITH OFFICIAL CHARTS
📍
Tap-anywhere spot card
Touch any patch of water for the full picture: position, range and bearing from the
boat, tide now and next, charted depth and local wind — then save it as a waypoint
with one more tap.
💨
Weather on the chart
Matching layer toggles on every screen: live wind fields with gusts, rain radar,
seamarks, depth contours, tide stations and marinas — the picture you actually plan
a passage with.
🌤
10-day marine forecast
Interactive forecast charts you can scrub: wind with its gust envelope, temperature,
rain and pressure trend — for your position or anywhere you search.
⚓️
Anchor watch that wakes you
Arm it from phone, watch or wrist. If the boat drags outside your swing circle, the alarm
reaches a locked phone — and taps you awake on your Apple Watch.
🌙
Red night mode
One switch turns the whole app — charts, sheets and all — into shades of red that
preserve night vision at the helm, the way astronomy apps do it.
🧭
16K+ marinas
A searchable worldwide marina catalogue with facilities, VHF and contacts, your own
pilotage notes synced between web and boat, and one-tap "set as destination".
🧾
Routes & GPX
Plot routes on any screen, drag waypoints to refine them, and everything syncs both
ways. GPX import and export keeps your data portable to any other navigation kit.
ON DECK
The iPad becomes the chart table.
One layout for the helm: instruments on the left, layers on the right,
the chart everywhere else.
Charts, layers and instruments
Real OpenSeaMap charts with buoyage and lights, live wind with gusts, tide stations
and AIS — flicked on and off from the layer rail while SOG, tide and ETA hold the
left column. Downloaded regions keep working offshore with no signal at all.
Red night mode
One tap on the NIGHT toggle and the whole app — chart, instruments, sheets and all —
renders in shades of red with the chart inverted dark, the way astronomy apps protect
your eyes. Night vision stays intact for the watch; daylight colours return with a tap.
A WORKED EXAMPLE
"Can I get into the marina at six o'clock — or do I wait for the tide?"
That's the question that actually decides a passage. Yarely answers it in one
card: the charted depth at the berth, your draft and safety margin, and the tide —
combined into the hours you can safely enter.
Tap "set as destination" and the marina drops into your routes and the app's
passage plan on iPhone and iPad — ETA, daylight check and tide on arrival — with your own pilotage
notes attached.

Speed over ground from the watch's own GPS, a steer-to arrow for the active waypoint,
anchor watch with haptic drag alarms, and a man-overboard button you can hit with a
gloved fist.
TRUST
Private by design. Honest by default.
Sign in with Apple
No passwords to invent, no email lists. Your Apple ID is the account, and Apple
never shares more than you allow.
Yours to delete
One tap in the app permanently deletes your account and every synced waypoint, trip
and position from our servers.
Official sources
Tides from Open Waters — harmonic predictions from official station networks
(TICON‑4, NOAA) worldwide. Depths from EMODnet surveys. Weather from
national forecast models. Attributed, always.
Honest data
If real data isn't available — no tide station in range, say — we show nothing
rather than a guess. Anything indicative is badged as such, in amber, on the data
itself — never buried in small print.
COMMUNITY
Ask a question. Read the log.
A public board where skippers ask questions, help each other, and the
developer posts release notes — no account needed to browse.
Questions, feature ideas, marina corrections, or just where you sailed
this weekend — messages land straight with the skipper who builds Yarely.
