Telltale
Sailing weather, racing & logs
Free · Designed for iPad. Not verified for macOS.
Plan a route with sail and motor times from your boat's polar and the forecast. Check every forecast model against live wind, and record every sail.
Sailing weather, racing and logs in one app. Check the wind before you go, plan the route, record every sail, and see how it went: tacks, polars, the fleet and the race.
WIND, TIDE AND CURRENT
Live readings from nearby stations and buoys on a map, with every forecast model side by side. The model closest to recent readings is marked, so you know which one to lean on today. Tidal currents through the passes, tide heights, and an hour-by-hour table for any spot.
PLAN AND FOLLOW A ROUTE
Plan a route on the map and see how long it takes under sail, from your boat's polar and the forecast, or under motor. The tacks are drawn in colour, and the route steers around land and shallows. Saved routes are shared with your boat and crew and work offline, and Onboard follows one with off-course cues.
RECORD EVERY SAIL
Record with your iPhone's GPS, or connect to your boat's instruments over its Wi-Fi for wind, boat speed and depth. A laptop or a small boat computer aboard can record every sail on its own.
SEE HOW IT WENT
Each sail on the chart and the log strip: speed, wind, tacks and gybes, against your boat's polar. Telltale points out what stood out, and your season adds up sail by sail.
RACING
Find races and regattas near you with entries, courses and notices. After the gun, replay the race with the fleet around you from AIS, and see where you gained and lost.
ON YOUR WRIST
Apple Watch shows live wind, boat speed and depth, runs your start timer, and records your heart rate beside the wind.
YOUR SAILS STAY YOURS
Sessions are private by default, your home berth is hidden from anyone outside your crew, and your heart rate stays private unless you share it. Download recordings as GPX, FIT or CSV.
A free account supports two boats. Boat instrument readings need compatible equipment. Telltale is not a navigation aid.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Plan a route on the map: times under sail from your boat's polar and the forecast, and under motor, with the tacks in colour, the forecast spread and a speed plot. It routes around land and shallows. Saved routes reach your boat and crew and work offline, and Onboard follows one with off-course cues and arrival.
Onboard is now cards you swipe: instruments, timer, route and recorded. Stopping a sail asks for a name, then Keep or Discard. The start timer resets while paused, a boat's recorders share one device list, the map pans and follows the boat more smoothly, and boat icons have a straight stern. And many fixes.
