What's New in Telltale

1.9.9

November 7, 2026

Vakaros Atlas 2, live (Preview): connect your Atlas 2 from the Record tab and record heading, heel, trim and speed live, with wind, depth and position from the unit. Open Vakaros .vkx files (and CSV logs) straight into Telltale from the share sheet or Files. Routes can now be worked out on the phone itself, so routing keeps going offline and in Racing mode.

Weather and racing intelligence all in one place!

This app combines everything I’ve been dreaming of for years in one easy to use package.
Now I have confidence in how forecasts will evolve throughout the day given the live conditions.
The onboard features including Apple Watch and Garmin support are great.
We’ve found the performance analysis tools to fun and useful for sailing faster!
It’s so cool to be able to share our position/instruments along with the AIS data covering our rivals LIVE as we’re sailing so our friends and family can follow along in real time.

FAQ

What sailing data does Telltale provide?

Telltale offers live wind, tide, and current readings from nearby stations and buoys, alongside forecast models. It also provides tidal currents through passes and tide heights with hourly tables for any location.

Can Telltale help me plan my sailing routes?

Yes, you can plan a route on the map and see estimated travel times under sail or motor, considering your boat's polar and the forecast. Routes can steer around land and shallows, and saved routes work offline and can be shared with your crew.

How does Telltale record my sails?

You can record your sails using your iPhone's GPS or by connecting to your boat's instruments over Wi-Fi for wind, boat speed, and depth. A dedicated boat computer can also record sails independently.

What information is available after a sail or race with Telltale?

After each sail, you can view it on the chart and log strip, showing speed, wind, tacks, and gybes against your boat's polar. For races, you can replay with the fleet from AIS to see where you gained or lost positions.

Does Telltale work on Apple Watch?

Yes, the Apple Watch version shows live wind, boat speed, and depth. It also runs your start timer and can record your heart rate alongside wind data during sails.

Is my sailing data private with Telltale?

Sessions are private by default, with your home berth hidden from anyone outside your crew. Your heart rate also remains private unless you choose to share it. Recordings can be downloaded as GPX, FIT, or CSV files.

How many boats can I track with a free Telltale account?

A free account with Telltale supports tracking up to two boats. If you need to track more, you would need to consider alternative solutions or check for potential future premium features.

Does Telltale have ads?

No, Telltale does not contain advertisements. The app is free to use and does not display any ads to its users.
