TrimSmart fetches wind data from the nearest weather station.
Since this may not always match on-water conditions, you can manually input wind strength for better accuracy.
The app will then recommend optimized sail settings.
🧭 Help & Tuning Guide
Each setting includes a “Help” link that redirects to onedesignsails.com/tuning, where you’ll find detailed tuning guidance.
You can also:

Customize and save factory settings
