Do you know XCTracey?
Are you hiking to fly, carrying minimalised gear, and do you own a Garmin Smartwatch?
Then you might want to check out XCTracey – a ConnectIQ app turning your vivoactive, ForeRunner or Fenix with pressure sensor into an autonomous wrist vario. Have a look at the main menu on top of the page!
XCTracey features calibrated altitude, speed, L/D, vario, wind and much, much more. The best: it’s completely free (though I appreciate any PayPal donation).
