Hi there! We created the prototype of the world's lightest solar-powered GPS variometer for paragliding, hike-n-fly adventures and acro. It only requires sunlight to work, has a waterproof case and Bluetooth connectivity.
To run it into production, we need your vote! Please, repost our video review on Facebook: https://www.facebook.com/posts If we manage to find just 150 supporters, it will enable us to start a crowdfunding campaign, or find an investor.
And as soon as this summer you will be able to take Ungravity into the air!
