About us
We are Marta, Sergio and Javier, competition glider enthusiasts. We have been largely involved in F5J FAI altimeter contests since the formula was created.
We are proud to say that we created GliderLink, the world's first QR-code time-keeping application and also the first Internet-based one, routinely used in Spain — running since around 2011. The others just followed us.
We have been helping Glider CG launch the successful GliderThrow.
We are also deeply engaged in organizational matters, and since 2009 our group organizes the F5J Masters. As a result, we built a little gadget called GliderTimer (original), a cigarette-pack-sized device that can manage all the public address and sound tracks at an F5J contest — we've been using it for three years now. You only need a portable loudspeaker system and GliderTimer (original) to run your contest: no laptop needed in the field, whether for classifications (GliderLink) or soundtracks (GliderTimer original).
But if you've been down this road before, you'll agree that one of the hardest things about organizing an F5J contest is having an acceptable cast of timekeepers. After long discussions and many hard hours of work, we ended up with GliderKeeper.
GliderKeeper comes as a help to pilots in training sessions and small training events or leagues, where you can easily imagine all the pilots in the field flying together in the same group.
We envisage that many contest organizers will see this device as a tool that can be very useful for organizing their competition with limited human support.
GliderKeeper, for the moment — let's see how the future evolves — does not completely replace timekeepers, but it will help a great deal when only a limited number of timekeepers are available.
GliderKeeper is young, and there will be software updates, corrections and new features added to this new environment.
We'd love to hear from you at support@gliderkeeper.com with your opinions, suggestions or complaints…
