Groundrush is the friendly phone companion for the FlySight 2 GPS logger. See live telemetry, set up your ENGO 3 HUD, pull tracks off the device and replay your jump in 3D — right at the dropzone, between jumps. No laptop, no cable.

Android testing is open now, by invitation — write to [email protected] and you get added to the test. The iOS build is with Apple for review.

Roadmap

BETA

ANDROID IS IN CLOSED TESTING. THE iOS BUILD IS WITH APPLE FOR REVIEW. CONNECTING TO A FLYSIGHT AND LIVE TELEMETRY ARE CONFIRMED ON REAL HARDWARE; TRACK DOWNLOAD, HUD SETUP, GLASSES BINDING AND THE FIRMWARE UPDATE ARE BUILT BUT NOT YET FIELD-TESTED. THAT IS WHAT THE BETA IS FOR.

COMING SOON

Flash your FlySight from the browser

Update your FlySight 2 from the browser — plug it in with the USB cable and the site does the rest. Take a peek at the flasher we're building.

FAQ

What do I need to use Groundrush?
A FlySight 2 GPS logger and a phone. For the HUD features, ENGO 3 glasses with the ActiveLook firmware. Right now the app also works with tracks already on your phone.
Which platforms are supported?
Android first, iOS is on the way. The app is built with Flutter, so both share the same codebase.
What does it cost?
Groundrush is free. Everything the app does today — track library, 3D replay, jump analysis, winds aloft, HUD setup and firmware updates — stays free. Some advanced analysis may become a paid add-on later; nothing you can do today will move behind a paywall.
Does it work offline?
The track library and 3D analysis work fully offline. Winds-aloft data needs a connection, and gets cached for the day.
What track formats can I import?
.csv (FlySight format) and .gpx. Import them from any app or cloud storage, browse by day, export and share.
What is the ENGO firmware?
A custom FlySight 2 firmware with first-class ENGO 3 / ActiveLook HUD support — glide ratio and speeds right in your goggles. Groundrush is its companion app.
