Groundrush

Groundrush is the free phone companion for the FlySight 2 GPS logger. Set up
your ENGO 3 heads-up display, pull a jump off the logger over Bluetooth and
look at it — standing in the packing area, between jumps.

WHAT IT DOES

• ENGO 3 HUD setup — choose what the glasses show and where, how often they
refresh, and bind the FlySight to your own pair of glasses. The logger drives
the display directly; the phone is not part of the link in flight.
• Track download — pull recorded jumps off the FlySight 2 over Bluetooth.
• Track library — import .csv and .gpx files, browse them by day, export and
share. The library lives on your phone and works offline.
• Jump analysis — exit altitude, freefall time, speeds and glide ratio, with
automatic detection of the flown segment, and charts you can read at any
instant of the jump.
• Map View — the route drawn over a satellite or road map, coloured by speed,
with exit and landing marked.
• Winds aloft — wind by altitude, so the charts can also show what you flew
with the wind taken out.
• Firmware updates over the air for the ENGO HUD firmware.

GROUNDRUSH CLOUD (OPTIONAL)

• Sign in with Apple or Google. There is no Groundrush password.
• Upload a track and it is kept privately in the cloud; open it in a browser
at groundrush.io.
• Make a jump public when you want to share it. A public page shows your
username and photo, wingsuit, dropzone, the date and time, the shape of the
path, the wind and the charts — never the GPS coordinates or the original
file.
• Auto Upload — when it is on, every detected jump goes to the cloud right
after the download from the FlySight.
• Wingsuit and dropzone on each track, picked from shared lists.
• Delete your account from the app at any time.

WHAT IT DOES NOT DO

The app works fully without an account. No advertising. No analytics, and no
tracking of any kind. Without an account your tracks are files on your phone
and nothing is uploaded. What does leave the device: a jump's coordinates and
date, sent to a public weather service to look up the wind; map imagery
requested from Google when you open a map; and a firmware check with GitHub.
With an account, the app also sends to Groundrush's own servers the track files
you upload, the profile you enter and the photo you choose. All of it is
described in full in the privacy policy.

Groundrush is free. Everything listed above stays free.
