AltiX Skydiving vs Groundrush Skydiving

AltiX brings skydiving planning, jump logging, and equipment tools together on iPhone and Apple Watch. APPLE WATCH ALTIMETER AND JUMP LOGGER • View a clear altitude display using fused, barometric, or demo mode. • Automatically calibrate on the ground and detect takeoff, freefall, canopy flight, and landing. • Record altitude samples and a phase-tagged GPS route. • Save an original point and see live distance and direction back to it. REVIEW EVERY JUMP ON IPHONE Completed watch logs sync to the paired iPhone for detailed review. Explore the altitude profile, summary data, and GPS track, with different colors for takeoff, freefall, and canopy flight. Export a raw JSON copy through the system share sheet when you want to analyze or archive your data elsewhere. WIND-AWARE MAP PLANNING • Landing Pattern Assistant: Generate wind-adjusted standard patterns for student, experienced, and expert canopy profiles, or design a custom swoop route with draggable waypoints. • Exit Spot: Estimate an exit range using wind aloft, freefall drift, deployment altitude, and canopy performance. • Cutaway Finder: Estimate a detached canopy’s probable path and landing area using cutaway altitude, fall rate, and forecast or historical wind data. • Automatic or manual wind profiles let you plan with online data or enter local observations yourself. ESSENTIAL SKYDIVING TOOLS • Wingload Calculator with linked weight, canopy size, and wing-loading values. • Repack Reminders for multiple rigs, configurable intervals, advance notice, and local notifications. • Feet or meters for altitude, and kilometers or miles for distance. • English and Simplified Chinese interface options. FREE AND PRO ACCESS The free plan includes Standard Landing Pattern Assistance, the Wingload Calculator, and Repack Reminders. AltiX Pro unlocks the complete iPhone and Apple Watch feature set. Monthly and annual subscription options are available. IMPORTANT SAFETY NOTICE AltiX is a planning and logging aid. It is not a certified altimeter, navigation instrument, or life-safety device. Sensor readings, GPS, wind forecasts, calculations, batteries, and software can fail, lag, or be inaccurate. Always use certified equipment, current local observations, qualified instruction, and established drop-zone procedures.

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. NOT AFFILIATED Groundrush is an independent project. It is not made by, endorsed by or affiliated with FlySight or ActiveLook.
