Live map & traffic
Public ADS-B traffic, airports, navaids, charts and METAR/TAF. Your own aircraft appears when the bridge is connected.
Flight simulation companion
Every flight.
Properly recorded.
A lightweight map, career logbook, replay, landing analysis, briefing and route planner for X-Plane and Microsoft Flight Simulator — with secure access from your iPhone.

Connectivity, aircraft and position come from the bridge. If it is offline, Stratos says so instead of inventing data.
Built for the way sim pilots actually fly
Recorded data first. Estimates are labelled. Nothing is uploaded unless you pair a phone.
◈
Career logbook
Hours, distance, airports, aircraft, routes and records, calculated once from your real flights without double counting.
↺
Flight replay
Scrub through the recorded track with a moving aircraft, altitude/speed profiles and clear markers for recorded versus interpolated values.
↘
Landing analytics
Touchdown rate, ground speed, runway and distance from the threshold where the data supports it — with per-aircraft thresholds.
☁
Briefing & routes
Build a route, validate waypoints, import/export PLN, FMS and GPX, then brief weather with source and freshness.
▤
Phone live view
A secure PWA reads telemetry through an outbound relay. No inbound port, no command channel, no App Store account.
Install Stratos
The website, Windows app and iPhone app use the same application files, so features stay consistent.
Desktop app
- Download
Stratos-Setup.exe. - Run the installer. SmartScreen may warn because the build is not code-signed — choose More info → Run anyway.
- Launch Stratos. The simulator bridge starts with the app.
All releases: GitHub Releases ↗
Add to Home Screen
- Open Stratos in Safari.
- Tap Share, then Add to Home Screen.
- Open the icon and connect it to your PC in Pilot → Settings → Phone access.
Needs HTTPS for installation. Live telemetry needs the relay and the desktop bridge running.
Use it now
- Open the tracker — no install.
- Browse public traffic and airports.
- Open Pilot for the logbook, replay, landings and flight planning.
Your logbook is stored locally in the browser or the desktop app.
Simulator setup
X-Plane 11/12: Settings → Data Output, enable rows 3, 17 and 20 to UDP port 49003 on the PC running the bridge. MSFS 2020/2024: start a flight; install the optional SimConnect Python package once if available. The bridge reports exactly which source is connected and when telemetry goes stale.
Phone relay and privacy
The desktop bridge pushes snapshots outbound to a relay you host. The phone pairs with a short-lived code and receives a separate read token. The relay has no command channel to the PC, tokens are hashed at rest, and the bridge is never exposed to the internet. Pairing and revocation are in Pilot → Settings.
