About Cobalt

Built by sim pilots. For the flight you are already flying.

Cobalt Simulations is an independent studio. We make the companion app your simulator never shipped with: the flight on the phone already in your pocket, wired to MSFS or X-Plane through one small Bridge.

Why it exists

Long-haul is the hobby. Sitting at the desk for six hours is not.

A long flight is the best part of the sim. It is also six hours of one chair, one monitor, and a room you cannot leave. We did not want a second simulator. We wanted the flight to come with us.

The phone was already in our pocket. It knew how to show a map, buzz at the right moment, and live on a Lock Screen. It only needed to know about the aircraft. So we built the Bridge, and Cobalt followed.

What it is

A companion. Not a simulator.

Cobalt does not fly anything. It follows the aircraft you already fly, in the sim you already own.

Follows your flight

Live map, Lock Screen Live Activities, airport briefing, and a logbook that writes itself from real telemetry.

Reaches back into the sim

With Peak, autopilot, lights, engines, and cameras answer from the phone. Over Wi-Fi at home, over cellular with Relay.

One small Bridge

A free app for the sim PC. Windows or Mac. It finds MSFS or X-Plane on its own and talks to the phone on your Wi-Fi.

Principles

What we hold to.

Six lines. They decide what ships and what does not.

01 Free to fly.

The map, the Lock Screen, the briefing, and the logbook cost nothing. Nothing on the free plan is hidden, limited by a timer, or interrupted.

02 Peak goes deeper.

Peak is for pilots who want control and history: remote systems, Relay over cellular, ATC messaging, reports and playback, and the Bridge on three PCs. One clear line, and you can read every item on it.

03 Honest by design.

Hours, landings, and grades come from telemetry. The Bridge keeps recording if the phone drops. A sim-rate badge marks what was flown at speed. If the logbook can lie, it is not Cobalt.

04 Private by default.

Your flights live in your account. We do not sell personal information, and we do not collect more than the app shows you. The privacy policy is short enough to read.

05 Independent.

Cobalt Simulations is not affiliated with, endorsed by, or partnered with VATSIM, IVAO, Microsoft, Asobo Studio, or Laminar Research. We build for their pilots, on our own account, and we follow the same rules every pilot does.

06 Native, or not at all.

Cobalt is built for iPhone and iPad first: Live Activities, Dynamic Island, widgets, Apple Watch. It should feel like it came with the phone.

The story

From a long flight to the App Store.

No funding round, no launch party. A problem on a desk and a phone in a pocket.

  1. The idea
    A long leg, and nothing on the phone about it.

    The flight was hours from top of descent. The phone on the desk knew the weather, the news, and the score. It knew nothing about the aircraft. The question was simple. Why not?

  2. Cobalt Bridge
    The small app on the sim PC.

    The first piece had to find the sim on its own, speak to both MSFS and X-Plane, and never ask for a pairing code. It still does exactly that, and it is still free.

  3. The app
    The map first. Then the Lock Screen.

    Systems, ATC alerts and messaging, airport briefing, and the logbook followed. Each one flew real legs before it shipped.

  4. TestFlight
    Sim pilots flew the beta.

    Long hauls, pattern work, and Friday nights on VATSIM. Their landings graded the app as much as the app graded their landings.

  5. App Store
    Launching October 8, 2026.

    Cobalt arrives on the App Store for iPhone and iPad. Free to fly, with Peak for pilots who want control and history. Leave your email and we will send a launch code.
