one Operating System
Consolidate your simming

efbX runs on your PC or smart device to give you an airline-inspired EFB experience, whilst taking away the stress of having to launch loads of apps and open tens of tabs just to go flying.

In real life, we show up, brief, fuel, board and go. This is our mission for flight simulation. Remove the immersion breaking admin.

Realistic Workflow

Sip your coffee on your sofa whilst briefing for your flight like a real pilot.

Launch your sim from your phone or tablet, grab your hat and show up to work (or simulator room) like a real pilot ready to go.

efbX has been created by a real world airline captain - this means efbX has exacting realism standards at its core.

One App Store

No two pilot's EFBs are the same, they need tools for work, for fun, for downroute.

Install the apps you want, on demand. Operational tools, news, games, and third party integrations.

Apps talk to one another and also have two way communication with your aircraft and GSX offering a seamless Gate to Gate experience.

Multi platform

We know not everyone has the latest iPads laying around, that's why we've made this cross platform, enabling you to do everything you would on your desktop, direct on any smart device.

Want the to launch your sim, manage your fuel and payload, take screeshots, track your flights all directly and instantaneously from your phone? efbX is for you.

FAQ

Frequently asked questions

When is efbX launching?

At FlightSimExpo 2026, we announced our release window of Q4 2026. More details on the launch will come closer to the time, but if you are on the early access list you will get your download link ahead of general release!

Is it only for iOS?

Not at all - efbX is multi-platform and not just for Apple users. As long as your device is smart it'll work, so if you are an Android user, Apple user or prefer to only run it on your PC, you can enjoy efbX too!

Do I need a tablet?

No - efbX is designed for desktop, tablet and mobile devices across your local network, we thoroughly recommend one though, it makes it so much better!

Is there be beta access?

Yes. Applications for the Beta Program are currently OPEN - You can apply here. Please note: You must be over 18 to take part, as we will require you to sign a Mutual Non-Disclosure Agreement

How much will efbX cost?

Installing and running efbX is completely free of charge. And our base tier is also entirely free. If you wish to upgrade to premium, you can do at any time, details regarding pricing and tiers will come at a later date.

Since many apps in the App Store are developed by third parties, we cannot predict their pricing. The amount you choose to spend on additional apps will depend entirely on your preferences and needs.

Which sims are supported?

We officially support MSFS2020 and MSFS2024. Prepar3D also works in many areas, however we do not guarantee compatibility.

With that said, efbX is a standalone product and will still run without sim connectivity, so you can still use it if you are not using one of our supported sims. X-Plane compatibility is planned post-release.

Will it include charts?

Our chart offering will be announced closer to launch. We can't say much more than that for now, but just know we are on it!

Katie, developer of efbX
About the developer

Built by a real-world Airbus captain.

Hey! I’m Katie, also known as KatiePilot, the developer behind efbX. I’ve been flying commercially for nearly a decade and have spent the last six years developing in the flight simulation space.

You may have come across some of my past work on the Fenix A320, iniBuilds A310, and through other utilities I’ve made over the years.

I kept noticing the same problem in flight sim: we’re missing the very tools I rely on every single day when flying for real. As more people now fly with dedicated hardware, yokes, throttles, and full cockpit setups, interacting with tiny in-game tablets feels more limiting than ever.

So I created efbX - something designed to help all of us enjoy the sim more, while bringing it one step closer to the realities of real-world flying.

I really hope you enjoy it. Katie signature
