RocketSim for Teams

How can I get my manager to approve RocketSim?

Use the RocketSim manager approval guide for a copyable request, a simple payback summary, and answers to common procurement questions.

I installed RocketSim from the App Store. How do I activate my team license?

Installing the app doesn’t unlock RocketSim Pro for team members. Sign in through the activation link and click Activate your seat. If RocketSim doesn’t open, you can enter your license key manually. The activation guide covers both options.

I got a new Mac. How do I move my team seat?

Each Mac uses one seat, so unlink your old Mac first. A team manager can do this in the Teams dashboard under Settings → Users with Unlink device. Then activate your new Mac.

How do I renew my team license or update payment details?

Sign in to the Teams dashboard and go to Settings → Subscription. From there, you can re-subscribe after your license expired or was canceled, update a payment method that failed, add seats, and download invoices. The team subscription guide walks you through each step.

RocketSim says my payment is due. What should I do?

If you’re a developer, let your team manager know — they’re the only ones who can pay. If you’re the manager, sign in to the Teams dashboard and pay the open invoice. RocketSim keeps working while the message shows, and nothing is deleted if the license is deactivated. The payment due guide has a copyable message for your manager and the steps to pay.

Screenshots & Recordings

Why is my video not accepted by App Store Connect?

The videos are optimized for App Previews following these specifications. App Store Connect does not accept each device, so your selected Simulator could not support App Previews. Make sure to use a Simulator matching a device from the App preview specifications.

I only get JPEG images, how can I get PNG images again?

You’ve likely enabled App Store Connect (ASC) Optimization. ASC requires JPEG images without alpha layer. Disable the option and you should get PNGs again.

Can I create transparent captures?

Yes, make sure to disable App Preview Optimized and set your background color to transparent.

Permissions & Troubleshooting

Why does RocketSim need screen recording permissions?

As a developer, I know how important it is to not just use any permissions. Adding the requirement for screen recording permissions was something I disliked, but it was unavoidable. RocketSim is sandboxed and can’t read NSWindow titles without screen recording permissions. RocketSim needs to read the title of the Simulator windows to determine the currently active Simulator.

Network Speed Control isn’t working for me, what can I do?

This is usually caused by missing system permissions.

1. Quit Xcode, all Simulators, and RocketSim, then reopen them.

   (This often fixes the issue after Xcode or macOS updates.)

2. Open System Settings → Privacy & Security and approve any pending RocketSim permissions.

3. Open System Settings → Network → Filter and verify whether RocketSim is present & enabled

4. On macOS Sequoia (15) and later, enable the Network Extension:

   • System Settings → General → Login Items & Extensions
   • Find RocketSim, click (i), and enable Network Extension You may need to approve permissions more than once.

5. Still not working? Do a clean reinstall:

   • Delete RocketSim.app from Applications
   • Empty the Trash and reinstall RocketSim

6. If it still doesn’t work, run systemextensionsctl list and email the output to support@rocketsim.app

About RocketSim

Why wouldn’t I just use xcrun simctl?

Yes, RocketSim uses xcrun simctl as well, but it enhances the output and provides interfaces for quicker access. Recordings, for example, are enhanced with touches and device bezels that you won’t get through the command line tools.

Where can I follow active development?

RocketSim is developed by Antoine van der Lee. You can follow him or the official RocketSim Twitter Account for updates about development.

Where can I report bugs or feature requests?

Issues and feature requests are managed on GitHub.
