Enhancing the iOS Simulator

Compare designs, show rulers, add a grid, quick actions for recent builds. Create recordings with touches, trim and export them into MP4 or GIF and share them anywhere using drag & drop. Add bezels to screenshots and videos.

And that's not all. Organise and launch Universal Links (deeplinks) with ease.

Recent builds

Quick actions for your recent builds help you increase productivity

  • Open common directories like your app's documents folder.
  • Read and write user defaults
  • Grant, revoke, or reset permissions like photo and location access, allowing you to quicker test related implementations

Rulers

Horizontal and vertical rulers give you precise control. Coordinates are shown in on-device pixels so you know exactly where elements are placed.

Grids

Use the grid overlay to perfectly align elements across the screen. Change the color and spacing to match your needs.

Compare designs

Pixel-perfect implementations of delivered designs. Add your designs in the compare tool and verify your implementation, right in the Simulator.

Professional recordings & screenshots

Capture MP4, GIF, or PNG.

  • You'll blow away your colleagues after adding device bezels to your recordings
  • Touches make a difference in telling a story. Share professional recordings of a new feature with your friends and colleagues
  • Optimize for App Store Connect App Previews and stop wasting time using tools like FFmpeg to conform to the App Preview specifications
  • Add bezels to your screenshots for a professional impression

Floating windows for quick access

Stack multiple captures in floating windows and drag them into any destination.

  • Copy your capture to your clipboard and paste anywhere
  • Use the trimmer to get the exact result you're looking for
  • Store your captures in a configurable destination using the save action

The Power of Drag and Drop

App Store Connect. GitHub. Slack. Twitter. iMessage.

Drag your recorded MP4 or GIF into any destination. Use it as an App Store Preview video or share a visual representation inside GitHub issues and pull requests. Directly share what you're working on in Slack or on Twitter.

Everything you need, right from the statusbar

RocketSim keeps things simple. Access all actions right from the statusbar, without any disturbing windows.

Trigger deeplinks

Directly launch universal links that you just copied or select one from your stored groups.

Recent builds

Grant, revoke, or reset permissions. Open common folders or edit user defaults.

Capture recordings & screenshots

Create MP4 and GIF recordings or capture a screenshot.

Using your active simulator

All actions perform in the visible Simulator, simple as that.

Frequently Asked Questions

Can I buy team licenses as well?
Yes you can! Find out more.
Why is my video not accepted by App Store Connect?
The videos are optimised for App Previews following these specifications. App Store Connect does not accept each device, which means that your selected Simulator could not support App Previews. Make sure to use a Simulator matching a device from the App preview specifications.
Why wouldn't I just use xcrun simctl?
Yes, RocketSim uses xcrun simctl as well but 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.
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 Simulator windows to determine the currently active Simulator.
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 around development.
Where can I report bugs or feature requests?
Issues and feature requests are managed on GitHub.
