Enhancing the Xcode Simulators

Compare designs, show rulers, add a grid, quick actions for recent builds. Create recordings with touches & audio, 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. Scroll down to explore all features.

"I use RocketSim a lot to create recordings for my articles. The touches now make it even easier to share my learnings."

"Recordings with touches and high-quality GIFs from RocketSim are exactly what I need to show what I’m working on."

Network Monitor

Inspect Network Requests in realtime

Explore JSON responses, request headers, metrics, copy cURL requests, and much more.

Compare designs

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

Grids

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

Rulers

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

User Defaults Editor

Edit Standard & Group User Defaults in realtime

Test how your app responds to User Defaults changes. Quickly switch states like User Defaults-driven experiments.

Quick Actions

Configurable actions for Deeplinks (Universal Links) and Push Notifications. Control permissions.

  • Bundle Identifier based: actions automatically show up for recent builds
  • Quickly test Locations, Push Notifications, and Deeplinks
  • Grant, revoke, or reset permissions like photo and location access, allowing you to quicker test related implementations

Location Simulation

Single locations or automobile and walking routes: Test them right in the Simulator.

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

Simulator Airplane Mode

How does your app work without a connection?

Only your Simulator app gets disconnected. You can still use your Mac's connection to search Stack Overflow or share your progress via Slack.

Magnify for precision

Hold ⇧ Shift and move mouse or scroll wheel to magnify

Use the Color Picker and copy the value as SwiftUI Color, NSColor, or UIColor code.

Environment Overrides

Make your app accessible by using environment overrides like inverted colors or changing the dynamic type size.

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
  • Record audio to make it complete

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

09:41 - A historical moment in time

Did you know all iPhones in Apple's keynotes are set to 09:41?

  • Configure your Simulator's status bar to match Apple's keynote designs
  • Customize the status bar into charging mode or using the 5G network

A RocketSim recording in action

Touches + Bezels = Professional Recording.

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.

RocketSim Insights

Increase the productivity of your whole team

Team Insights

Build Apps Faster with your whole team

What's the build duration across the team? Does an M3 Max make a difference in terms of compilation time? With team insights, you'll be able to optimize productivity based on real build data.

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.
