RocketSim enhances the simulator with extra functionality like comparing designs, creating recordings into GIF or MP4, and launching deeplinks/universal links.

Compare Designs for pixel-perfect design implementations
* Create pixel-perfect implementations of your app’s design
* Drag, Paste, or Select images for comparison
* Use the overlay mode to compare your app’s implementation to its design
* The slider allows you to slide between your app’s implementation and its design
* Any image source, whether it’s Sketch, Figma, or Zeplin.

Create professional recordings to share progress
* A popup next to the active simulator allows to start a recording easily
* Enable touches to explain better how your app responds to user interaction
* Export-ready for App Store Connect. Creating App Previews has never been easier
* Landscape orientation is correctly applied in the exported video
* A floating thumbnail with the resulting recording allows to drag into any destination easily
* Select MP4 or GIF to match your needs

Launch and manage deeplinks (Universal Links)
* Launch deeplinks to test routing in your apps
* Easily launch deeplinks from your clipboard
* Manage and share deeplink groups with your colleagues

Each feature is developed with a focus on productivity to keep you in your flow. Configure the available shortcuts to improve this even more.

Really good job!

It makes it so easy to create videos for app previews or just to share with friends or co-workers!

Keep up the great work!
