Cricut has talked about a few benefits of moving from a website to an app:
- Automatic updates that don’t require you to update your plug in (this alone makes it worth it!)
- Faster connection between your computer and your Cricut
- Internet quality will generally not affect using the Design Space app like it can with the website
- Design and cut offline more easily (not sure about this one; see below)
- Updated search capabilities
