What's a good iOS app for quickly prototyping user interfaces and sharing them with a team?

Figma is an excellent choice for prototyping user interfaces and collaborating with a team, even on iOS. While the Figma iOS app functions mainly as a viewer, it's incredibly useful for accessing your design files on the go, presenting prototypes to stakeholders, and gathering feedback from your team. You can easily navigate through your designs, interact with prototypes to test user flows, and leave comments directly within the app. This makes it simple to iterate on your designs based on real-time feedback, no matter where you are. The ability to share prototypes via a link also streamlines the review process, allowing team members to view and comment on your designs from their own devices. While you can't directly edit designs within the iOS app, it's a valuable tool for staying connected to your projects and keeping the design process moving forward.
