Fluid UI vs Mockapp

Fluid UI is a web-based tool for making, previewing, sharing, and exporting mobile app mockups. It supports interactive web and mobile prototypes with taps, swipes, clicks, and other gestures, plus page effects such as fades, flips, and pop-ins. The built-in library contains more than 2,000 components spanning Material Design, iOS, Windows, and wireframe styles. Teams can collaborate on cloud-saved projects in real time. Reviewer mode supports shared click-throughs, chat, annotations, and comments, and the service also supports remote user testing sessions. Fluid UI runs in Firefox and Chrome, offers an installable desktop client, and has Android and iOS preview apps. There is a free plan and a free trial. Paid plans include Solo at $8.25 a month for five active projects, one user license, and unlimited reviewers; Pro is $19.08 a month, and Team is $41.58 a month.

Mockapp turns UI designs into installable mobile prototypes for previewing and testing interfaces before development. It accepts designs from Figma, Sketch, Adobe XD and Canva through a no-code workflow that requires no coding or technical skills. Mockapps install on iOS and Android, and each has a unique link that collaborators can use without a third-party app or account. A feedback system lets collaborators respond to prototypes. Live Update applies design changes to an already installed Mockapp without another collaborator action. Smart UI is described as AI that interprets a design to make prototypes more realistic. The product is presented for startup founders, UI/UX designers and digital agencies. Its Free plan costs nothing and allows as many Mockapps as wanted, with testing, sharing and installation without limitation. Mockapp currently does not export prototype code, so its workflow ends at prototype preview and testing.
