1. Figma

Best for: Designers and teams who want to preview mockups on a phone.

Figma is a design and collaboration platform with companion apps for iPhone and Android. You can open your prototypes and mockups on a device instead of judging them on a desktop screen.

Real-device testing is the standout feature, and it's why Figma tops this list. That verdict comes from the listing, not hands-on testing.

2. Lovable

Best for: People who want a mockup turned into a working app.

Lovable is an AI tool that turns mockups and prompts into working applications. A 2026 guide to mobile app mockup tools named it.

Its standout feature is going from mockup to working app. That's a different job from pure design tools, so don't expect a traditional drawing workflow.

3. Uizard

Best for: Fast concept mockups with AI help.

Uizard is an AI-assisted design tool for generating app mockups and concepts. If you need something to show quickly, it gives you a starting point without drawing every screen.

AI-generated mockups are its standout feature. A 2026 guide to mobile app mockup tools included it too.

4. MockFlow

Best for: Moving from wireframes to finished mockups in one tool.

MockFlow takes a design from rough wireframe to polished mockup. Once the layout is settled, you don't have to rebuild your work in a second program.

That single path from wireframe to mockup is the standout feature. A 2026 guide to mobile app mockup tools named it.

5. Marvel

Best for: Beginners who need quick prototypes without design skills.

Marvel focuses on prototyping and keeps the barrier to entry low. If you've never touched a design tool, it's a gentler start than most.

Its standout feature is quick prototyping with no design background needed. A 2026 guide to mobile app mockup tools listed it as well.

6. Moqups

Best for: People who want diagrams and mockups in one place.

Moqups combines diagramming with mockup tools, so flowcharts and screen designs can sit side by side.

Its standout feature is a set of iOS and Android stencils plus Material Design icons. They help your mockups look like native screens.

7. Sketch

Best for: Mac-based design teams building app mockups.

Sketch is a Mac-native design tool that design teams use to build app mockups. The native Mac environment is its standout feature.

One plain warning: it's Mac-only. If you're on Windows or Android, look elsewhere.
