A device mockup is a photorealistic image of a phone, laptop, tablet, or watch with your design displayed on its screen. Designers use device mockups for App Store screenshots, landing page heroes, marketing ads, and social media assets. Modern tools like MochiMockup render each mockup in real 3D rather than compositing a flat screenshot onto a static device photo.
Why designers use device mockups
A raw screenshot of an app is hard to parse. It looks abstract, it has no physical context, and it doesn't match the way people actually experience the product. Dropping the same screenshot onto a 3D phone render instantly makes it feel real — visitors understand "this is an app" without having to think about it.
The three main use cases
- 01App Store and Google Play screenshots — Apple research shows 73% of visitors only read the first two screenshots on a product page, so a strong mockup in slot #1 directly drives installs.
- 02Landing page hero images — a tilted phone or floating laptop is the fastest way to make a web app feel tangible above the fold.
- 03Social media and marketing ads — LinkedIn, X, and Instagram posts that include a device mockup outperform raw screenshots in engagement (LinkedIn B2B benchmarks, 2024).
Flat composites vs. real 3D renders
Not all device mockups are created equal. The older generation of tools uses flat PSD or PNG composites — essentially a photograph of a phone with a blank screen, onto which you paste your screenshot. Newer tools like MochiMockup render every scene in real 3D, which means the screen respects the device's curvature, the lighting is physically accurate, and reflections from UI elements appear correctly on the glass.
| Approach | Flat composite | Real 3D render |
|---|---|---|
| Lighting accuracy | Fixed, may clash with UI | Physically based |
| Screen curvature | Flat | Respects device geometry |
| Reflections | Baked into the photo | Generated per screen |
| Editability | Stuck with the angle the photo was shot | Live camera control |
| Typical tools | Mockuuups Studio, Mockup Photos | MochiMockup, Rotato, Shots.so |
Who invented device mockups?
Device mockups have existed since the first iPhone launched in 2007 — Apple's own product photography became the template every designer borrowed. The first dedicated mockup tool (Placeit) launched in 2014, and the category has since split into two branches: photo-based libraries (Mockuuups Studio, Mockup Photos) and 3D-native tools (Rotato, Shots.so, MochiMockup).
“A good device mockup is the difference between visitors understanding your product in half a second or scrolling past it. Every SaaS landing page needs at least one.”
How to create your first device mockup
- 01Export your app screen at 2x or 3x from Figma as PNG.
- 02Open MochiMockup and pick a device category — phone, laptop, tablet, or watch.
- 03Drag your PNG onto the device; the screen snaps into place.
- 04Pick a scene (studio, lifestyle, gradient).
- 05Export at 2K (free) or 4K (Pro) and drop it into your landing page, App Store listing, or ad creative.
