How to Use Device Bezels in App Screenshots to Drive Conversions

What is a Device Bezel?

A device bezel (often referred to as a mockup or device frame) is the graphical representation of the physical hardware of a smartphone or tablet. In the context of App Store Optimization (ASO), it refers to wrapping your raw, flat app screenshots inside a realistic 3D or 2D image of an iPhone or Android phone.

If you look at the Apple App Store or Google Play Store today, nearly 90% of the top-grossing apps do not upload raw, flat screenshots. Instead, they use stylized graphics where the app UI is displayed inside a beautiful device mockup, surrounded by a background and marketing text.

Why Raw Screenshots Hurt Conversions

Apple and Google allow you to simply take a screenshot on your physical device or simulator and upload it directly. So why go through the effort of adding a device frame?

1. Lack of Context

A flat, borderless rectangle of UI elements can feel abstract. When a user sees a software interface contained within the familiar physical boundaries of an iPhone (complete with the Dynamic Island or notch), it instantly grounds the image in reality. The user can visualize exactly what holding and using your app feels like.

2. Missing the "Why"

A raw screenshot shows the user what your app looks like, but it rarely explains why they should care. By shrinking the screenshot slightly and wrapping it in a device frame, you create negative space on the canvas. This negative space is crucial: it allows you to add large, bold text above or below the device that explicitly states the core benefit of the screen they are looking at.

3. The "Unfinished" Vibe

Uploading raw screenshots signals to the user (subconsciously) that this might be a lower-quality indie app. Premium apps spend time on their presentation. A polished device mockup with a cohesive background gradient immediately elevates the perceived value of your software.

How to Add Device Bezels in ReinShots

Traditionally, wrapping screenshots in device frames required purchasing expensive PSD mockups online, opening Photoshop, navigating smart objects, and manually masking your UI. If you updated a feature in your app, you had to redo the entire process.

ReinShots Studio makes this instant and automatic directly in your browser. Here is how to use the device bezel engine:

Step 1: Upload Your Raw UI

Start by capturing your raw app UI from Xcode Simulator, Android Studio Emulator, or directly from your test device. Drag and drop these images into the ReinShots gallery.

Step 2: Select a Device Frame

Click on the Device tab in the ReinShots editor. Here, you have access to a library of modern, high-fidelity device mockups. The library is constantly updated to include the latest flagship hardware.

• For iOS Apps: Select an iPhone 16 Pro or iPad Pro frame. Ensure you are matching the aspect ratio of the App Store size requirements (e.g., 6.9-inch display).
• For Android Apps: Select a generic modern Android frame or a flagship Pixel/Galaxy model.

Step 3: Choose the Bezel Style

ReinShots offers different styles of bezels to match your brand's aesthetic:

• Realistic 3D: High-fidelity renders with accurate glass reflections, metallic edges, and shadows. Best for premium, professional apps.
• Clay / Minimalist: Flat, matte-colored devices that strip away reflections. Best for playful, colorful, or modern minimalist UI designs.
• Wireframe: Just the outline of the phone. Best when you want absolute zero distraction from the UI itself.

Step 4: Scale and Position

Once the bezel is applied, use the scale slider to adjust how much space the phone takes up. A common best practice is to scale the device up so the bottom edge bleeds off the screen, leaving plenty of room at the top for a massive, readable headline.

Step 5: Export

Because ReinShots understands the aspect ratio of the device frame you selected, it guarantees that your final export will perfectly meet Apple or Google's strict dimension requirements (such as 1290x2796 pixels) without any distortion or stretching.

The "UI-Only" Exception

Are there times when you shouldn't use a device bezel? Yes. If your app has an incredibly dense, data-heavy interface (like a complex financial dashboard or a detailed calendar), shrinking the UI to fit inside a device bezel might make the text completely unreadable on a mobile screen.

In these rare cases, it is acceptable to use a "UI-only" approach, where you simply apply a drop shadow to the raw screenshot and float it on a background, allowing it to take up maximum pixel space. However, for 95% of consumer apps, a device bezel is the proven path to higher conversions.
