What You'll Need
Before you start, make sure you have:
- Raw app screenshots captured from iOS Simulator, Android Emulator, or a physical device
- A modern web browser (Chrome, Edge, Firefox, or Safari)
- Your marketing copy — short, benefit-focused headlines for each screenshot
- ReinShots Studio — free to use, no signup required
Step-by-Step Tutorial
Capture Raw Screenshots
Take screenshots directly from iOS Simulator (⌘ + S) or Android Emulator (camera icon). Capture at the native device resolution — don't resize or crop. You want the highest quality source images possible. For iPhone, target the 6.9" display resolution (1320 × 2868 px). For Android, 1080 × 1920 px is the standard.
Upload Screenshots to the Studio
Open ReinShots Studio in your browser and drag-and-drop your screenshot files into the gallery area. You can upload all your screens at once — the studio organizes them into a connected sequence automatically. All processing happens locally in your browser. Your screenshots are never uploaded to any server.
Choose a Panoramic Background
This is what separates professional app screenshots from amateur ones. Select a vibrant gradient or upload your own background image. ReinShots' panoramic engine calculates the exact slice positions so your background flows seamlessly across all screenshot panels — creating a connected, visually cohesive gallery that draws the eye across your entire listing.
Add Device Bezels
Wrap your raw screenshots in realistic device frames. Choose from the latest iPhone, Android phone, and tablet bezels in multiple color finishes (Space Black, Silver, Natural Titanium). Device bezels add depth and professionalism — they signal to users that your app is a polished, high-quality product.
Write Compelling Caption Text
Add headline and subtitle text above or below each device mockup. Focus on benefits, not features. Instead of "Built-in Calendar", write "Never Miss a Deadline Again". Keep text large enough to read in thumbnail view — remember, users browse the App Store on their phones. Use custom fonts and adjust sizing to match your brand.
Export at Exact Dimensions
Click the export button and choose your target platform preset. ReinShots generates pixel-perfect PNG or JPEG files at the exact dimensions required by App Store Connect or Google Play Console. You can export individual screenshots or batch-export all screens as a ZIP file.
The entire workflow — from uploading raw captures to having submission-ready assets — takes less than 5 minutes with ReinShots Studio. Since everything runs locally in your browser, there's zero server queue or upload time.
Pro Tips for Higher Conversion Rates
- Front-load your value proposition. The first screenshot is the most viewed — make it your strongest selling point.
- Use social proof. If you have awards, ratings, or press mentions, include them in your first or second screenshot.
- Show real app screens. Apple and Google reject heavily modified screenshots that don't represent the actual app.
- Test with localization. If your app supports multiple languages, create localized screenshot sets. Localized listings see up to 30% higher conversion in non-English markets.
- Update regularly. Fresh screenshots signal an actively maintained app. Update your screenshots with each major release.
- Keep text readable at thumbnail size. Preview your screenshots at the size they appear in search results (roughly 150px wide on phones). If the text is unreadable, make it larger.
Common Mistakes to Avoid
- Using raw simulator captures without any design. Bare screenshots look unprofessional and fail to communicate your app's value.
- Too much text per screenshot. Each panel should communicate one clear benefit. Don't cram multiple features into a single screenshot.
- Wrong aspect ratios or dimensions. Even one pixel off can cause App Store Connect to reject your submission. Always use exact presets.
- Outdated device bezels. Using an iPhone 6 bezel in 2026 signals an abandoned app. Use current-generation device frames.
- Ignoring iPad and tablet. If your app supports tablets, create separate tablet screenshots. Tablet users are often higher-value customers.
