Posts tagged device mockups on the mockiso blog: guides, tips and tools for device mockups and app store screenshots.
Most App Store screenshot rejections come from a few fixable mistakes: splash or login screens instead of the app in use, prices or "free" claims, other-platform imagery, real user data, and wrong sizes or transparent PNGs. Google Play adds bans on rankings, awards and promo text.
Use flat mockups when the interface has to be read: the first App Store screenshots, documentation and UI walkthroughs. Use 3D mockups when you need atmosphere and depth: hero images, launch posts, landing pages and later screenshots in the set.
Product Hunt recommends 1270×760 px gallery images, a square 240×240 thumbnail, and files under 3MB, and it needs at least two images before the gallery appears. Treat the gallery as a short visual story: lead with the outcome, show the product in device mockups, and keep every slide consistent.
To submit an iPhone app, App Store Connect requires at least one screenshot for the 6.3-inch Dynamic Island class (1206 × 2622 or 1179 × 2556 px), plus a 13-inch iPad set (2064 × 2752 or 2048 × 2732 px) if your app runs on iPad. You can upload 1–10 JPEG or PNG images per size.
A Google Play feature graphic must be a 1024 × 500 px JPEG or 24-bit PNG with no alpha channel. Keep the focal point centered, use vivid colors, skip device imagery and words like "#1" or "Free," then A/B test it in Play Console.
Use device mockups when you need context: landing pages, launch posts, pitch decks, portfolios and most App Store sets. Skip the frame when a store or platform discourages it, such as Wear OS listings on Google Play, or when the UI needs every pixel.
