Splash Screen Guide: How to Make One (Sizes, Tools & Best Practices)

Short answer: A splash screen is the brief branded screen shown while your app loads. On iOS you build it as a launch screen that the system displays instantly; on Android 12+ the system generates it from your app icon and theme. Design it once at your brand's core colors and logo, keep it under a blink, and never use it to fake loading time.

Splash Screen vs Launch Screen

The two terms are used interchangeably, but the platforms differ:

• iOS — Launch Screen: a lightweight, system-rendered placeholder (a storyboard with your logo and background) shown the instant the app starts. Apple's guidance is to make it resemble your app's first screen so the launch feels seamless, and not to use it as a branding splash or to add text that looks like loading UI.
• Android — Splash Screen (API 31+): since Android 12 the system draws the splash automatically from your app icon and windowSplashScreenBackground color. You customize it in the theme; animation and a branded icon are supported, and the official Splash Screen API documentation is the source of truth for icon-safe-zone measurements.

On older Android versions (and in cross-platform frameworks), the classic approach is a fullscreen drawable or a dedicated view — which is where most teams still need a designed asset.

What a Splash Screen Generator Is Good For

A splash screen generator or template tool speeds up the repetitive part: producing the correctly sized logo-on-background assets for every density and orientation from one design. Instead of exporting dozens of near-identical PNGs by hand, you:

1. Design the master artwork (logo + background color, no text that can look like loading UI).
2. Let the tool export the required size set.
3. Wire the assets into your launch storyboard (iOS) or splash theme (Android).

You can do step 1 and 2 in a canvas-based design editor. Our screenshot editor handles the store-side assets (screenshots, the 1024×500 Google Play feature graphic, app store images) from the same brand kit — keep the splash screen's background and logo identical to those assets so the launch, listing and icon feel like one system.

Best Practices That Apply Everywhere

• Keep it minimal: logo, background, nothing else. No taglines, no version numbers, no spinners pretending to load.
• Match the first screen: the closer the splash resembles your app's initial UI, the shorter the perceived launch.
• Respect the safe area: avoid pushing the logo into notch or gesture-inset regions.
• Time-box it: if the app is ready, dismiss immediately. A splash that delays a ready app is an anti-pattern on both platforms.
• Dark mode: provide a dark variant where the platform supports it (Android theme attributes; iOS via trait-specific assets in your storyboard).
• Test on real devices: launch timing differs wildly between a flagship and a four-year-old budget phone.

Common Mistakes

1. Using the splash as an ad. Marketing copy belongs in your store screenshots, not in the launch path.
2. Hardcoding a fullscreen image on modern Android — you fight the system splash and get inconsistent behavior across OEMs.
3. Forgetting tablets and landscape: a portrait-only asset stretches or letterboxes on iPad and Android tablets.
4. Rebuilding assets by hand for every density instead of generating the full set from one master.

Checklist Before You Ship

• Master artwork: logo + brand background only
• Light and dark variants where supported
• iOS launch storyboard set (system-rendered, no code delays)
• Android 12+ theme configured (icon + background color)
• Legacy Android assets generated for all densities
• Verified on at least one small phone, one tablet, and one dark-mode device

A splash screen is a two-second handshake — make it quiet, on-brand and fast, and spend the saved effort on the store screenshots that actually drive installs.
