Google Play allows an 80-character short description and 4,000-character full description, while Apple allows a 30-character subtitle and 4,000-character plain-text description. Lead with what the app does in the first sentence and count characters against each limit before submitting.

Apple requires 1 to 10 iPhone screenshots in JPG or PNG. Preferred 6.9-inch portrait sizes are 1320×2868, 1290×2796, or 1260×2736 pixels; if not providing 6.9-inch, use 6.5-inch sizes 1284×2778 or 1242×2688. Apple scales these down to smaller iPhones.

Google Play requires a 512×512 px 32-bit PNG icon with alpha (max 1024 KB), a 1024×500 px feature graphic in JPEG or 24-bit PNG with no alpha, and at least 2 phone screenshots. Screenshots must have a minimum side of 320 px and longest side no more than twice the shortest.

Apple keywords are limited to 100 bytes total, comma-separated with no spaces, and each keyword must be longer than 2 characters. Non-ASCII characters consume multiple bytes, and you should not repeat the app name or category since those are already indexed.

No, the default scope is phone-only listings. Tablet, iPad, desktop, Chromebook, TV, watch, Mac, and visionOS assets are separate asset families with different specifications and are excluded unless the app explicitly supports those platforms.

Claim words like "best", "#1", "free", rankings, awards, and pricing claims trigger rejection in both text and images baked into screenshots or graphics. Screenshots must also show real app UI in use, not splash screens, mockups, or unsupported devices.
