    Base44 App Store Listing: Screenshots, Keywords and Copy That Convert

    Quick answer

    A converting Base44 App Store listing needs one 6.9-inch iPhone screenshot set (1290 x 2796 px) whose first three images sell the main outcome and top two features, a 30-character name and subtitle that carry your best keywords, a 100-character keyword field with no repeated words, and a description whose first three lines lead with the benefit.

    Approval gets you listed. The listing gets you downloads.

    Most people decide whether to install from the first three screenshots, without reading anything. For a Base44 app, where the product is often new and unknown, the listing does the selling.

    Screenshots

    You need one set at 6.9-inch iPhone size (1290 × 2796 px); Apple scales it down for smaller phones. Add the 13-inch iPad size only if you support iPad. Details in our screenshot sizes guide.

    • Screenshot 1: the main outcome in five words or fewer, over your best screen.
    • Screenshots 2–3: the two features people pay for.
    • Screenshots 4–6: proof — results, ratings, security.

    Show real app screens. Apple rejects screenshots that show features the app doesn't have.

    Name and subtitle

    You get 30 characters for each, and both count toward search ranking. Use the name for brand plus one keyword ("Flowly: Habit Tracker") and the subtitle for the benefit ("Build routines that stick").

    Keyword field

    100 characters, separated by commas, with no spaces. Don't repeat words already in your name or subtitle, and skip plurals — Apple matches them. Aim for specific phrases with less competition over broad terms you can't win. Tools like appXL help you find these.

    Description and promotional text

    Only the first three lines show before "more", so lead with the outcome. Promotional text (170 characters) can be updated without a new review — use it for launches and offers.

    Preview video

    Optional, but a 15–30 second video that autoplays can raise installs. Record it from the app itself — Apple rejects footage that isn't from the app.

    Checklist before submitting

    1. Screenshots match the current build.

    3. Privacy policy and support URLs work.
    4. Age rating answered honestly.
