How to prepare App Store screenshots before launch

App Store screenshots are not just images. They are a small sales page inside your listing. This guide helps indie developers plan screenshot captions, sizes, localization, and ASO messaging before opening a design tool.

Before you design, write this down

  • Who is this app for?
  • What painful task does it make easier?
  • What is the first result users care about?
  • What proof can the interface show?
  • What doubt will stop someone from downloading?

Step-by-step App Store screenshot workflow

  1. Step 1

    Start with the store promise

    Write one sentence that explains the result your app creates. This becomes the message behind the first screenshot.

  2. Step 2

    Map one benefit to each screenshot

    Do not make every image a feature dump. Use each screenshot to answer one buyer question.

  3. Step 3

    Check screenshot dimensions early

    Pick the App Store device groups you need before designing, so you do not waste time rebuilding assets.

  4. Step 4

    Write captions before designing

    Short captions force clarity. If the caption is confusing, the screenshot will probably be confusing too.

  5. Step 5

    Localize the message, not just the words

    For each target market, adjust the benefit, tone, and examples instead of translating blindly.

  6. Step 6

    Review the first three screenshots as a funnel

    The first screenshot should create interest, the second should prove usefulness, and the third should reduce doubt.

Caption examples: weak vs stronger

Strong screenshot captions usually describe the result users get, not the internal feature name.

Weak example 1

All your notes in one place

Stronger example 1

Capture ideas before they disappear

Weak example 2

Advanced AI features

Stronger example 2

Turn raw notes into a launch plan

Weak example 3

Easy to use

Stronger example 3

Plan your week in under 5 minutes

A practical first-three-screenshots structure

Screenshot 1

Main outcome

Show the biggest user benefit in plain language.

Screenshot 2

Workflow proof

Show how the app helps users reach that outcome.

Screenshot 3

Trust reducer

Show speed, simplicity, privacy, accuracy, or saved time.

Common mistakes

Writing captions that repeat the app name instead of explaining value.
Using tiny UI screenshots that cannot be read on a phone.
Designing every screenshot before deciding the launch story.
Localizing screenshots word-for-word without adapting the message.
Forgetting to check required device sizes until submission day.

FAQ

What should the first App Store screenshot say?

Lead with the strongest user outcome. A good first screenshot tells people what they can achieve, not just what the app contains.

How many screenshots should an indie app prepare?

Prepare at least three strong screenshots for launch. More screenshots can help, but weak extra images often dilute the message.

Should screenshots focus on features or benefits?

Use the interface as proof, but make the caption benefit-led. Users buy the result the feature creates.

When should I localize App Store screenshots?

Localize after the core English message is clear. Otherwise you will multiply unclear copy across every market.
