Getting Started

Installation

Screenshot Master is available exclusively on the Mac App Store.

1. Open the Mac App Store
2. Click "Get" to install
3. Launch the app from your Applications folder

Create a New Project

When you first open Screenshot Master, you'll see the welcome screen with two options:

• Create New project (Cmd+N) — start a fresh project
• Open Existing Project (Cmd+O) — reopen a previous .smr file

Your recent projects are listed on the right side for quick access.

Add Screenshots

Once your project is created, you'll see an empty canvas. From here you can:

• Drag & drop one or more app screenshots (6.9" or 6.5" size) directly onto the canvas — Screenshot Master will create a screenshot entry for each image
• Click "+" to add an empty screenshot that you'll fill with assets later
• Explore templates to start from a pre-made design

You can drag up to 10 images at once.

Edit Text

Each screenshot can have a title and a subtitle. To edit them:

1. Double-click on any text block in the canvas to enter editing mode
2. Type your text (100 characters max per field)
3. Use the right panel to customize font, weight, size, color, outline, and highlight

You can highlight a word by wrapping it in brackets: [keyword] — it will be rendered with the highlight color you pick in the inspector.

Translate

Screenshot Master supports 43 App Store locales. To localize your screenshots:

1. Add locales from the translation manager (Open button in the right panel)
2. Fill in your default locale text for all screenshots
3. Click "Translate all" to auto-translate every screenshot into all your locales at once

You can also translate manually per screenshot and per locale.

Preview

Before exporting, preview how your screenshots will look:

• Full size — view all screenshots at actual resolution across all formats and locales
• App Store Search — see how the first 3 screenshots appear in search results (light & dark mode)
• App Store Product Page — see how your full set looks on the product page

Hit the Preview button in the bottom-right export bar, or press Cmd+P.

Export

When you're ready, you have two options:

Export to disk

Click Export and choose a format:

• Individual formats: 6.9" iPhone, 6.7" iPhone, 6.5" iPhone, 5.5" iPhone, iPad, Android Phone
• All formats at once

Screenshots are saved as JPG files organized by locale and format.

Upload to App Store Connect

Click Upload to App Store to push your screenshots directly to App Store Connect — the order of your screenshots is preserved. You'll need to configure your App Store Connect credentials first (API key stored in Keychain).

You can also upload to Product Page Experimentation for A/B testing different screenshot sets.
