snap2store 0.1.0

Auto add device frames to iOS/iPadOS screenshots for App Store.

Snap2Store

中文文档

Snap2Store is designed for Apple developers to solve the problem that screenshots captured from the iOS simulator cannot be directly used in the App Store.
It automatically adds device frames and adjusts to the required dimensions, making your app screenshots more professional and compliant with App Store standards.

---

Background

Screenshots taken from the iOS simulator cannot be uploaded directly to the App Store because:

• ❌ Sizes do not match App Store requirements
• ❌ Missing device frames, resulting in poor presentation
• ❌ Manual processing is time-consuming and inefficient

This tool solves these problems with one command:

• ✅ Automatically adds real device frames
• ✅ Outputs screenshots that meet App Store requirements
• ✅ Batch processing for improved developer efficiency

---

Installation

pip install snap2store

Usage

Typical Workflow

1. Capture screenshots in the iOS simulator
2. Run the processing tool for the target device
3. Get processed screenshots with the correct frame and size
4. Upload directly to App Store Connect
