Screenshot Bro is a focused screenshot editor for creating polished App Store and Google Play marketing images without rebuilding every layout from scratch in a general-purpose design tool.

Design complete screenshot sets for iPhone, iPad, Mac, Android phones, and Android tablets. Start from a template or build your own layout, drop in screenshots, add device frames, write headlines, adjust backgrounds, localize your text, and export organized files for every screen size and language.

Built for app screenshots, not generic design work.

Key features:

  • Create screenshot sets for App Store and Google Play listings
  • Use built-in templates to start faster
  • Build multi-shot rows for full screenshot campaigns
  • Batch-import screenshots into a row
  • Add device frames for supported iPhone, iPad, Mac, and Android layouts
  • Design with text, shapes, images, gradients, tiled backgrounds, and SVG graphics
  • Style text with rich formatting and custom fonts
  • Fine-tune alignment, spacing, sizing, and layout directly on the canvas
  • Manage locale-specific text and image overrides
  • Auto-translate missing text and track translation progress
  • Export PNG or JPEG files into organized folders by locale and row
  • Keep projects local by default
  • Sync projects across Macs with iCloud when enabled
  • No tracking

Screenshot Bro is made for indie developers, product teams, designers, and marketers who need more control than a basic screenshot generator and a faster workflow than manually rebuilding every app marketing image.

Create better app store screenshots, faster.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
