Pocket Code vs Stencyl

Pocket Code is a free Android and iOS app for building programs, games, animations, and stories with visual, Lego-like Catrobat programming bricks. Its blocks include if-else statements, loops, variables, mathematical functions, and access to phone sensors. Users can browse, download, review, and remix community programs in the Explore section and on pocketcode.org. Hardware extensions connect Arduino boards, LEGO Mindstorms robots, Phiro robots, and Raspberry Pi projects. Arduino works over Bluetooth for changing digital and PWM pins and reading analog pins. Mindstorms connects robots over Bluetooth for programming and control, while Raspberry Pi bricks read and set pins for IoT programs. Catrobat presents the app for constructive learning and classroom use, with project-based learning and computer-science topics. A wiki and free English- and German-language MOOC provide learning support. Project hosting is no longer offered as a service, although the media library remains available through the wiki. The nonprofit open-source project is driven by the International Catrobat Association and Graz University of Technology’s Institute of Software Technology.

Stencyl is game creation software for making mobile, web, and desktop games with visual logic or custom code. Its drag-and-drop designer uses snapping blocks and includes hundreds of ready-to-use blocks. Creators can also make and share blocks, import libraries, extend the engine with code, and write Haxe classes that work with block-based Behaviors. The Scene Designer provides selection, zooming, grid-snapping, and flood fill; the Actor Editor adjusts appearance, behaviors, and physical properties. Stencyl targets iOS, Android, Windows, Mac, Linux, and HTML5. The free Starter edition publishes HTML5 games and lets users test games on paid target platforms, but cannot publish desktop, iOS, or Android games and displays Stencyl branding. Indie costs $99 a year and adds web and desktop publishing without watermarks. Studio costs $199 a year and includes publishing to iOS and Android, ads, leaderboards, in-app purchases, and third-party plugins. Publishing iOS games to the App Store requires an active Apple developer license and a Mac. Stencyl says it collects no royalties on games.
