Momentum App Creator

Create new Flipper Zero applications following Momentum Firmware conventions and best practices.

Context

• Momentum Firmware uses FBT (Flipper Build Tool) for compilation
• Apps are organized in applications/ directory with subdirectories for different categories
• Each app requires an application.fam manifest file
• Apps use Furi framework and GUI system

Instructions

When creating a new Flipper Zero app:

1. Determine app category and location:

   • applications/main/ - Core system apps
   • applications/external/ - Third-party apps
   • applications/debug/ - Debug/development tools
   • applications/examples/ - Example applications

2. Create app structure:

   applications/[category]/[app_name]/
   ├── application.fam
   ├── [app_name].c
   ├── [app_name]_i.h (if needed)
   ├── scenes/ (if using scene manager)
   └── icons/ (if custom icons needed)
   

3. Generate application.fam:

   App(
       appid="app_name",
       name="App Display Name",
       apptype=FlipperAppType.EXTERNAL,
       entry_point="app_name_app",
       cdefines=["APP_NAME"],
       requires=["gui"],
       stack_size=2 * 1024,
       order=10,
       fap_icon="icon.png",
       fap_category="Category",
   )
   

4. Create main C file with:

   • Proper includes for Furi framework
   • App structure definition
   • Entry point function
   • GUI setup and event handling
   • Memory management

5. Follow Momentum conventions:

   • Use consistent naming (snake_case for files, PascalCase for types)
   • Include proper error handling
   • Use Furi logging system
   • Follow memory allocation patterns
   • Include proper cleanup in app exit

Required Includes

#include <furi.h>
#include <gui/gui.h>
#include <gui/view_dispatcher.h>
#include <gui/scene_manager.h>
#include <gui/modules/submenu.h>

Build and Test

• Use ./fbt launch APPSRC=app_name to build and run
• Test on actual hardware when possible
• Verify memory usage and cleanup
