+# Simple Weather Service
+
+## Introduction
+
+The Simple Weather Service provides a simple and straightforward API to specify the current weather and the forecast for the next 5 days.
+It effectively replaces the original Weather Service (from InfiniTime 1.8) since InfiniTime 1.14.
+
+## Service
+
+The service UUID is `00050000-78fc-48fe-8e23-433b3a1942d0`.
+
+## Characteristics
+
+## Weather data (UUID 00050001-78fc-48fe-8e23-433b3a1942d0)
+
+The host uses this characteristic to update the current weather information and the forecast for the next 5 days.
+
+This characteristics accepts a byte array with the following 2-Bytes header:
+
+ - [0] Message Type : 
+   - `0` : Current weather
+   - `1` : Forecast
+ - [1] Message Version : Version `0` is currently supported. Other versions might be added in future releases
+
+### Current Weather 
+
+The byte array must contain the following data:
+
+ - [0] : Message type = `0`
+ - [1] : Message version = `0`
+ - [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970)  in local time (the same timezone as the one used to set the time)
+ - [10, 11] : Current temperature (°C * 100)
+ - [12, 13] : Minimum temperature (°C * 100)
+ - [14, 15] : Maximum temperature (°C * 100)
+ - [16]..[47] : location (string, unused characters should be set to `0`)
+ - [48] : icon ID 
+   - 0 = Sun, clear sky
+   - 1 = Few clouds
+   - 2 = Clouds
+   - 3 = Heavy clouds
+   - 4 = Clouds & rain
+   - 5 = Rain
+   - 6 = Thunderstorm
+   - 7 = Snow
+   - 8 = Mist, smog

+  - [10] Number of days (Max 5, fields for unused days should be set to `0`)
+  - [11,12] Day 0 Minimum temperature (°C * 100)
+  - [13,14] Day 0 Maximum temperature (°C * 100)

-By default, apps only do something (as in a function is executed) when they are created or when a touch event is detected.
+Apps can be refreshed periodically and reacts to external events (touch or button).
 
 ## Interface
 
-Every app class has to be inside the namespace `Pinetime::Applications::Screens` and inherit from `Screen`.
+Every app class is declared inside the namespace `Pinetime::Applications::Screens` 
-The constructor should have at least one parameter `DisplayApp* app`, which it needs for the constructor of its parent class Screen.
+and inherits
-Other parameters should be references to controllers that the app needs.
+from [`Pinetime::Applications::Screens::Screen`](https://github.com/InfiniTimeOrg/InfiniTime/blob/main/src/displayapp/screens/Screen.h).
-A destructor is needed to clean up LVGL and restore any changes (for example re-enable sleeping).
-App classes can override `bool OnButtonPushed()`, `bool OnTouchEvent(TouchEvents event)` and `bool OnTouchEvent(uint16_t x, uint16_t y)` to implement their own functionality for those events.
-If an app only needs to display some text and do something upon a touch screen button press,
-it does not need to override any of these functions, as LVGL can also handle touch events for you.
-If you have any doubts, you can always look at how the other apps function for reference.
 
-### Continuous updating
+Each app defines its own constructor.
+The constructors mostly take references to InfiniTime `Controllers` (ex: Alarm, DateTime, BLE services, Settings,...)
+the app needs for its operations. The constructor is responsible for initializing the UI of the app.
 
-If your app needs to be updated continuously, you can do so by overriding the `Refresh()` function in your class
+The **destructor** cleans up LVGL and restores any changes (for example re-enable sleeping).
-and calling `lv_task_create` inside the constructor.

-taskRefresh = lv_task_create(RefreshTaskCallback, LV_DISP_DEF_REFR_PERIOD, LV_TASK_PRIO_MID, this);
+that will call the method `Refresh()` periodically.
+
+## App types
+
+There are basically 2 types of applications : **system** apps and **user** apps.
+
+**System** applications are always built into InfiniTime, and InfiniTime cannot work properly without those apps.
+The watchfaces, settings, notifications and the application launcher are examples of such system applications.
+
+**User** applications are optionally built into the firmware. They extend the functionalities of the system.
+
+The distinction between **system** and **user** applications allows for more flexibility and customization.
+This allows to easily select which user applications must be built into the firmware
+without overflowing the system memory.
+
+## Apps initialization
+
+Apps are created by `DisplayApp` in `DisplayApp::LoadScreen()`.
+This method simply call the creates an instance of the class that corresponds to the app specified in parameters.
+
+The constructor of **system** apps is called directly. If the application is a **user** app,
+the corresponding `AppDescription` is first retrieved from `userApps`
+and then the function `create` is called to create an instance of the app.
+
+## User application selection at build time
+
+The list of user applications is generated at build time by the `consteval` function `CreateAppDescriptions()`
+in `UserApps.h`. This method takes the list of applications that must be built into the firmware image.
+This list of applications is defined as a list `Apps` enum values named `UserAppTypes` in `Apps.h`.
+For each application listed in `UserAppTypes`, an entry of type `AppDescription` is added to the array `userApps`.
+This entry is created by using the information provided by a template `AppTraits`
+that is customized for every user application.
+
+Here is an example of an AppTraits customized for the Alarm application. 
+It defines the type of application, its icon and a function that returns an instance of the application.
+
+```c++
+template <>
+struct AppTraits<Apps::Alarm> {
+  static constexpr Apps app = Apps::Alarm;
+  static constexpr const char* icon = Screens::Symbols::clock;
+
+  static Screens::Screen* Create(AppControllers& controllers) {
+    return new Screens::Alarm(controllers.alarmController,
+                              controllers.settingsController.GetClockType(),
+                              *controllers.systemTask,
+                              controllers.motorController);
+  };
+};

-With `taskRefresh` being a member variable of your class and of type `lv_task_t*`.
+This array `userApps` is used by `DisplayApp` to create the applications and the `AppLauncher`
-Remember to delete the task again using `lv_task_del`.
+to list all available applications.
-The function `RefreshTaskCallback` is inherited from `Screen` and just calls your `Refresh` function.

-/**
- * Different weather events, weather data structures used by {@link WeatherService.h}
- *
- * How to upload events to the timeline?
- *
- * All timeline write payloads are simply CBOR-encoded payloads of the structs described below.
- *
- * All payloads have a mandatory header part and the dynamic part that
- * depends on the event type specified in the header. If you don't,
- * you'll get an error returned. Data is relatively well-validated,
- * so keep in the bounds of the data types given.
- *
- * Write all struct members (CamelCase keys) into a single finite-sized map, and write it to the characteristic.
- * Mind the MTU.
- *
- * How to debug?
- *
- * There's a Screen that you can compile into your firmware that shows currently valid events.
- * You can adapt that to display something else. That part right now is very much work in progress
- * because the exact requirements are not yet known.
- *
- *
- * Implemented based on and other material:
- * https://en.wikipedia.org/wiki/METAR
- * https://www.weather.gov/jetstream/obscurationtypes
- * http://www.faraim.org/aim/aim-4-03-14-493.html
