Screen Time Tracker

Description The project consists of two components:

• API is a background service that tracks screen time spent in various applications and writes the data to a JSON file.
• Qt6 application is a graphical interface that reads data from JSON and displays it in the form of convenient histograms, allowing you to analyze activity by day and week.

---

Features

• Real-time tracking of application usage time
• Saving statistics in JSON with a convenient structure (dates and applications with their time)
• Qt6 GUI with visualization: charts by day and week
• Buttons for switching between daily and weekly viewing modes
• Legend with color-coded applications

---

Technical Details

• The API is written in C++ (or another language if necessary)
• Qt6 is used for charting and interface
• The JSON format is something like this:

{
  "21-06-2025": {
    "Explorer.EXE": 45,
    "WindowsTerminal.exe": 22,
    "devenv.exe": 16
  },
  "22-06-2025": {
    "Explorer.EXE": 3,
    "Telegram.exe": 17,
    "devenv.exe": 59
  }
}
