Kajj

[edit]

Kajj is a mobile application developed by the Lithium Team that provides real-time notifications about school closures across Iran. It is designed for the Android platform and is available through local marketplaces such as Myket as well as the app’s official website.[1][2]

The app uses a combination of official government updates, weather and air quality data, and media monitoring—including from social platforms—to provide timely alerts to users. Its core audience includes students, parents, and educators who need fast and localized information about school operations during disruptive events such as air pollution, snowstorms, or emergency shutdowns.

Background and Purpose

[edit]

In Iran, school closures due to environmental or public safety concerns are common, but announcements can often be delayed or inconsistently communicated. Kajj was created to address this issue by centralizing and streamlining the distribution of closure information. Its developers use automation and natural language processing (NLP) to monitor and analyze news from education authorities, national weather services, and trusted news agencies like the Iranian Students News Agency (ISNA).[1][2]

The app also integrates crowd-sourced and social media signals to supplement its official data sources, helping users stay informed even when formal announcements are delayed.

Features

[edit]

Kajj includes several core features intended to improve user awareness and responsiveness:

  • Localized alerts: Users receive real-time push notifications specific to their selected province or city.
  • Data aggregation: The app collects and analyzes information from multiple sources, including weather forecasts, air quality indices, and education board announcements.
  • Interactive map: School status across provinces is visualized on a map using color-coded indicators to represent different levels of closure (e.g., partial or complete shutdowns).
  • Personalization: Users can customize which areas and school levels they want updates for, including filters for elementary, middle, or high school closures.
  • Multilingual support: The app is available in both Persian and English, broadening accessibility for different user demographics.

Additional features include a support contact system through the official website.

Availability and Reception

[edit]

As of June 2025, Kajj is available exclusively for Android users and has been downloaded over 600 times on Myket, where it holds a 4.9-star rating.[2] The app has been positively received for its speed and accuracy in alerting users to last-minute school closures, especially during periods of high air pollution in cities like Tehran and Tabriz.
