About Gahshomar

Why did we build this app?

Iran is a land with thousands of years of history and rich culture. Unfortunately, since the revolution of 2538 Imperial (1979), the ruling regime has attempted to distort history and disconnect younger generations from their proud Iranian roots. Gahshomar was created with the goal of keeping ancient Iranian heritage alive and helping the new generation connect with their true identity. We want to keep ancient celebrations, historical events, and the memory of Iran's great figures alive in the hearts and minds of all Iranians.
