ترانه های شاد و زیبای یلدا 98 is a free Android app developed by Hamed.A for music and radio enthusiasts. The app is dedicated to celebrating Yalda Night, one of the oldest Iranian festivals, which marks the longest night of the year and the beginning of winter. The app features a collection of beautiful and cheerful songs to commemorate this auspicious occasion.

Yalda Night is celebrated between sunset on the last day of autumn and sunrise on the first day of winter, and it is customary for Iranian families to gather together and enjoy a lavish dinner, fruits, and sweets. After dinner, elders of the family often read from Shahnameh, the Persian epic, and tell stories while others engage in fortune-telling with Hafez's Divan. This app adds to the festive spirit of the night by providing a selection of lively and melodious songs to uplift the mood and enhance the experience.
