رباعیات خیام (Rubaiyat Khayyam) is a beautifully presented collection of rubaiyat by the famous Iranian philosopher, mathematician, astronomer, and poet, Hakim Omar Khayyam. The app features a variety of Iranian fonts and backgrounds, making it visually appealing. The app is user-friendly, as it allows users to easily navigate through the poems by double-tapping the screen. Other features include the ability to search for specific poems, save images without additional margins to use as backgrounds, and share poems via SMS, email, Telegram, WhatsApp, and more. The app also offers a night study mode with a black background and the option to change the font size and distance between the lines. Additionally, users can adjust the screen brightness within the app and enable the "always on" screen to prevent it from shutting down after a certain time. The app also offers widgets for the background, which can be updated every few hours to display a new poem without having to open the app.
