Rabbi Ovadiah Yosef Calendar App

The "זמני יוסף - R' Ovadia Zmanim" application is a comprehensive Jewish zmanim calendar designed according to the teachings of Rabbi Ovadiah Yosef ZT"L and the Yalkut Yosef. The calculations are meticulously derived from the Ohr HaChaim calendar, which Rabbi Ovadiah created in the 1990s alongside HaRav Shlomo Benizri and HaRav Asher Darshan. This calendar was used by Rabbi Ovadiah throughout his life and continues to serve as a reliable source for zmanim.

Features

This app includes an extensive range of zmanim, ensuring that users have access to all the necessary times for their daily prayers and rituals. Some of the key zmanim featured include:

• Alot Hashachar/Dawn
• Misheyakir
• Sunrise
• Latest time for Shma (MG"A and GR"A)
• Latest time for Brachot Shma
• Chatzot
• Mincha Gedolah, Ketana, and Plag HaMincha
• Sunset
• Tzait Hacochavim
• Rabbeinu Tam
• Weekly Parasha
• Birchat HeLevana
• Birchat HaShemesh
• Mashiv Haruach/Morid Hatal
• Tachanun

Additionally, there is an option in the settings to display zmanim according to the Luach Amudei Horaah, created by Rabbi Leor Dahan Shlita. This calendar is particularly useful for those living in more northern or southern regions outside of Israel.

User-Friendly Design

The app features a "Shabbat/Chag Mode," allowing users to easily view zmanim during Shabbat and holidays. For those who prefer a hands-free experience, the Wear OS/watch application provides real-time zmanim directly on your wrist. Watch tiles and complications are also available for quick reference.
