זמני יוסף - R' Ovadia Zmanim 4+

A zmanim app according to Rabbi Ovadiah Yosef ZT"L! Based off of the Ohr HaChaim calendar in Israel that Rabbi Ovadiah himself created and used until he passed.

We are the platform to use whenever and wherever you'd need Halachic Times (Zemanim) according to Maran Rabbeinu Ovadia Yosef zt'l, following his practices represented in the Ohr Hachaim calendar (לוח אור החיים). The astronomical science behind his calendar was studied and reproduced to fit as needed when extending beyond the Eretz Yisrael borders, while keeping the rulings the same in Eretz Yisrael.

- Simple setup: Select your location (GPS, name/zip code or advanced) & language (Hebrew or English; translated or transliterated). No internet required for further use of the app.
- Use our notifications to stay on top of the changing times! They are customizable to trigger when you want them to.
- Add a home-screen widget to see immediate details (Hebrew Date, Tachanun, Special-Day - like Omer, next Zeman) outside of the app.
- Extend the times from the phone to your wrist, with our Watch OS app. Open the app to immediately see the next Zeman without any other distractions and scroll to see the others.
- Explore calendar-day relevant learning material, with our Daily Limud schedule (includes Daf Yomi, Mishna Yomi, Tehilim Yomi, etc). One quick tap will send you to Sefaria, to find commentaries, connections and other details that will enhance the learning.
- Shabbat & Chag/Yom Tov friendly: Quickly get the times for Candle Lighting and Havdala, then place the app on "Shabbat Mode" to keep the app running the whole Shabbat without any user-involvement.
- Personalize your Tefilot to the calendar-day, with our siddur. Includes the standard texts (Shacharit, Mincha, Arvit; also Mussaf & Selichot when relevant)
- Find the Tzadikim in our Hiloulot page. Pulled from all the different Jewish communities (Ashkenazi, Bukharian, Syrian, Iraqi,

All of the above is laid out in our calendar, filled with the weekly Parasha, hiloulot-listings & a siddur that changes its text depending on the day.

Each time is calculated according to our Mesora (described in-app by clicking the individual zeman), for all types of daily activities:
- Workers/Early-Risers Minyanim (Alot Hashachar/Dawn, Misheyakir - for Talit & Tefilin)
- Netz Shacharit, with a countdown for the Shaliach Tzibur and Visual Sunrise times pulled from ChaiTables.com
- Borderline Shacharit-time minyanim (Latest times for Shema - both MG"A & GR"A, Latest time for the Tefila/Berakhot Shema)
- Mincha times (Gedola for earlier, Ketana/Later for preferable)
- Early Arvit (Plag HaMincha - according to both Yalkut Yosef & Halacha Berura, Sunset, Nightfall - according to the Geonic tradition)
- Rabbenu Tam's Nightfall - applicable in stringent cases
