The Siddur
סִדּוּרChoose your nusach
The nusach you daven. It is remembered, and you can change it at any time from inside the service.
Services
Pick a nusach above and the siddur opens at the service being said now — Shacharit in the morning, Mincha in the afternoon, Maariv in the evening. You can change it at any time, and your choice is remembered. Bentching and Havdalah are never opened for you: each is an occasion rather than an hour — a meal ending, Shabbos going out — and you reach them by tapping them. Where a service is missing in a nusach, the siddur says why rather than showing you a blank page. There is no Shabbat service in this siddur, and there will not be one.
