This is an Ashkenaz siddur (other nusachim available)
-Birkat Me'in Shelosh.
- Compass to tell you which way is misrach (East).
- Tefilin mirror, with lines to make sure your tefilin is straight.
- Auto scroll, you don't have to touch the screen the siddur will scroll by itself,(if you want).
Really easy, and simple to use.
