How the library works on your Kosher iPhone
**Offline-ready**: every sefer can be downloaded for flight-mode learning. The full library is ~800 MB — a fraction of your phone's storage.
**Cross-references**: tap any passuk or gemara and see every commentary linked to it. Tap any Rambam and jump to the Raavad.
**Search in Hebrew or English**: find every instance of a word or phrase across the library.
**Bookmarks + notes**: save chavrusa progress, add chiddushim, export to PDF.
**Integrated with shiurim**: if a speaker in the shiurim library discusses a specific sugya, tap through to the gemara text.
Why this pairs with the kosher iPhone
A frum phone without a digital library is a missed opportunity. Most kosher-phone customers want Torah content accessible — but configuring Sefaria or buying sefarim app subscriptions separately is friction.
**We solve it by default.** When you buy a Kosher iPhone, the library is already there, signed in, ready to open.
