Every Kosher iPhone ships with the **KolBo Siddur** pre-installed. Not a link to a third-party app, not a demo version — a full, complete, multi-nusach siddur that works offline from the moment you unbox.
What's in it
Three nusachot
Ashkenaz, Sefard, and Edut HaMizrach. Pick yours — all three ship with the siddur.
Every tefila
Shacharit, mincha, maariv, tashlumin, musaf for chagim, all moadim.
Offline ready
No connection required. The full siddur is on-device.
Hebrew-Hebrew + translated
Pure Hebrew text or with English side-by-side. Your choice.
Auto-adjusting
Shows the right tefila for the right time. Adjusts for Rosh Chodesh, chagim, and aveilut.
Beautiful typography
Cream parchment background, serif Hebrew, easy on the eyes at 5 AM or 11 PM.
How it integrates with your Kosher iPhone
Because the siddur is pre-installed during configuration, you never have to download it, set it up, or choose a nusach on a small screen. It's ready with your nusach preference (set during onboarding) from the first power-on.
It also links into the broader KolBo ecosystem: tap "zmanim" inside the siddur to see your exact sof zman kriat shma. Tap "halacha" to see the Rema on any passuk. Tap "shiur" to hear a 3-minute audio explanation of any tefila from the KolBo shiurim library.
One app. One context. One frum life.
