The Koren Tefilla App, developed by Koren Publishers Jerusalem Ltd., is a versatile siddur available for iPhone users. This free app offers three different nusaḥim: Sefaradim (Edot Mizraḥ), Sefarad, and Ashkenaz, allowing users to choose their preferred prayer tradition.

Designed in accordance with the renowned design elements created by Eliyahu Koren, the siddur maintains the guidelines established by Koren Publishers over the past 60 years while adapting to the digital platform. The app automatically displays the appropriate tefillot based on the annual cycle and offers various tefilla modes, including davening with a minyan, ḥazzan mode, simḥa and aveilut, and geographic location.

Beyond the traditional prayer texts, the Koren Tefilla App provides additional content to enhance the prayer experience. Users can access audio preparations for Tefilla from different creators, commentary by Rabbi Jonathan Sacks, and a unique feature that displays the Tefilla word by word or sentence by sentence, promoting focused and immersive prayer.

With a range of settings and features, the Koren Tefilla App offers a comprehensive and interactive siddur experience on the iPhone. Explore the app to discover all its capabilities and provide feedback to the developers at
