This audio Siddur app teaches you how to daven in Hebrew by hearing the words pronounced. It goes through the standard Ashkenazi Shabbat prayer service, both Shacharis (the morning service) and Mussaf (the additional morning service for Shabbat).
* Select a text to learn from the table of contents
* Touch a word to hear it pronounced
* Click the play button to hear the full text read aloud
* Touch a word to jump forward or backward in the text
This app was borne out of my desire and inability to pray in Hebrew. I hope you find it helpful.
