An Siddur application that distinguishes it from the rest of the Siddur applications is that it has the "form of the page" so that the worshipers will have a sense of prayer rather than reading an article.
In addition - the app displays the prayers that are relevant to the time of the day on the main screen and matches them to the date, so that on the first of the month it will also presented Halel and Musaff, and will remind you to say Yale ve'Yavo, etc.
