Tfilon is a free siddur that shows the prayers correct to the Hebrew date (Yaale Ve'Yavo on Rosh Chodesh, Al Ha'Nisim on Chanuka and Purim) without using the phone's internet.
All time and date calculations are done in the phone itself!
There is an option to show special things, such as Va'Anenu Bore Olam or a preyer for sick people, and you can select what day you celebrate Purim, and there's much more.
