Phenomenal, Still!
RustyBricks Siddur app has always stood head and shoulders over the crowd. Not just with its elegant presentation of the essentials, but also in the little touches that make it such a pleasure to use, even when there is a paper Siddur available.
At this point, I use it not only for the opening, but also to store and track essential al dates (birthdays, anniversaries, Yahrzeits), and zmanim throughout the day and week.
I know that Apples pace in approving updates has resulted in the program exhibiting minor bugs (i.e., the Tefillin mirror didnt work for a few days), but RustyBricks people jumped all over this relatively silly issue ... And their customer service people were great and responsive.
Kol hakovod!
