What is the Smart Siddur application, how does it work?

According to the introduction of Karri Apps, Smart Siddur is a Books & Reference app on the Android platform. There is currently a 7.2.226 version released on Mar 27, 2020, you can see the details below.

A full smart Siddur prayer book that packs everything you need exactly at the time you need it.

This Siddur app gives you a Jewish prayer book in all main Nusachim including Edot Mizrach (Sfaradim), Ashkenaz, Sfarad (Sfard, Chasidim, Union Nusach) and Chabad (Ari, Tehilat Hashem).

The Smart Siddur automatically organize the prayers to perfectly fit the current Hebrew date. So for example on Rosh Hodesh you will see Halel after Amida, but on a regular weekday, you'll see Tahnun.
A celebration in Shul? Does someone have a new baby boy? You can simply toggle the No Tahnun option and immediately it will be removed from the text.
