How to say the bedtime Shema
Before sleep, read the bedtime Shema in the siddur order. There is a dedicated page for reading on your phone. The order includes the Shema and related passages according to the nusach. It is easy to read from your phone by the bed, without a printed siddur. The public page opens without choosing a community.
Does it replace Maariv?
No. It is a separate reading before sleep.
