Thanks for feedback Nikolay. We wanted to add many things. Notifications via SMS is for super busy people, who go offline from time to time but would never want to miss a reply from pg.

Also, we are considering adding a Telegram bot for notifications. Please let us know if someone would like this.

EDIT: I can't reply to posts below, so I am going to post here. The android notifications are default. On top of that we would like to offer other types of notifications: SMS, Email, Telegram bots, etc.
