Even-LotH

Liturgy of the Hours app for Even Realities G2 smart glasses.

Displays the Divine Office prayers on the glasses as a smooth-scrolling teleprompter. Prayer text is sourced from divineoffice.org.

How it works

• A Node.js backend scrapes and parses prayer content from divineoffice.org
• A companion web app (Vite + TypeScript) runs on the phone and connects to the glasses via the Even Hub SDK
• Prayer text is pre-rendered onto an off-screen canvas and streamed to the glasses as image tiles for pixel-smooth scrolling
