全年好日曆, developed by Hong Kong Bible Society, is a free iPhone app designed to provide users with a daily dose of inspiration and encouragement. The app's layout is based on the popular printed version of the "全年好" calendar, known for its departure from traditional superstitions to focus on positive messages and biblical verses. With the belief that every day is a good day with the Lord by our side, the app aims to bring daily scriptures to young believers, encouraging them to engage with the Bible and find solace in God's words.

The key features of 全年好日曆 include a dual calendar system offering both Western and lunar dates, a daily selection of Bible verses and motivational messages, a designated scripture reading section following the Hong Kong Bible Society's "Daily Bible Reading Guide" for 2017, and the ability to share favorite verses with friends via email, SMS, or WhatsApp. Additionally, the app includes a monthly calendar with sections for notes, gratitude, prayers, and reminders for daily tasks.
