This uses the algorithms developed over the past 150 years along with the best information available about the locations of sun, moon, and earth to predict when an eclipse will occur at a particular location on the earth. In addition the prediction parameters are updated for the latest predictions by IERS. This is useful to find where to go, where to look, and how the moon will move across the sun.

Changes - I Ching Journal is a free I Ching reader and private journal. All content and features are included, with no in-app purchases or subscriptions. It is built around three actions: ask, read, and record. You can cast with the traditional coin method, read the primary and relating hexagrams, explore judgments and line texts, and keep your question, mood, notes, follow-up reflections, and revisit reminders in one private space. This is not a fortune-scoring app and it does not decide good or bad luck for you. It is closer to a portable classical reader and a private journal: a way to slow down a question, read the text carefully, and keep a record you can return to later. Features: - Coin casting and Dayan probability mode - Read all 64 hexagrams, judgments, line texts, Tuan, Xiang, and Wenyan for Qian and Kun - Explore primary, relating, nuclear, opposite, and inverse hexagrams - Journal entries, mood notes, follow-up reflections, revisit reminders, and an 8x8 hexagram map - Simplified Chinese, Traditional Chinese, and English interface - Original text, bilingual comparison, and translation reading modes - Face ID / device passcode privacy lock - Widgets, Live Activities, Shortcuts, and local notifications - Markdown / PDF export Journal entries are stored on device by default. If iCloud is enabled, sync uses the user's private CloudKit container.
