Product snapshot
EZ Celestial Navigation is a navigation application created by EZ Celestial LLC that brings traditional celestial techniques into a modern, easy-to-use app. Designed for novice learners and experienced mariners alike, it streamlines the steps needed to determine position using astronomical observations while preserving the underlying nautical methods.
Supported platforms
The app runs on current Apple hardware: iPhone, iPad, iPod touch, and MacBooks equipped with Apple Silicon (M1 and newer). Interfaces are optimized for touch on mobile devices and for keyboard/trackpad use on Macs.
Core capabilities
- Direct access to tables from the Nautical Almanac and Pub. 229 presented in a clear, searchable layout
- Ability to output and print Nautical Almanac pages and related reference material
- Options for fully manual sight reduction or assisted, automated calculations depending on user preference
- Tools to store, organize, and archive observation records for later review
- Functionality to record bearing and sight observations with timestamps and metadata
- Guided workflows that walk users through each step to produce repeatable, accurate results
Educational and training value
Instructors find the application useful because it bridges classroom exercises and real-world practice. Lessons can combine hands-on sight-taking with the app’s step-by-step procedures, allowing students to learn classical techniques while checking their work with digital tools.
Additional notes and alternatives
Although focused on celestial navigation, the app’s documentation also points users to other maritime and travel utilities when appropriate. For unrelated travel tasks, some users consult third-party booking and PNR apps such as Trainman (a free train booking/PNR service), but these serve different needs than EZ Celestial Navigation.
