Mahina

Moon phase viewer with a Hawaiian twist!  Accurately shows the current phase of the moon generated from a 3-D model of the earth-moon-sun geometry. Calculations are based on detailed equations that correctly take into account orbital characteristics such as inclination, distance, obliquity, nutation, libration, AND [optionally] the device's location on the surface of the Earth. Also generates relevant ephemeris data viewable on separate detail pages. Does not require a network connection; all calculations are performed locally within the app. Estimates the traditional Hawaiian lunar calendar day name based on calculated predictions for the astronomical full moon occurring near the beginning of the Hawaiian day Hoku. Traditional Hawaiian days ends at sunset, not midnight. * Allows two-finger pinch-zoom gesture. * Animate the phases of the moon over time by selecting "Animate" from the action menu; tap the animation to stop. Double-tap to reset back to current time, rotation, and zoom. The information icon in the lower-right corner brings up the action menu with multiple options. * Details page displays several moon ephemeris calculations for the given date and time. Items can be reordered and/or deleted from the list to prioritize which data items are displayed. Long-press on a value to copy to clipboard. * Motion sensors [if enabled] automatically rotate the moon image on the Phase tab to keep it in sync with what one might see in the sky. Enable Location Services for this feature to work. If Location Services are turned off, use the two-finger rotate gesture to manually rotate the moon image. * Lists upcoming phases with their dates and times on the Upcoming tab, and optionally displays alert notifications when they are about to occur. Identifies full moon at perigee as a "super moon." * Shows the phases of the moon for a full calendar year on the Calendar tab - swipe left and right to see other years. * Today widget quickly shows the current phase of the moon and the traditional Hawaiian day name on the lock screen or when the app's icon is Force Touched. If location information is available, will also show the parallactic angle, whether the moon is visible above the horizon, and next rise and set times. * iOS14 users can add new widgets to their home screen pages. These widgets display upcoming phase milestones, the current Hawaiian day name and fishing/planting hints, and/or the current month of moon phases in calendar form. Users in the southern hemisphere should go to the Settings app, scroll down to the Mahina settings, and set the "Hemisphere" setting to "Southern." The application will try to automatically set this value if location permission was granted, but it couldn't hurt to make sure. Two iOS permissions need to be granted for the app to utilize its full feature set. Location Services is needed to know when the moon rises and sets, and its orientation/rotation in the sky as seen from the device location. The app does
