Emerald Chronometer vs Geneva Moon

These models of high-end mechanical watch faces contain many of the most complex "complications" found in real watches, plus refinements found nowhere else. All displays maintain the look and feel of real mechanical objects, but with the time and location accuracy of the iPhone. NOTE: This app (Emerald Chronometer) is optimized for the iPhone and iPod touch. Please also see Emerald Chronometer HD, a separate product optimized for the iPad. Astronomy features: - Highly accurate data from 4000 BCE to 2800 CE - Times of rise and set for the Sun, the Moon, and the 5 classical planets - The correct shape and orientation of the Moon in all phases but still using a mechanical display - Relative positions of the Sun, Moon, 6 planets and the constellations of the zodiac - "Compass functions" show the elevation and azimuth of the Sun, the Moon, and the 5 planets - The Equation of Time, solar time and sidereal time - Eclipse predictor (lunar node indicators and separation indicator) - User settable geographic location and timezone using an 80,000 city database - A unique face showing the rise and set times of all 5 classical planets plus the Sun and the Moon at once Clock features: - Day/date/month/year indicators, using mechanical wheels - Local and UTC time - Chronograph (stopwatch) with split timer, 1/10 sec accuracy - Alarm clock and interval timer; notifications are delivered in iOS 4 if the app is not running** - World-time watch with 24-city ring on one side and 4 subdials on the other - Calendar watch with rotating wheels showing a full month at a time - Most watches with 1/5 sec or 1/10 sec precision - Synchronized with standard atomic clocks via NTP There are 16 watches in all, with 27 total watch faces (including front and back sides). A setting is available to allow the display to stay on only when plugged in. Play with the watches by tapping on the crown and moving the hands, or press and hold on a date window to zoom through time to see the effect on the heavens. Then just use them to show you when it's time for a break. A complete description of each application feature can be found in the built-in Help screens and on the Emerald Sequoia LLC Web Site, which also includes a demo movie. A developer's blog may also be found at http://emeraldsequoia.com/esblog/ . If you are having any trouble with the application whatsoever, please see our FAQ on the support page listed below and then contact us through that page if your problem is not resolved. We take pride in responding promptly to all support email requests. **NTP accuracy is not guaranteed for alarm delivery if the app is not running. (NTP requires Internet access. Like all apps Emerald Chronometer can not change the device's internal clock.)

I've always liked wearing a lunar complication on my Apple Watch. There is something both visually delightful but yet also slightly geeky about it. But I was unable to find a complication that provided an astronomically accurate moon display...which just kinda bothered me. So I made Geneva Moon. Geneva Moon seeks to provide a highly accurate, visually pleasing indication of what the moon looks like right now, right where you are. My goal was to make it so that if you look down at your wrist and then up into the sky the images you see should match. It includes a robust set of complications for every watch face type.   Choose between either a visually rich 'actual ' appearance or a more simplified version, to fit your own personal style. The main display indicates the current azimuth and elevation of the moon along the horizon along with a visual indication of its phase and orientation. Rotate the Digital Crown to shift forward and backwards through time and see how the moon will shift (tap on the screen to reset to now) On Apple Watches equipped with a compass (Series 5) you can have Geneva Moon orient itself towards the actual moon to make it easier to locate the moon in the sky. Thank you for considering Geneva Moon, I hope you enjoy having the moon on your wrist as much I do. —Dave
