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

Your calendar manages your schedule. Annidiem remembers the days for you. If you think you're a bit ahead of the curve, this one's for you. Birthdays, anniversaries, exams, trips, moving into a new home, a family reunion — the days that matter deserve better than a crowded calendar. Some are still ahead of you. Some already happened. Either way, they deserve somewhere to stay. Flip the bottom-right corner of a card and it turns over into that day's own record. You don't have to wait for the day itself — write while you're looking forward to it, while you miss it, or the moment it crosses your mind: photos, thoughts, voice memos, short videos, each one stamped with the place and weather of that moment. No folders to create, no "where should this photo go" — it belongs to a day, so it stays with that day. If you remember which day it was, you'll find it again. And when the same day comes round again, every year keeps its own: this year never mixes with last. When a day is no longer in focus, put it away — not throw it out. It leaves your home screen and stops reminding you, while the diary and photos stay, ready to bring back. Life gets simpler.
