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

With the Calendar Timeline App for watchOS you'll get a nice overview of the calendar entries within the next seven days – also reminder for today and earlier are supported in one single app. The app comes with a set of complications – also with a nice big complication for Modular Duo and Infograph Modular watch faces. In this complication you'll see all events and reminder of the day and got the next one display above. HUGE Update: Now you can choose your favorite style! · Fixed timeline: Fixed timespan from 6 am to 12 am · Dynamic timeline: The timeline shows the timespan from first to last event of the day with 1 hour padding each side · Dynamic timeline with actual time: Like dynamic but with the actual time marker (if before first or past last event) · Moving timeline: You will see a 4 hour timespan for the future and the timeline is moving through the day (only style where the next day do not get shown when after 6 pm and past the last event) · Also you can choose if you like the full big image on your watch face or like the next event text and actual date on top of the timeline. · You can switch on text in timeline which (mostly) fully displays your event text. · Even add you favorite tint color. With these settings you can configure your own style on your own watch face! ** IMPORTANT NOTE ** The big graph complication / widget only runs with Apple Watch Series 4 and higher (high detail watch faces like Modular Duo, Infograph Modular or Infograph Compact watch faces). MDM (company) managed devices may do not provide calendar data even when granted access since watchOS only apps cannot read MDM profiles. Since watchOS 10 the Complication maybe need some time to refresh to new settings due to Apples refresh policy. ** CANNOT RE-DOWNLOAD THE APP? ** For watchOS only apps you need to open AppStore on your watch itself and search for calendar timeline to re-download the app. Sorry for that, but that's Apples flow for watchOS only apps.
