Countdown, Event Reminder vs Myriadclock

Countdown helps you track the dates that matter most. Create one-time or repeating countdowns for birthdays, anniversaries, holidays, trips, weddings and other events. Repeat events daily, weekly, every two weeks, monthly or yearly. See the remaining time in years, months, days, hours or minutes, and get reminders before the big day. Browse your countdowns in Calendar View. Repeating events appear on each occurrence, and selecting a date shows everything scheduled for that day. Import birthdays from Contacts to create yearly birthday countdowns automatically. Previously imported birthdays are recognized, helping prevent duplicates. Customize each countdown with colors, icons and notes, reorder your list, share special events, and check upcoming dates from Home Screen widgets. Whether you are planning a vacation or remembering a special moment, Countdown keeps everything organized.

The open source ESP32 firmware can be found here on github (search for Myriadclock). Using this App the Myriadclock can be customized and configured using Bluetooth only. You can configure all colors, color modes, intensity etc.
