Dayon — one shared calendar for the people who matter
Ever scrolled back through a month of chat messages just to find the plan you
made together? Dayon gives you and the people closest to you a single shared
calendar — plans, anniversaries, photos, and the small daily conversations,
all in one place.
■ A calendar you actually share
· Create a calendar for a couple, a group, or just yourself
· Invite with a 6-digit code or a share link
· Everyone gets a notification the moment a plan is added
· Weekly, monthly and yearly repeats
· Give each calendar its own color
■ D-Days and home screen widgets
· Track the day you met, birthdays and anniversaries
· The home screen widget counts the days for you every day — it stays correct
without ever opening the app
· A second widget shows what's on today
· Get a heads-up as milestones like day 100 approach
■ A photo timeline
· Keep your moments in the calendar they belong to
· Add a one-line note and comments to any photo
· See photos from all your calendars in a single timeline
■ Today's Question
· A new question arrives every day
· You answer first, then you get to see their answer
· Every exchange is saved, so you can read back through them any time
· A quiet reminder at 8 PM so it doesn't slip by
■ Time capsule letters
· Write to your future selves and choose the day it opens
· Until that day comes, not even they can read it
· Once sealed, a letter can't be edited — it stays exactly as you meant it
· You'll hear from us on the morning it opens
■ Shared memos
· Shopping lists, trip packing, things you want to do together
· Plain notes or checklists, whichever fits
· Any member can edit them and tick things off
· Pin the ones you check often to the top
■ Only the notifications you want
· Turn the daily question reminder, activity alerts and event alerts on or off
independently
■ Dayon Premium
· Remove all ads
· Unlock every widget theme
· Monthly Recap — your month in plans and photos
