Saidam - Couple Diary & D-Day

Saidam is a private space for two people. A room always holds just the two of you, and you can keep a separate room for each person.

Count the days you have shared, send letters that arrive later, draw on the same page at the same time, and keep your photos, moods and plans in one place.

For partners, or for your closest friend.

EXACTLY TWO One invite code, one person. No third member. No public feed, no followers, no strangers. One room with a partner and up to five with friends. Rooms never see each other.

DAYS TOGETHER Pick your start date and Saidam counts the days and the next anniversary for you.

CHAT Photos, voice notes and stickers. Type (love) in a sentence and the picture appears there.

LETTERS Write by hand or with your voice. Choose a day for it to arrive.

SHARED CANVAS Draw together in real time and watch each other's strokes appear.

ALSO Photo album, praise notes, shared calendar, places to revisit, links to watch together, recipes, home screen widgets, Face ID lock.

OUR PROMISE No ads. We never sell your records or use them to train AI. You can download everything at any time. The app and every feature are free. One sticker pack is available as an optional purchase.
