About

Couples Diary

Features
Read full description

You do not have to talk a lot every day. One line a day is something you can keep up. Couples Diary is a quiet shared diary for a partner or a spouse. [One line a day, exchanged] - You each write your line for the day - Only on a day when both of you have written does the other person's line open (writing first never puts pressure on the other) - Lines you have written can be read back quietly, later [Remember the days that matter] - Register the day you met, an anniversary, anything - A quiet word the day before - There is no limit on how many anniversaries you keep [Designed never to nudge or compare] - No reminder notifications sent to the other person - No read receipts, and no "typing" indicator [Free, with one optional purchase] - The app itself is free. Exchanging lines, anniversaries and reminders, backup export and import, text export of your record, and text size and sound settings are all free - A one-time in-app purchase (paid once, not a subscription) unlocks exporting your shared record as a PDF. The price is shown in the app before you buy, and everything above keeps working without it [Made to be safe to use] - No ads - Your line and your anniversaries travel through a server that connects the two of you, and reach only each other (no photos, no location) - No names and no accounts. All that connects you is a shared phrase Not many words. Just one a day, between the two of you. Developed by SAKURA PRODUCTS
