About

SaiDay

Read full description

SaiDay is a diary that looks like a social media account. Post a photo or a few lines, and after a while characters drop by to like, comment and follow. Every one of them is a fictional character inside the app, each with a personality, a job and their own tastes. You are the only real person here; your diary is never shown to other users. No perfect persona to keep up, nobody to wonder about. Start from zero followers Your first follower, first comment and every milestone arrive slowly, with quiet weeks and unfollows too. A dashboard shows your simulated follower curve and how each post did. Comments that read what you wrote Characters comment on your category, place and mood. On a supported Apple Intelligence iPhone (iOS 26 or later), SaiDay also reads the gist of your caption on the device so a few characters can mention what you wrote. Free, and you can turn it off. Nothing goes to an outside AI service; comments are still picked from built-in, reviewed sentences. Gentle when it matters When you write about something painful, the trolls stay away and only kind comments come, with a quiet note on where to find help in your region. Friends can comment too Make a name card and share the link. A friend taps it to add you, and you become a "twin" in their diary that comments the way you type. A short typing quiz also tells you which of eight bubbles you are. You cannot see each other's diaries. Sharing stores the card for 30 days so the link works; you can stop sharing at any time. Look back A monthly recap card at the start of each month, plus calendar, On This Day, map and highlights. Home Screen widgets show memories. Yours to keep Lock your diary with Face ID, Touch ID or your passcode. Up to 10 photos per post, unlimited highlights, share cards, full backup and restore, and text and PDF export are all free. Themes Plain White, Plain Black, Paper Journal and Matcha are free. Plus and Pro add four more themes and six app icons. SaiDay Plus and Pro, one-time purchases Free: up to 5 custom characters. Plus: four more themes and six app icons, up to 20 custom characters (twins and regulars count), faster and more simulated responses, a blue badge, and 15 promotions a month. Pro: everything in Plus, unlimited custom characters, a gold badge, 4-hour promotions and unlimited promotions. Plus owners can upgrade to Pro for the difference. Restore Purchases is in the app. No monthly fee. Everyone gets one free promotion a day. Plus also refills 15 promotions a month from your purchase date, which do not roll over; a 10-pack can be bought and never expires. Prices are shown on the Apple purchase screen. Your diary, your call No account, no ads, no tracking, and the developer never receives your diary. The only things stored on the developer's service are a name card you choose to share (kept 30 days) and a public version check. Deleting the app or resetting erases the diary on the device, so keep a backup. Followers, likes, comments and reach are fictional characters and simulated numbers, unrelated to any real social network. Purchases do not add real followers or exposure.
