Mono - One Sentence Journal

Mono is the calm home for your day. Write one sentence, watch your streak grow, and look back on a quiet record of small moments — synced across your devices.

Mono is a journal for people who don't journal.

One sentence a day. No prompts to fill, no pages to stare at, no streaks you feel guilty about. Just a quiet line for the moment you'd otherwise forget.

Minimalist by design — a single screen, a soft typeface, a 140-character canvas. Every detail is stripped back so the writing is the only thing left.

— One line a day, capped at 140 characters — Five basic moods: happy, calm, tired, sad, angry — Quiet streaks that encourage, never shame — Gentle writing prompts when you're stuck — Full iCloud sync across iPhone and iPad — free, forever — Dark mode, eight accent themes, New York serif hero

Mono Premium unlocks the reflective layer: — Year heatmap and written-month stats — Face ID app lock for private entries — Smart reminders that learn when you write — PDF export of any month — Mood tracking and 20+ writing prompts — Premium accent themes

Private by design. Your entries live on your device and in your personal iCloud. No account, no servers, no analytics, no ads. Ever.

One purchase. No subscriptions. No paywalls in the writing flow.

Made by one person in Istanbul. If Mono earns a corner of your day, that's the whole point.
