About this app

A journal you can actually keep up with.

Most journals ask for more than anyone has at the end of a day, so the habit dies in a fortnight. Linewell asks for one sentence — up to 280 characters. You can correct today or yesterday; after the next midnight, it becomes a permanent record rather than an endlessly edited draft.

WHY ONE LINE A DAY WORKS
• Thirty seconds a night is a habit you can keep for years
• The two-day writing window keeps the record honest without punishing typos
• A year of sentences reads back in about two minutes
• An unbroken-days count makes the habit quietly satisfying

WHAT'S IN THE APP
• Today: one sentence, editable today and the following day, locked after that
• History: every sentence, grouped by month, with your streak
• One daily reminder at a time you choose — free, not a paid extra
• Plain-text export of everything, saved to a folder you pick — free
• Set in real typefaces on six paper stocks, like a printed book

PRIVATE BY CONSTRUCTION
No account. No cloud. No sync. No ads. Your journal is a database on your phone and nowhere else — nothing leaves the device unless you export it yourself.

PREMIUM — A$7.99, ONCE
One small purchase, never a subscription:
• Five further paper stocks (Ink, Dusk, Moss, Rose, Noir)
• The Year Book — your year typeset as a PDF, made to be printed
• JSON backup and restore

Cheaper than the paper one-line-a-day books it replaces, and a fraction of a year of the big journaling subscriptions.

A five year diary, a micro journal, a gratitude journal, a memory keeper — whatever you call it, it is the smallest journal that still works.

Built by parkdeve in Australia. A real person answers support@parktechsystems.com.
One sentence a day. Private offline diary — no account, no cloud, no ads.
