One Line in Time is a journal for people who find Day One exhausting. One text field, one date, nothing else. No photos, no tags, no mood picker, no prompts, no AI. After a year, your entries render as a printable paperback. Made quietly by sthreelabs.

One Line in Time is a deliberately constrained daily journal. A single text field for today, then tomorrow another one. No photos, no tags, no mood picker, no AI prompts. Browse entries by date or calendar; full-text search across everything you've written. Export any range as a paginated PDF styled like a paperback — a real keepsake from a quiet habit. Paid once at $2.99.
Most journaling apps grow features to encourage retention — moods, weather auto-capture, photo attachments, AI reflection prompts, voice notes. One Line in Time goes the other way: a single text field per day, with an explicit no-scaling rule. The entire app fits in a single sentence: write one line today; come back tomorrow.
The constraint is the design. A blank-page journal asks "what should I write?" and the answer can sprawl. A one-line field forces compression — what mattered today, in one sentence — which is the kind of journaling habit that actually survives multiple years.
Browse entries via a chronological feed or a calendar grid. Full-text search across everything you've ever written. The signature feature is the export: at any point, you can render a date range as a paginated PDF styled like an actual paperback book — same Crimson Pro typography, same warm cream paper, same hand-set feel as the rest of the sthreelabs collection. After a year, you have a real keepsake.
It's part of the small paperback family of apps under the sthreelabs label, alongside Tallies (habit counter), A Spell of Work (focus timer), and A Deep Breath (breathing paired with public-domain literature).

One Line in Time (and all sthreelabs marketing) uses the paperback design language. If you'd like to color-match in editorial graphics:
Typography: Crimson Pro (300–600 weights, italics) for body and headings. JetBrains Mono 400 for numerals and small caps.
Lines from the listing copy that are designed to drop cleanly into editorial.
