Create separate timelines for different parts of your life and keep everything clear, intentional, and personal. On This Day Some memories deserve to resurface quietly. Oneline shows you what you wrote on this day in previous years, without notifications, pressure, or nostalgia traps. Privacy-first • No accounts required • Data stored locally or in your personal iCloud • No tracking • No ads • No social features Your timeline belongs to you.

Latest release
What’s New
Some days need more than a line. Oneline can now keep a whole note behind one. • Turn on Long-Form Notes in Settings to write a longer note under any line. The line is still the entry, and the timeline looks exactly as it did, with a small mark on the days that have more behind them. • Give the text shape as you write it, with bold, italic, headings, lists and quotes. It styles itself on screen while you type. • Dictate straight into a note. The words land where your cursor is, so you can talk into the middle of a paragraph you already started. • Search now looks inside your notes, not only your lines. • Notes travel with your exports, in Markdown, JSON and CSV alike.
