Strata: Layered Journal

Strata is a journal for thoughts that aren't finished yet. Most journals expect a complete entry. Strata doesn't. Write a line when something strikes you, then come back later and add another layer to the same moment — a day later, a month later, whenever the thought develops. Over time an entry becomes a record of how your thinking changed, not just what you thought once. PRIVATE BY DESIGN Everything stays on your device. There is no account, no server, and no sync. Strata contains no analytics, no tracking, and no advertising. Your writing is not readable by anyone but you, because it never leaves your phone. WRITE IN LAYERS Start with a moment. Add layers as the thought grows. Each layer is timestamped, so you can see the shape of your own thinking over weeks and months. FIND YOUR WAY BACK Browse your history, filter by tag, or let Discover surface older entries you'd forgotten writing. KEEP WHAT MATTERS Export any entry as a PDF or a shareable card. Create an encrypted backup with a passphrase only you know. LOCKED IF YOU WANT IT Turn on App Lock to require Face ID, Touch ID, or your passcode before Strata opens. Strata works entirely offline. It always will.
