Sediment
Read full descriptionHide full description
You found something worth remembering. A line from a book. A phrase in a new language. A thought you don't want to lose. Sediment keeps it visible - quietly rotating your fragments on your Lock Screen throughout the day. No flashcards. No quizzes. No notifications. Just your own words, surfacing when you glance at your phone. How it works: - Save fragments - quotes, vocabulary, notes, affirmations — anything worth remembering - Organize them into layers (e.g. "Spanish", "Stoic Quotes", "Exam Notes") - Sediment displays them as a Live Activity on your Lock Screen or Widget on your Home Screen, rotating on the rhythm you set - A passive spaced repetition algorithm decides what to show. Over time, fragments settle through three depths - Surface, Sinking, and Bedrock - so the words you know best surface more rarely. Once a week, on Foundation Day, your deepest fragments rise back to the top. Designed to disappear: Sediment follows the principles of Calm Technology. There are no nagging push notifications, no sounds, no badges. Nothing demands your attention. Your fragments simply appear and fade — like geological layers settling over time. Features: - Continuous Lock Screen Live Activity with progress bar and countdown - no schedules, no time windows - Home Screen and Lock Screen widgets - Strata: fragments settle through three depths over time, so the ones you know best surface more rarely - Foundation Day: a weekly day when your deepest fragments rise back to the top - Smart rotation powered by passive spaced repetition - Customizable rhythm: set how often your fragments rotate - Favorite fragments to boost their visibility and protect them from sinking - Quick Note: blazing-fast note taking directly from the Lock Screen - Full-text search across all fragments - JSON export and import - End-to-end encryption (AES-GCM) - your data stays yours - iCloud sync across all your devices - No account required. No servers. No tracking. Sediment Pro unlocks unlimited fragments. The free tier includes up to 10 fragments — enough to get started. Remembering starts with seeing. Sediment makes sure you do.
