Sediment – Memorize Quietly
Your words on your Lock Screen
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your words, quietly in view. Widgets show your full quotes again, and Sediment now follows your text size everywhere.
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 in view, quietly rotating your fragments on your Lock Screen throughout the day.
No flashcards. No quizzes. No notifications. Just your own words, showing up when you glance at your phone.
How it works:
• Save fragments: quotes, vocabulary, notes, affirmations, anything worth remembering
• Sort them into layers, like "Spanish", "Stoic Quotes" or "Exam Notes"
• Sediment shows them as a Live Activity on your Lock Screen or a widget on your Home Screen, rotating at the pace you choose
• A gentle spaced repetition algorithm decides what to show. Over time, fragments settle through three depths (Surface, Sinking and Bedrock), so the words you know best come up less often. Once a week, on Foundation Day, your deepest fragments rise back to the top.
Designed to disappear:
Sediment follows the principles of Calm Technology. No nagging notifications, no sounds, no badges. Nothing asks for your attention. Your fragments simply appear and fade, like layers of sediment settling over time.
Features:
• A Live Activity on your Lock Screen with a progress bar and countdown. No schedules, no time windows.
• Home Screen and Lock Screen widgets
• Made for iPad and foldables: your layers in a sidebar, your fragments right beside them
• Strata: fragments settle through three depths over time, so the ones you know best come up less often
• Foundation Day: once a week, your deepest fragments rise back to the top
• Smart rotation based on passive spaced repetition
• Your own rhythm: choose how often your fragments change
• Favorite a fragment to see it more often and keep it from sinking
• Quick Note: capture a fragment straight from the Lock Screen
• Search across all your fragments
• JSON export and import
• End-to-end encryption (AES-GCM), so your data stays yours
• iCloud sync across all your devices
• No account needed and no tracking. Your fragments are encrypted and only sync through your own iCloud.
Sediment Pro unlocks unlimited fragments. The free version holds up to 10, enough to get started.
Remembering starts with seeing. Sediment makes sure you do.
