LESS NOISE IN YOUR HEAD. MORE CLARITY IN YOUR DAY. How much energy do you spend trying not to forget an appointment, an idea, a task or a small detail you may need later? Estratum reduces that mental load. Write down what is on your mind and get back to your day: it saves it, organizes it and helps you find it when it matters again. CAPTURE BEFORE IT SLIPS AWAY Write, dictate or photograph a printed appointment, a receipt, a whiteboard or a set of instructions. No folders, categories or tags to prepare. Organization happens afterwards. AI DOES THE INVISIBLE WORK Estratum recognizes notes, tasks, appointments, deadlines, expenses, ideas and memories. You capture the moment; the app brings order to it. Search by meaning retrieves the context even when you do not repeat the exact words you wrote. Ask “What did we decide about Atlas?” or “What do I have tomorrow?” and open the notes behind the answer. TODAY AND TOMORROW, AT A GLANCE The intelligent TODAY section brings together appointments, tasks and dated items from Home and Work, so you do not start by checking separate notes, calendars and lists. Swipe to prepare TOMORROW and use the calendar to see everything ahead. YOUR MEMORY CAN LIVE ON YOUR IPHONE With a local engine, Estratum organizes, searches and answers on-device. After the initial download it can work without internet: your notes are not sent to a server, no account is required, and there are no token or query fees. If you prefer an external provider, connect your own OpenAI or OpenRouter key. The app warns you before sending the required context to the provider you choose. FREE THINKS THE SAME. PRO THINKS MORE ABOUT YOU. Free includes the same AI, every engine, unlimited saves, basic reminders and 15 questions per week. Estratum Pro adds unlimited questions, Knowledge Map, Journal, reminders that choose a useful lead time, and automatic Home/Work switching. Unlock it with one purchase—no subscription or recurring fee. Designed for people with ADHD, neurodivergent minds and anyone living with a high mental load. Estratum does not diagnose or treat any condition. YOUR LIFE IS YOURS The main database lives on your iPhone. Apple Calendar integration is optional and writes to a separate calendar. No ads. No selling your data. Write it down. Estratum takes care of the order.
