You saved it for a reason. Nemos finds it when you need it. A link from a friend. A screenshot with a door code. A thought recorded on a walk. A PDF you meant to read. Nemos keeps them in one private library and gives them back the moment you search, so you never have to remember which app you used. FIND WHAT YOU SAVED One search runs across links, the text inside your screenshots, notes, voice transcripts and documents at once. Look for “boarding pass” and the screenshot surfaces, even though you never tagged or filed it. Search is in Spotlight too, so you can start from the Home Screen. SAVE FROM ANY APP Share to Nemos from Safari, Instagram, TikTok, Messages, Mail — anything with a share sheet. Links arrive with a real preview instead of a bare URL, and articles stay readable when you're offline. Nemos also keeps what you copy, so a code or an address from two hours ago is still there. SCREENSHOTS THAT COME BACK Every screenshot is read on your iPhone, so the words inside it become searchable. Keep screenshots in folders, or let smart folders sort them for you: everything from a trip, every receipt, every recipe. NOTES, DOCUMENTS AND FILES Write notes with images, links and checklists. Import PDFs, documents, spreadsheets and ebooks: they open without leaving the app and are searchable by what's inside them. Keep files in folders and tags, next to the notes they belong with. TASKS, TO-DOS AND ROUTINES Turn anything you save into a task with a reminder. Keep a to-do list with subtasks, then schedule, snooze and check off each item. Build routines for the things you do every day, with the steps, times and notifications you choose, and attach the recipe, note or screenshot a step needs. Reminders and routines appear on the Lock Screen and in the Dynamic Island while they run. EVERYDAY ORGANIZATION FOR ADHD If you have ADHD and want help keeping track of plans and saved information, Nemos keeps the next step and what it needs in one place. Capture the thought, choose when to come back to it, and find it again with one search. RECORD AND TRANSCRIBE Record a voice note and Nemos writes it down: on your iPhone, or in the cloud for long and multi-speaker recordings. Start from Control Center or your watch face and follow it in the Dynamic Island. PLACES Save a restaurant, a shop, a viewpoint. They land on a map, so “that coffee place near the park” is a glance instead of a scroll through old messages. ASK YOUR OWN LIBRARY Ask a question and Nemos answers from what you've saved, quoting the note, screenshot or link it came from. SHARE A FOLDER Invite someone into a folder and you both watch it fill up: a trip, a project, a reading list. You decide who can add and who can only look. ON IPHONE, IPAD AND APPLE WATCH Your library syncs through iCloud, so what you save on the phone is already on the iPad. One tap on the watch complication starts a voice note, and your next reminder and running routine sit beside it. Widgets, Shortcuts and Siri reach the rest. On a computer, the Nemos browser extension for Chrome, Safari and Firefox saves links and articles to the same library. PRIVATE BY DEFAULT Screenshot text recognition runs on your iPhone, and so does the writing model on devices that support it. Your library lives in your own iCloud account, not on our servers. The assistant only uses a cloud model if you turn that on. Long or multi-speaker recordings are transcribed in the cloud for accuracy, unless you turn on “Transcribe on this device” in Settings. NEMOS PRO Unlimited recording, unlimited active reminders, smart folders, more cloud transcription and the full assistant. Free keeps everything you save and opens your latest 50; Pro opens your whole library. The app shows plans, prices and any trial you're eligible for before you subscribe.

About

Estratum

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. CAPTURE WITH SIRI, TOO Save a note with Siri or Shortcuts without finding the app first. Text is saved before confirmation and organized when Estratum opens. Voice and dictation depend on Apple. YOUR DAY, IN ONE THREAD See appointments, tasks and dated items in a timeline centered on today. Move into the past or future and return to today when you need to. MORE ROOM, ON IPAD AND IPHONE DUO TOO On iPad and an open iPhone Duo, keep your timeline in view while writing. Notes shows list and detail together; Calendar pairs the month with your agenda. Close Duo to return to one column. When partially folded, content stays clear of the hinge. Draft text survives display changes. YOUR MEMORY CAN LIVE ON YOUR DEVICE 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. Local AI depends on device compatibility and memory. Below 6 GB RAM, Qwen is not offered; Apple's model appears only when available. Without a compatible local engine, you need to configure your own external-provider API key, subject to that provider's 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. On compatible systems and devices, Apple PCC is another optional cloud engine: it requires consent and internet, may send text and context to Apple, and has a quota separate from Pro. ESTRATUM REMEMBERS FOR YOU. PRO NOTICES, TOO. Free includes the same AI, every engine, unlimited saves, basic reminders and 7 questions per week. Estratum Pro adds unlimited questions, Knowledge Map, Diary, reminders that choose a useful lead time, and automatic Home/Work switching. Try it free for 14 days, then 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 device. With Pro, 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.
