Struggling to stay focused? TiniAid helps your brain settle into productivity using adaptive sound environments designed for people with ADHD and other neurodivergent minds. Instead of forcing you to be productive, TiniAid creates the right soundscape so your mind can naturally focus. While most focus apps play casual background music, white noise or is just a fancy "Timer", TiniAid is built specifically to support attention regulation, helping you cancel the noise from your mind. Built for ADHD and Neurodivergent Minds - TiniAid’s sound environments are inspired by research on auditory stimulation and attention regulation. Studies suggest that certain types of music and sound patterns can support focus for people with ADHD by helping regulate stimulation levels. Layer Your Sound Environment - Combine amplitude modulation, beats and other music layers to create a personalized soundscape. You choose your stimulation! Study and Productivity Sessions Use structured focus sessions to build better productivity habits and maintain momentum. Distraction-Free Design A minimal interface keeps your attention on your work, not the app. Perfect For • ADHD focus support • studying and exam preparation • deep work and productivity • reading and writing • creative flow • distraction-free concentration Focus becomes easier when your environment supports it. TiniAid helps you create the sound environment your brain needs to stay in the zone.

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.
