Your head is full. This gets things out of it. Brain Dump is built on one idea: capturing a thought should cost nothing. No folders to choose, no category to pick, no form to fill in. Open the app, type the thing, done. Structure comes later — or never, if you don't need it. CAPTURE IN ONE TAP The capture bar sits at the top of the screen, always ready. Type a thought and it's saved. Add #tags as you write and they become filters automatically. SORT IT LATER, IN SECONDS Thoughts you capture quickly land in Triage. One tap files each one as an idea, task, note, question or inspiration. A week's backlog clears in under a minute. FIND ANYTHING Full-text search across everything you've written, including answers and tags. Filter by status, sort by date or priority, pin what matters to the top. SWIPE TO CLEAR Swipe right to complete, left to delete — with undo, so a mistake costs you nothing. Long-press for edit, duplicate, share and pin. YOURS, AND ONLY YOURS Everything stays on your device. No account, no sign-in, no cloud sync of your private thoughts. Export the whole lot to JSON or CSV any time, and restore it just as easily. — BRAIN DUMP PRO — Free covers capture completely. Pro is for what the app can work out from what you've written: ECHOES The thought you've had five times without noticing. Brain Dump spots thoughts you've written more than once, even in different words, and shows you how long you've been circling. OPEN LOOPS Questions you asked yourself and never answered. Urgent things quietly going stale. Surfaced before they rot. YOUR PATTERNS When your head is clearest, what you keep returning to, how long things take you to finish — and whether marking something urgent actually makes you do it faster. WEEKLY REVIEW Your week in fifteen seconds: what you captured, what you closed, what's still open, and one thing worth a look. ON THIS DAY Old thoughts come back when they're useful again, instead of when you go digging. Plus photo attachments, per-thought reminders, and custom categories. — WHAT STAYS FREE, FOREVER — • Unlimited capture • All six categories and priorities • Your full history, always searchable • Tags, pinning and daily reminders • Export everything, any time We don't lock you out of your own writing. Pro buys you what the app does for you, never access to what you wrote. Pro is available monthly or yearly with a free trial. Cancel any time.

Yemma 4 is a private AI chat app that runs entirely on your iPhone. It runs Google's Gemma 4 locally through a Swift-native MLX multimodal runtime, so your prompts, images, and responses stay on your device. There is no account to create, no cloud inference service in the middle of your conversations, and no telemetry pipeline watching what you do. Download the model once, then keep chatting on Wi-Fi, cellular, or in airplane mode. Ask questions, brainstorm ideas, rewrite text, summarize notes, describe photos, and have real back-and-forth conversations with image attachments, all processed on-device. Why Yemma 4 feels different: - 100% on-device AI chat - No sign-up, login, or subscription - Offline after the initial model download - Local conversation history you can delete any time - Adjustable response style and creativity controls - Image understanding through the same on-device model Hardware note: - Requires iPhone hardware with the A17 Pro chip or later - First model download is about 4.2 GB, so Wi-Fi and free storage are recommended
