Capture a thought by voice. Find it later. Free iCloud sync, optional one-time upgrades, and your choice of local storage or your own AI backend. Save a thought while you walk. Find a decision after a meeting. SecondBrain Pro is a voice-first memory app for iPhone and iPad, with an Apple Watch companion for capture from your wrist. Choose local storage or free iCloud sync. Optional Standard and Premium upgrades are one-time purchases. CAPTURE AND RECALL Record a thought or type a note. Organize ideas, learnings, tasks and decisions with tags. Search saved memories by text and dates, or ask AI Chat about your memories when a supported AI provider is available. START FREE Voice and text capture, ordinary search, local storage and iCloud sync are included in Free. On-device AI chat is available on supported Apple Intelligence devices. No SecondBrain account is required. iCloud needs your Apple account and available iCloud storage. STANDARD: OPTIONAL ONE-TIME UPGRADE Add premium speech playback voices, expanded memory context, JSON/Markdown export, and backup and restore tools. iCloud sync is already included in Free. PREMIUM: YOUR OWN BACKEND AND MCP Includes Standard capabilities and adds a connection to your own Cloudflare Worker backend, backend semantic search, API access and MCP integration for compatible tools such as Claude Code and Cursor. This option requires your own Cloudflare account, deployed backend URL and API key. MCP also requires a bridge and compatible client. Cloudflare usage may incur separate charges. Local-only memories are not automatically available to external assistants. WHERE YOUR DATA GOES Local Only stores memories on this device. iCloud sync transfers them through your personal Apple iCloud account. The optional Cloudflare mode sends memories to your configured backend for storage and selected AI processing. Connected MCP clients handle data according to their own configuration and provider policies. Voice capture uses Apple's speech recognition and may use Apple servers. Microphone and speech recognition permission are required. Location context is optional. The app requests in-app consent for AI processing. AI REQUIREMENTS On-device AI chat uses Apple Foundation Models and requires iOS 26 or later, compatible Apple Intelligence hardware, Apple Intelligence enabled and an available model. Voice capture and ordinary search do not depend on Foundation Models. Premium users can configure cloud AI through their own backend. Check the App Store compatibility section before installing. PRICING Free download. Standard and Premium are optional one-time in-app purchases, with no SecondBrain subscription. See the purchase sheet for your regional price and currency. External backend services are separate. Developed in Switzerland by Heinrich Krupp. Product facts: https://secondbrain-pro.netlify.app/facts Support: https://secondbrain-pro.netlify.app/support

More reliable saving of your memories: - Shared content (Share menu) is no longer lost when you are offline or not using your own backend. It appears the next time you open the app. - Memories that could not be sent to your own backend are retried automatically. - If the database cannot be opened, the app now tells you clearly instead of accepting entries that would be lost later. - Purchases, Ask to Buy approvals and refunds are applied right at launch.
