Hyper iOS App: Voice Recorder with Real-Time Transcription and Action Extraction

Hyper is an iOS app that functions as a voice recorder specifically for spontaneous, unstructured conversations. The developers built it after experiencing at a robotics startup that important decisions often happened in informal settings like hallways, lunches, or walks, and weren't captured by traditional meeting tools designed for scheduled Zoom calls.
How It Works
The app requires iOS 26.0 or later, is 33.3 MB in size, and is free to start with an in-app subscription called "Hyper Believer" for $14.99/month. You sign up with just your phone number.
Core functionality:
- One-tap recording: Start recording any conversation (1:1s, coffee chats, standups, whiteboard sessions, study sessions) with a single tap. No setup, workspaces, or folders required.
- Real-time transcription: Conversations are transcribed as they happen.
- On-device wakeword detection: Say "hey hyper" mid-conversation to ask questions without breaking flow (e.g., "What did we decide about the deadline last time?"). The app pulls answers from all past conversations it has recorded.
- Post-conversation processing: After the meeting, an agent extracts structured actions and maps them to tools like Calendar, Gmail, and native iOS integrations. You receive a summary, full transcript, and tappable action items (calendar events, reminders, email drafts).
- Correction feature: If something in the notes is off, you can tell Hyper what to change via voice command.
- Search and tracking: All conversations are searchable, and action items are tracked.
- Weekly recap: At the end of the week, Hyper sends a highlight reel showing metrics like number of conversations, total minutes recorded, and frequently used words.
Technical and Privacy Details
The app's privacy practices, as stated by the developer Shalin Shah, involve data linked to your identity for app functionality. This includes:
- Contact Info (Phone Number)
- User Content (Audio Data)
The developer is building a long-term memory framework intended to let Hyper resolve conflicting information, surface stale details, and help untangle complex problems. The vision is a system where users can ask questions across all their conversations and get instant answers without manual file organization.
