Whisper Memos is an AI voice-recording app for iPhone and Apple Watch, created by independent developer Vojtech Rinik, that records spoken memos and delivers them back as nicely formatted email transcripts within seconds. You can start a recording from a one-tap iPhone lock-screen widget or hands-free from an Apple Watch complication, making it suited to quick capture of rambling thoughts, meeting notes, lectures, or journal entries. Under the hood it offers multiple transcription engines, including OpenAI Whisper, ElevenLabs, and Cohere, and supports many languages with automatic paragraphing. Every voice note can get an automatic AI summary, and you can create custom summary tabs with your own prompts, for example to extract action items from meeting notes or to reorganize thoughts by topic. The app supports importing audio files in formats such as MP3, M4A, WAV, AAC, and FLAC. An Agents system routes different memos to different destinations, and integrations cover Notion, Trello, Things 3, Todoist, Day One, Evernote, Reflect, and Drafts, plus thousands more via Zapier or Mail Drop. It markets itself explicitly as a dictaphone, an audio recorder for meetings, and a voice journaling app, and has been covered by outlets like Six Colors and MacSparky. Pricing varies by plan.
