Echo turns spoken thoughts into searchable notes. Tap once to record. Tap again to stop. Echo transcribes, summarizes, and pulls out the to-dos so you don't have to. Voice Memos saves audio. Echo saves the idea inside the audio — in English, Arabic, or both, switching mid-thought. WHAT ECHO DOES • Records up to two hours, with the screen locked or app backgrounded. • Transcribes on-device when it can; cloud transcription for longer or bilingual recordings. • Summarizes each note in a sentence or two. • Extracts action items with the dates and times you actually mentioned. • Lets you edit transcripts word-by-word, with audio linked to every word. • Sends action items to Reminders, events to Calendar — one tap. • Finds anything you've said by meaning, not just keywords. • Renders Arabic with proper right-to-left layout. Mixed-language transcripts render inline. WHY ECHO No filing, no folders, no streak shame, no productivity dashboards. Just a quieter place to think — and a way to find what you thought. PRIVACY IS THE BRAND Audio stays on your device whenever possible. When cloud transcription is needed — longer recordings, Arabic, mixed languages — your audio is sent over an encrypted connection to OpenAI Whisper or Anthropic Claude, and discarded after processing. Nothing is sold. Nothing is used to train models. Delete everything in one tap. ECHO PREMIUM • 7-day free trial, then $59.99/year — Family Sharing included. • Or $4.99/week, no trial. Subscription includes unlimited recordings, cloud transcription, semantic search across your whole library, Reminders/Calendar export, Live Activity, and the home/lock-screen widget. SUBSCRIPTION DISCLOSURE Echo offers auto-renewing subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. Manage or cancel any subscription in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
