Description by Klaus Siebeneicher(from the App Store)
Echo is a private voice diary - built for people who want to journal every day but hate typing. Speak your thoughts, capture your day, and keep a personal audio journal that lives entirely on your device.
No account. No cloud. No compromise on privacy.
SPEAK, DON'T TYPE Recording a diary entry takes less than ten seconds. Open Echo, tap record, speak freely. Your voice memo is saved instantly as a private diary entry - timestamped, organised by date, and ready to replay whenever you want.
OFFLINE AI TRANSCRIPTION Echo converts your voice recordings to text using on-device AI. No audio ever leaves your phone. No internet required. Your words stay with you. Choose from three quality levels - Low, Medium, or High - depending on the storage you can spare.
A CALENDAR BUILT FOR YOUR MEMORIES Every entry lives on your personal calendar. Jump back to any day, week, or month and relive your thoughts exactly as you recorded them. Echo also surfaces past entries from the same date in previous years - your own "this day in history."
CATEGORIES & COLOUR CODING Create custom categories - Work, Family, Travel, Health, Ideas, Mood - and colour-code every entry. Your calendar fills with colour as your diary grows. Filter any category to find the right moment in seconds.
PRIVACY FIRST - ALWAYS - Everything stored on your device only - Optional PIN lock for extra security - No account, no sign-up, no login - No ads, no tracking, no analytics - Full GDPR compliance - Your voice recordings never leave your phone
DAILY REMINDER Set a personalised reminder at any time of day. Echo will nudge you to record your thoughts - so building a daily journaling habit becomes effortless.
LOCK ENTRIES UNTIL A DATE Write yourself a message for the future. Lock a diary entry until a specific date and rediscover it when the time comes.
BEAUTIFUL & MINIMAL DESIGN Echo is designed with a clean, distraction-free interface. Full dark mode, light mode, and automatic system theme support. Set your display name and make Echo feel personal from day one.
WHY ECHO? Most diary and journal apps require an account and sync your private thoughts to a cloud server you don't control. Echo doesn't. There is no account to create, no server to trust, and no subscription to pay. Your voice, your words, your memories - they exist only on your device, and nowhere else.
Echo is not just a voice recorder. It is a private, personal audio journal built for everyday life - quiet, honest, and completely yours.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
