Your voice, your diary. Just tap and talk — and let the cat listen. 60 Sec Journal is the coziest voice memo diary for daily journaling. Record your thoughts in 60 seconds, no typing needed. Whether you call it a voice memo, audio diary, or voice journal, it's the simplest way to build a meaningful journaling habit — and now it comes with Miso, a hand-drawn cat who lives inside your journal. MEET MISO Miso sits with you on every screen. She perks up her ears and leans in while you record, hops with joy when you save an entry, and curls up for a nap once you're done for the day. Every recording comes with a soft purr you can actually feel through haptics. A FOREST THAT BREATHES Vines trail down from the top of every screen and sway gently. Spores drift up through the light — or fireflies, after dark. Toadstools grow along the bottom. It's a small, quiet world built to make journaling feel like sitting somewhere calm. KEY FEATURES 60-Second Voice Memo Entries Record your thoughts in just one minute. A gentle timer guides you so you can focus on what matters — your words. Mood Tracking Tag each entry with your mood — Great, Good, Neutral, Low, or Rough. Watch your emotional patterns unfold over time. Calendar Diary View See your entire month at a glance with color-coded mood indicators. Tap any day to replay your voice memo entries. Audio Playback with Waveform Listen back to your recordings with a beautiful waveform visualization. Speech-to-Text Transcription Every entry is transcribed so you can read your diary back anytime. Streaks See how many days in a row you've shown up for yourself. iCloud Sync Your voice diary travels with you, synced across all your Apple devices. Six Cozy Themes Moss Forest, Cream Puff, Peach Nap, Night Garden, Blossom and Misty Pine. Privacy First Lock your diary with Face ID or passcode. Your thoughts stay completely private. Full Accessibility Built with VoiceOver, Dynamic Type and Reduce Motion support from day one. 39 Languages Journal in your native language with full localization support. WHY 60 SEC JOURNAL? Most diaries go unused because writing feels like work. 60 Sec Journal removes that barrier entirely. A quick voice memo is all it takes — speaking is natural. One minute to capture how you feel, what happened, or what you're grateful for.
