About this app

My Diary - Private journal with lock for mood tracking, daily gratitude & self care.

Trusted by journalers ⭐

ZenDiary is an AI-powered journal that actually understands you. Write your thoughts, track your moods, and discover patterns in your emotions — all behind a secure lock.

🤖 AI COMPANION THAT LISTENS
Tired of basic diary apps that just store text? Apps like Day One and Daylio are great for writing — but ZenDiary writes back. Our AI reads your journal entries, notices emotional patterns, and gives you real insights. Like having a therapist in your pocket. No other mood tracker or gratitude journal does this.

🔐 PRIVATE & SECURE DIARY
Your secret diary stays secret. Password, PIN, or Biometric lock protects every entry. Google Drive backup keeps your memories safe. Export your daily journal to PDF, TXT, or images anytime. More secure than Reflectly, simpler than Journey.

🌈 MOOD TRACKING & EMOTIONAL INSIGHTS
The best mood tracker for understanding yourself. Log how you feel daily. See your emotional patterns over weeks and months. Unlike Daylio's basic charts, ZenDiary's AI tells you WHY you feel the way you do. Track gratitude, anxiety, happiness — everything.

📸 PHOTO DIARY & VOICE NOTES
More than a writing journal. Add photos, recordings, and videos to capture life's moments. Your digital diary becomes a visual journey. Perfect as a travel journal, pregnancy diary, or daily memory book.

✨ BEAUTIFUL MINIMALIST DESIGN
Clean, modern journal interface. No clutter like Diaro or other bloated diary apps. Just you and your thoughts. The personal diary experience you've been searching for.

📝 WRITE YOUR WAY
Use ZenDiary as a daily diary, gratitude journal, mental health journal, dream diary, or secret diary with lock. One app, endless possibilities. Whether you're switching from Day One, trying something better than Reflectly, or starting your first digital journal — ZenDiary grows with you.

Your thoughts deserve a safe home. Start your journaling journey today.

Hey, thanks a lot for the lovely review ❤️ That ribbon issue is a known bug — we’re already fixing it and it’ll be gone in the next update. “ZenDiary” is the original name of the app; “My Diary” is the store name. Really appreciate your support, it means a lot 🙌

From the very start I like this app but from here onwards I got attached to it because from the past I keep on writing my personal stuff in a diary but in diary anyone can look into it and this journal along with some modifications of my phone I can write whatever I want it's just perfect ,to be honest the bestest journal app . Whoever reading this please stop your Odyssey of finding journal app because you are the place where you want to be
