About this app

My secret diary with lock - mood tracker, gratitude journal & self care companion.
Loved by women who journal every day 🌸

ZenDiary is your private space to write, reflect, and feel better. A daily diary, mood tracker, and gratitude journal — all behind a secure lock only you can open.

🔐 PRIVATE DIARY WITH LOCK
Your secret diary stays secret. Protect every entry with a PIN, password, or fingerprint lock. Only you can open your journal. No one else — not even us — can read what you write. Safe, private, and yours alone.

🌸 MOOD TRACKER & EMOTIONAL INSIGHTS
The mood tracker that helps you understand yourself. Log how you feel each day with beautiful mood icons. See your emotional patterns across weeks and months in clear, simple charts. Spot what makes you happy, what triggers anxiety, and what brings you peace.

📔 GRATITUDE JOURNAL & DAILY REFLECTION
Build a daily gratitude habit in minutes. Write what you're thankful for, reflect on your day, and end every evening on a calm note. Perfect as a five minute journal, evening journal, or morning pages practice.

📸 PHOTO DIARY & VOICE NOTES
More than a writing journal. Add photos, voice recordings, and videos to capture every moment. Your digital diary becomes a beautiful visual story of your life. Use it as a travel journal, pregnancy diary, dream journal, or daily memory book.

This is pretty cool. I've never seen a journaling app before that gives book recommendations based on what you write about. My favorite features would definitely be mood momentum, happiness score, and best writing time & days. These are neat insights I've never seen in another app. My only complaint is that the actual typing of an entry makes my keyboard buggy, where it'll sometimes close on me for no reason, and I can only use full screen. The membership is definitely on my mind though.

Thanks so much for the thoughtful feedback The keyboard issue you mentioned definitely isn’t intended behavior. A few people have reported similar glitches with the editor, especially around full-screen mode, so we’re actively looking into stabilizing that experience. In the meantime, if you notice any pattern that would help us pinpoint it faster.
