MoodJournal - Encrypted Diary

MoodJournal is your private, encrypted daily mood diary -- beautifully designed for mental wellness tracking with military-grade security protecting every entry. YOUR MOOD, YOUR PRIVACY Every journal entry you write is encrypted with AES-256-GCM encryption before being saved to your device. Your encryption key is stored securely in the iOS Keychain and never leaves your device. Not even we can read your journal. This is real encryption -- not just a lock screen. FACE ID & TOUCH ID PROTECTION Secure your journal with biometric authentication. Every time you open MoodJournal, Face ID or Touch ID (with passcode fallback) ensures only you can access your private thoughts. MOOD TRACKING MADE SIMPLE Rate your mood daily on a 1-5 scale with expressive emoji faces. Add free-form journal text to capture what is driving your emotions. Tag entries with categories like work, family, health, social, exercise, or sleep to identify patterns over time. BEAUTIFUL MOOD CALENDAR See your emotional journey at a glance with the monthly calendar view. Each day lights up with a color-coded mood indicator -- warm purples for great days, soft grays for neutral days. Navigate months to review your history and tap any day to revisit that entry.
