No journaling, no long prompts — just a quick pulse check you can do on the train, after a meeting, or before bed. Check in from your home screen widget or ask Siri without opening the app. AI PATTERN ANALYSIS MoodThread is the only mood tracker that connects the dots across your entire history. It finds which days you consistently dip, what triggers your best moods, and how your emotional patterns shift over weeks and months. The longer you use it, the smarter it gets. SMART NUDGES Get a gentle alert when something shifts — like tagging "Anxious" three days in a row, or your mood dropping compared to last week. No spam. Just the moments that matter. EMOTION LIBRARY Every emotion you tag builds a personal dictionary — how often it appears, what triggers it, which other emotions it shows up with, and what it means for you specifically. Not a generic definition. Your patterns, your insights. TRIGGER INSIGHTS See exactly how Work, Sleep, Exercise, Relationships, and other context tags impact your mood. Know which triggers lift you up and which bring you down. WEEKLY MOOD DIGEST Every Monday, get a personalized summary of your week — dominant mood, trending emotions, strongest triggers, and a reflection prompt. YOUR EMOTIONAL CALENDAR Color-coded calendar shows your mood at a glance. Spot patterns between weekdays and weekends, busy weeks and quiet ones. Track your check-in streak without pressure.
