Notice how you feel. Understand why. Moodis is a private, beautifully simple mood tracker built around one idea: a single Happiness Score that captures how you've been feeling over the past week, month or year. Log in seconds, tag what's going on, and let Moodis show you the patterns. ## Your Happiness Score A clear 0–100 number that summarises your mood. See it grow as you check in, and watch it shift week over week. ## Category Impact Tag entries with Work, Family, Sleep, Health and more. Moodis compares each category to your average so you can see what's lifting you up — and what's weighing you down. ## Streaks & milestones Daily check-ins build a streak. Hit 3, 7, 30 or 100 days and Moodis celebrates with you. ## A real timeline Every mood is its own card with notes, photos and categories. Browse by day, search your memory, edit anything. ## Calendar view See your month at a glance — each day coloured by how you felt. Start the week on Monday or Sunday, your call. ## Twelve handcrafted themes Indigo, Sunset, Ocean, Forest, Rose, Midnight, Lavender, Mint, Peach, Gold, Slate and Berry. Free for everyone. ## Daily reminders An optional gentle nudge at a time you choose. Skip a day and your streak is safe — until you skip two. ## Private by default Your entries live on your device. Optional iCloud sync keeps them in step across your iPhones and iPads using Apple's encryption. No accounts, no servers, no ads, no analytics on your moods. ## Face ID lock Lock Moodis behind Face ID, Touch ID or your passcode in one tap. ## Moodis Plus A one-time upgrade — no subscription, no renewals. • Unlimited mood entries (the free plan stops at 30) • A full year of historical insights • One-time purchase, yours forever ## Made with care Moodis is built by an independent developer who cares about a quiet, honest mental-health tool.
