LunarLog — Moon Mood Tracker A mood tracker that keeps time with the Moon. Log how you feel each day, and slowly your mood diary starts to rhyme with the sky above it: the phase, the sign, the pace of the Moon overhead. A mood journal you'll actually keep Most daily journals ask too much. LunarLog asks for one tap. There are no streaks to break and nothing to catch up on, so a missed day stays a missed day instead of a small failure. What builds instead is a private record of your moods, and the patterns in it are usually the ones you'd never have noticed on your own. Your lunar mood diary and calendar Log your mood on a simple scale, then add notes and photos if the day deserves them Sleep and steps arrive on their own from Apple Health. Connect once and your past days fill in behind you A calendar where every square carries its true moon phase, so you can see where you are in the cycle at a glance A nebula dial holding the Moon's exact position, turning in real time Astrology, meeting your actual mood Mood by moon sign. Real astrology applied to your own feelings rather than a horoscope written for everyone Mood by moon phase. Which parts of the cycle lift you, and which ones sit heavy Mood by element. The Moon through Fire, Earth, Air and Water, and how each one lands for you Reviews "So surprised how my daily mood tracking helped me understand my mood! Thanks astrology!" "This is by far the best mood tracker on the app store, it connects my interest in astrology and my mood." "It's the only app that connects astrology and daily life." "Beautiful app, helps me to make friends with the moon and my own moods." LunarLog+ Live Moon Transit, the Moon arcing through the zodiac as it happens What Moves Your Mood, which ranks sleep, steps, moon phase, moon speed and moon sign by how much each one actually pulls on you Full Moon & Sleep, testing the old claim against your own nights rather than folklore Sleep & Mood, and Sleep by Moon Sign: the nights behind your days Steps & Mood, on how movement moves you Mood by Moon Speed, because the Moon hurries and lingers, and one pace probably suits you better Up to three photos on every journal entry A gentler kind of self-care Built for mental health and self-care rather than productivity. One honest check-in a day, and a quiet reminder from the Moon whenever you'd like one. Private by design Your mood diary lives on your device and syncs only through your own iCloud. No account, no ads, no tracking, now or later. Apple Health access is optional and read-only; LunarLog never writes to it. LunarLog+ is an optional monthly or yearly subscription. Cancel anytime.

Verdict
The clearest difference is in-app purchases: Luna Sync at none against LunarLog's 2. Luna Sync also leads on iOS requirement (16.6 vs 18.0). LunarLog's advantage is update cadence (weekly vs every 3 weeks). On price, ads and device support there is nothing between them.
