MoodGenius is the calm, science-backed mood journal for people who want to feel better — without spreadsheets, charts, or guilt. Best experience: Apple Watch + iPhone MoodGenius reads sleep, activity, heart rate, and mindful minutes directly from Apple Health. The richer your health data, the sharper the correlations. (Manual metric entry on the roadmap.) Log your mood in seconds. MoodGenius quietly correlates each entry with your Apple Health data — sleep, activity, heart rate, mindful minutes — and turns the patterns into one or two specific things you can do today. Not generic wellness clichés. Not "you should sleep more." Real micro-actions, grounded in your own data: • "Go to bed 30 minutes earlier tonight — your low-mood days follow nights under 6h sleep." • "Try a 5-minute walk after lunch — your afternoons rate higher when you move before 2pm." • "Box-breathe for 90 seconds before your next meeting — your stress climbs on Tuesday mornings." Why it works: • Quick logging — under 10 seconds. A mood, an optional note, done. • Apple Health–native — sleep stages, activity, mindful minutes feed the engine automatically. • Pattern detection — the app finds the correlations so you don't have to read charts. • Actionable insights — every Patterns view ends with something to do, not just something to know. • Editorial design — calm sage palette, soft typography, no clutter, no streaks pestering you. Privacy first: • Your mood data is encrypted in transit and at rest. Yours, not ours. • Apple Health data is used only to generate your insights — never sold, never used for advertising. • No ads. No data brokers. No social feed. Built for people who: • Want a journal that does the analytical work for them • Are tired of habit trackers that demand fifteen fields a day • Already wear an Apple Watch and want it to mean something • Prefer evidence-based suggestions over horoscope-style advice MoodGenius doesn't promise to fix your mood. It gives you the smallest, most likely-to-help action — backed by your own data — and gets out of the way. Start logging. The patterns will find you.

Delphi is a journal where you write with the stars. What to write? As astrologers, we look up. Every day, a unique reading based on your sun, moon and rising. Delphi won't tell you your future; it will draw you inward and onto the page. The goal is to find your voice and softly encourage you to build up the habit of writing. Once writing is a habit, Delphi begins to analyze. Without any of your entries leaving your phone, Delphi interprets your mood and plots it against the stars. At any time you can see how your feelings are affected by different astrological events.
