DayLo: AI Mood Diary
One tap. That's the whole app.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Mood tracking shouldn't take five minutes. DayLo takes one tap.
Open the app. Tap green if your day was OK, pink if it wasn't. That's the whole check-in. No journal prompts. No forms. No streak guilt.
WHAT HAPPENS AFTER THE TAP
• A short AI insight about your day, based on your mood plus the context DayLo already knows — weather, steps, sleep, heart rate.
• Pattern detection that surfaces real trends: "three tough Mondays in a row," "good days correlate with 8k+ steps." Ten different pattern types, built from your own history.
• Monthly Wraps — a wrapped gift waiting on the 1st. Tap, watch the fog clear, see your month in two precise sentences.
CONTEXT, AUTOMATICALLY
You don't fill anything in. At the moment of your tap, DayLo pulls:
• Weather and temperature
• Steps, resting heart rate, sleep hours, HRV (Apple Health)
• Menstrual phase, if you track it
• City and country
WHEN YOU WANT TO SAY MORE
Add a short note, record a voice memo, snap a photo, or use the 2-question AI interview. All optional. All under a minute.
PRIVACY
Your entries are private — locked to your account via Apple Sign In, stored encrypted in an authenticated database, never sold, never used to train anything. No ads. No tracking.
PRO ($1.99/month)
Voice input is part of DayLo Pro. The one-tap core stays free forever.
Built for people who want the insight of a mood diary without the friction of journaling.
• A new day now greets you properly — the app resets at midnight instead of showing yesterday's check-in.
• Tags and notes now live separately: cleaner entries, sharper AI insights.
• Streak milestones — 7, 14, 30, 50, 100 days — get a real celebration. No questionnaire, just confetti.
