TriLog

Log what no sensor can see — mood, energy, focus, symptoms — and line it up with everything else.

TriLog is The Personal Data Logger.

Log what no sensor can see. Line it up with everything else.

Apps and devices track your heart rate, steps, and sleep stages. They can't track how you felt at 2pm, whether focus crashed after lunch, or what symptom showed up before the weather changed. TriLog is a fast log for subjective experience — mood, energy, focus, symptoms, observations — anything only you can observe.

Then it puts that on the same timeline as the rest of your life: activities, notes, weather, pollen, barometric pressure, Apple Health metrics, and more. Not scattered across apps and memory — one clock, one week on one screen, so you can see what actually lines up.

Capture in seconds. Discover what predicts your best days.

FREE — LOG WITHOUT LIMITS

• Mood and energy throughout the day • Activities — work, sleep, exercise, leisure, anything • Sleep quality, duration, and wakefulness (Day Launch) • Meals and short observations (including calorie notes) • Health and symptom observations (freeform notes) • Journal entries and Day End reflections • Menstrual cycle notes • Habits — daily checkoffs, no streak pressure • Timeline, Metrics Grid, Charts, and note search

A fast log for what you observed, when — and what else was going on at the same time.

ALIGN EVERYTHING ON ONE TIMELINE

Weather, pollen, air quality, UV, and barometric pressure sit alongside your entries. Apple Health metrics — sleep stages, resting heart rate, HRV, weight, steps — share the same chart and Metrics Grid. Built for correlation: did this week feel worse because of sleep, pressure, screen time, or something you logged Tuesday?

THE DATA NOTHING ELSE CAPTURES

Sensors capture what your body does. Mood journals capture how you felt. Neither lines them up. TriLog does both — a continuous record from the inside, on the same clock as everything else.

Why do I have good days and bad days?

What predicts my energy crashes?

What actually improves my focus?

What's behind a symptom no test has explained?

These questions are unreachable by sensors and unreliable from memory. They become answerable when you have a continuous record from the inside.

Built for people who already try to track energy, symptoms, or focus — and need one timeline instead of Notes, spreadsheets, and mood-only journals.

DESIGNED FOR SPEED

Capture has to be effortless or it won't survive a hard week.

TriLog was built around that constraint. Three taps to log mood, energy, and what you're doing. No forms. No typing. No menus. Get back to your day.
