TriLog is a personal log for the patterns nobody else tracks. Capture mood, energy, sleep, symptoms — anything that varies — and see what's actually connected.
Built for people trying to engineer their own energy, focus, and symptom patterns.
Then this is built for you. If you're looking for streaks, scores, daily affirmations, or a wellness journal, there are plenty of apps for that — this isn't one of them.
Mood, energy, what you're doing. Capture has to be effortless or it doesn't survive a hard week.
A dense visual grid of your whole week. Patterns that vanish in a list of entries become obvious here.
Mood, energy, sleep, steps, weather, cycles, pollen — every signal in the same table, day by day.
Short observations — bad sleep, back hurts, coffee with Alex — not journal paragraphs. Tag with j for a full journal entry; attach photos, export anytime.
Symptoms, supplements, focus ratings, pain levels, sleep onset — anything you suspect might matter. Stack possible causes against effects in one grid.
Weekly activity breakdowns — how many hours went to work, sleep, exercise, leisure — vs. where you thought they went.
Optional morning and evening reflections — sleep quality, tomorrow's targets, end-of-day notes. Skip whenever; the chart still reads.
Daily checkboxes for the things you're trying to keep doing. Missed days don't blow up a score. The grid still tells you the truth.
A free, open-source desktop viewer reads your TriLog export and lays months — even a full year — on one screen. Built for the long-horizon patterns the phone view can't fit.
If you're hunting for what's affecting your focus or mood, the daily screen-time total your phone shows you is too coarse to be useful. TriLog logs phone use by the hour — stacked next to your mood, energy, activities, and sleep — so you can finally see whether last night's two-hour scroll really was the thing that wrecked today.
Not by remembering. Not by guessing. By logging enough, long enough, that the answers show up in the chart.
You can't answer these by remembering. You can answer them by logging.
Your sense of the last six weeks is reconstructed. The chart isn't.
Weekly rhythms are invisible scrolling through entries. They're obvious on a dense grid.
Three taps, no streaks, no scores, no notifications you didn't ask for. Designed not to need your attention.
Weather, moon phase, daylight, cycles — overlaid automatically so you can see what else was happening that day.
A year of data changes how you understand yourself. TriLog is built to be used for years, not a 30-day challenge.
