Define variables. Log moments as they happen. Run studies that look for cause and effect in your own patterns.
anything you want to track, in any form — number, scale, yes/no, duration
moments recorded in ten seconds, timestamped, always there
two variables, one question — does this cause that?
Define anything — a number, a scale, a yes/no. Each variable collects entries over time and waits for the right question.
Caffeine, sleep quality, focus, mood, exercise — or anything stranger your life calls for. Variables have types, optional daily reminders, and a sparkline that shows recent shape at a glance.
A single tap from the today screen. Pick what you're logging, enter a value, done.
Recent variables surface first. The log becomes a timeline — the shape of your day, preserved exactly as it happened.
Choose two variables. Logfolder looks for correlation across your entries and returns a calm, honest read.
Emerging. Inconclusive. Needs more data. No false certainty — just your own patterns, surfaced carefully. Run as many studies as you like, and add new entries to watch them grow.
Logfolder scans gaps in your day against your usual patterns and reminders, surfacing three gentle suggestions — water at 10 am, lunch at 12:30, mood at 3 pm.
