Trace's pattern engine correlates meals, sleep, workouts, and labs to find what's really behind how you feel — problem-solve symptoms with evidence, not guesses.
Trace is a health coach that actually looks at your data.
At its core is a pattern engine: it cross-references everything you log - food, workouts, weight, sleep, water, mood, supplements, meds, bloodwork - to find the real, statistically gated relationships hiding in your own numbers. Feeling bloated, foggy, or just off some days and not others? Trace looks for what is actually correlated - a supplement, a short night, a food, a training day - instead of guessing, so you can problem-solve your own symptoms with evidence instead of hunches.
Log by chat, photo, voice, one-tap routines, or automatically from Apple Health. Say "catch me up" and talk through your whole day at once. Upload bloodwork and Trace reads the whole panel.
- Pattern engine: finds real correlations between your habits and how you feel - no horoscope insights; if the data does not support a pattern, Trace says nothing
- Chat-first coaching grounded in every entry you have logged
- Snap a meal photo - logged with calories and macros, grounded in the restaurant's real menu when one can be found
- Two-way Apple Health: weight, activity, sleep and vitals flow in, and meals or water you log in any other app are counted here too
- Saved workout routines you log in one tap
- Daily insight on your Today screen, plus a weekly review each Monday
- Bloodwork, trends, and goals in one place
- Email a report of any section to your doctor or trainer as a spreadsheet
- Your data stays yours: no ads, no trackers, delete everything any time
Trace is coaching, not medical advice.
