Traceline brings your supplements, sleep, HRV, mood and daily scores together on your iPhone — then turns them into understandable trends and structured trials when you make a change. For people who'd rather know than guess.
One month of the full app · monthly, annual or Founding Lifetime access after that · iOS only for now.
I'm not a wellness brand — I'm one person with slow COMT and an MTHFR variant who wanted to understand what my daily health data and supplement routine were actually saying. Every app I tried either sold me a protocol or dumped a wall of charts and left the thinking to me. So I built the honest version: one private place for the daily picture, the longer trend, and a careful before-and-after trial when I change something. It speaks the language of forms and variants and tells you plainly when the data is too thin to say. It's nearly ready — the launch list gets one email the day it's on the App Store.
Log supplements and a few useful ratings in seconds. Sleep, HRV and resting heart rate flow in from Apple Health — no duplicate forms.
Calm daily scores, history and charts turn the raw stream into something you can understand without decoding a wall of numbers.
When you start something new, run a structured before-and-after trial. A finding appears only when your own data supports it — with a straight "too soon to tell" when it doesn't.
An active change stays visible while you collect enough usable days. When the comparison is ready, Traceline shows the before-and-after and exactly how much data supports it.
Every pattern comes with how sure your data actually is — not just an arrow pointing up or down. Weak signal? It says weak.
Build a baseline, confirm the days you took it, and see the honest before-and-after on your own numbers.
It knows methylfolate from folic acid, methyl- from hydroxy-B12 — the distinctions that change how you actually respond.
Sleep, HRV and resting heart rate sync in, so your trial can use measured outcomes without making you re-enter them.
Optionally import a 23andMe or AncestryDNA file and it pulls out the handful of markers you track — COMT, MTHFR and more — entirely on your device.
Recovery, Sleep, Nutrition and Stress in plain words — never a red-alert. The signal reads as intensity, not alarm.
A supplement stack. Sleep and recovery data. Slow COMT or an MTHFR variant. Caffeine that hits you differently than everyone else. Whether you're watching the everyday trend or testing one deliberate change, Traceline helps you understand your own data without telling you what to do.
There's no account and no sign-up. Nothing is uploaded, nothing is sold, and there's no tracking of any kind. That isn't a setting you toggle — it's how the app is built.
Traceline is a self-tracking tool, not a medical device. It shows you patterns in your own data — it doesn't diagnose, prescribe, or tell you what to do. It'll debunk a supplement as readily as it confirms one, because that's the whole point.
Plain-language context for the questions that show up before you make a change.
