How it works

More than just labels.

Other apps let you write notes. obseed captures structured context — with dosages, time models, and automatic correlation across all your devices.

Step 1

Capture a tag

No free-text fields. Choose from 205+ system tags across 11 categories — supplements, sauna, symptoms, equipment, mood, and more. Add structured attributes: dosage, temperature, intensity, duration.

Step 2

Choose a time model

Real life is messy. That's why we support 6 time models: instant events, all-day states, intervals, date ranges, approximate times, and end + duration. Tagging adapts to your life, not the other way around.

Step 3

Correlate automatically

obseed instantly links your tag to all connected devices — Oura HRV, Whoop Recovery, Garmin Body Battery, Withings weight. Tag once, analyze everywhere.

The difference

Context changes everything.

The same wearable data. Once without context — once with. The difference is understanding why you're improving.

Without context

  • Numbers without explanation Your HRV is low today. Your recovery score is poor. But why? You stare at charts and can only guess.
  • Experiments in the dark You've been taking magnesium for three weeks. Is it actually working? Without structured data, it remains a gut feeling.
  • Silos, not a system Oura shows sleep, Whoop shows recovery, Garmin shows training. No tool connects the dots for you.

With obseed Tagging

  • Context at a glance HRV low? obseed shows you: red wine last night + 90-min training + 6h sleep. The answer was there all along.
  • Real n=1 experiments 400 mg magnesium glycinate, daily at 9 PM. Automatically compare against days without — and see whether your deep sleep actually improves.
  • Tag once, see everywhere Log a supplement in obseed — instantly see the correlation with Oura, Whoop, Garmin, and Withings at the same time.

A tag takes less than 30 seconds. After that, obseed works in the background — finding patterns you'd never see without structured data.

  • Structured attributes: Dosage, unit, brand, note — automatically adapted to each tag type.
  • 6 time models: One-time, daily, weekly, window, interval, cycle — whatever your protocol looks like.
  • Retroactive matching: Tags are automatically linked to your historical wearable data — see the difference immediately.

Who it's for

Who benefits the most?

Anywhere wearable data alone isn't enough to answer the one question that matters: Why?

Biohackers & self-experimenters

You test supplements, sleep rituals, and nutrition protocols — but without data, it's all guesswork. With tagging, you run real n=1 experiments with actual results.

"After 6 weeks of 400 mg magnesium glycinate at 9 PM, I see +14 min deep sleep on average. Without obseed, that would never have been measurable."

Endurance athletes

You know that training alone isn't enough. Equipment, nutrition, conditions — all of it affects your performance. Tagging makes it measurable.

"Carbon shoes vs training shoes, tagged across 12 weeks. Result: 11 sec/km faster at the same heart rate."

Health-conscious & symptom trackers

You want to understand what triggers your symptoms — headaches, sleep problems, energy crashes. Tagging gives you the data foundation to find out.

"After 3 months of tagging, I know the three factors that predict 80% of my migraines — and I can intervene before they start."
