Universal Tagging: Your wearable measures everything.
Except the why.
The missing context. obseed Universal Tagging adds structured information to your wearable data — supplements, sauna, symptoms, equipment — and automatically correlates it across all your devices.
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.
Capture a tag
No free-text fields. Choose from 290+ system tags across 10 categories — recovery, nutrition, symptoms, training, mental health, and more. Add structured attributes: dosage, temperature, intensity, duration.
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.
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.
What you can tag
10 categories. 290+ tags. Infinite insights.
From recovery to training, from symptoms to mental health — everything that affects your body can be captured with a tag in seconds.
Automatic Correlation
Every tag is automatically matched against all connected devices — simultaneously, retroactively, and without any manual effort.
Instantly matched against Garmin, Oura, and Whoop
In Action
Tag once.
See everywhere.
A tag takes less than 30 seconds. After that, obseed works in the background — finding patterns you'd never see without structured data.
- 290+ predefined tags: No blank slate — start immediately with the most common supplements, symptoms, and protocols.
- 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."
Women's health
Cycle, pregnancy, menopause — 25 dedicated tags capture PMS intensity, ovulation, breastfeeding sessions, and hot flashes. Everything correlates automatically with your wearable data.
"Since I can see PMS, sleep, and training together, I finally understand why some weeks just feel different."
Mental health & mood
20 tags for mood, stress, and cognitive performance — with positive and negative counterparts. Discover how sleep, training, and nutrition influence your mental health.
"Brain fog on days with less than 6.5h sleep: 4× more frequent. No wearable showed me that — only tagging did."
Medical & monitoring
Medication logs with active ingredient and dosage, blood pressure with posture context, blood sugar with fasting state — structured monitoring that correlates with your wearable data.
"Blood pressure, medication, and sleep quality in one view — my doctor was impressed by how well the data was documented."
Your wearables capture the numbers.
We capture the story behind them.
