What to sync before you ask Hydrogen
Sync is optional, but stronger web analysis depends on having the right windows and enough desktop coverage available to Hydrogen.
- Sync the comparison windows you care about most first.
- Coverage quality still matters more than raw quantity.
- Hydrogen is strongest when baseline and comparison periods are both clean.
The best sync decision starts with the question you plan to ask
People treat sync like backup — push everything up, sort it out later. That is not the right model. Sync exists so Hydrogen can read what you plan to ask about. Anything beyond that is overhead.
If you want a week-over-week comparison, make sure the desktop app captured those weeks cleanly first. Sync is there to support interpretation, not to replace the baseline the Windows app builds locally.
What to sync first
You do not need a giant history on day one. You need the recent windows that make your first useful prompt possible — and almost nothing else.
- Your most recent seven to fourteen days of normal work coverage
- Any days where fatigue clearly shifted and you want explanation
- Optional wearable context if you want stronger energy interpretation
When to wait
If your recent days are interrupted, unusual, or just incomplete, track a little longer before asking Hydrogen for strong conclusions. The AI does not get smarter by working off worse data; it gets confidently wrong.
A reasonable rule: if you would not yet show this week's data to a colleague as representative, you are not ready to ask the agent for an explanation either. Ask it about *coverage quality* instead. That is its own useful question.
