Today on a phone. Late is amber, never red.

A tracker that keeps to the facts of your day.

One screen, one answer

Doses sit in Morning, Midday and Evening, with a ring and a single line of progress. One tap logs Take. Skip is a real answer too.

It names the thing you take

Every item comes from a catalog: openFDA for medicines, NIH DSLD for supplements. Not listed? Describe it yourself. Strength sits apart from the name, so a typo can’t turn K2 into K3.

Private by construction

What you take is health data. dooz logs ids and counts, never the contents of a row.

Intake totals

An absence never becomes a number.

dooz adds each substance up across every product you log. When a number can’t be computed honestly, it says so, and says why. No blank, no quiet zero.

History, without judgement

Five weeks at a glance, 30-day bars per item, and the patterns: your streak, and the time of day you answer most and miss most.

Works with no signal

dooz opens offline. Taps wait on your phone and sync when the network is back, and a chip says which state you are in.

A shopping list that writes itself

Mark each item have it, buy soon or out. The ones running low gather on one list.

The evidence library

What trials measured, one outcome at a time.

For each supplement and each outcome: a grade on one scale, the direction trials found, and every study it rests on. Open to anyone, no account needed. Sources are never behind a paywall.

  1. High Consistent results across well-run trials.
  2. Moderate Probably right; the size of the effect could change.
  3. Limited Some trials, inconsistent or small.
  4. Very limited A few small or low-quality trials.
  5. No effect found Trials measured it and found nothing. A finding, not a gap.
  6. Not studied No trial measured it. Often a popular claim.

A grade belongs to one outcome, never to a substance. There is no overall score.
Nothing published here yet. Every entry is read by a person before it appears.
