Your history is never locked behind a paywall. No ads, no data selling, private notes stored encrypted.

Lower the TV, skip the questions, stay nearby without demanding attention.

| The Status Quo (Solo Trackers) | The DuoPhase Attunement |
|---|---|
| She feels overwhelmed during PMS and assumes he should intuitively know what's wrong. | She taps a 6-hour need ("Give me quiet") in a few seconds. |
| He walks on eggshells, misinterpreting her hormonal fatigue as emotional distance or rejection. | His phone tells him she shared what would help, with a plain idea of what to do: "Lower the TV, skip the questions, stay nearby." |
| Disagreements happen because neither partner understands the underlying biological reality. | Both check in daily on energy and answer one connection question together. |
Each one turns a moment you used to guess through into one clear step.
The Timed Needs Engine
Pick what would help and for how long: Listening, Comfort, A practical hand, Quiet, or Time before talking.
