What you get

Pulse was built for exactly this.

The core features that make Pulse different from the generic alternatives.

On-device only

Your moods live in encrypted storage on your phone — no account to create, and you can log with airplane mode on.

Two-tap logging

Pick a quadrant on the energy-by-pleasantness mood meter, then a word — the whole daily check-in clears in under five seconds.

Insight engine

After about two weeks of entries, Pulse surfaces correlations and weekly patterns instead of just handing you a logbook.

Calendar mosaic

A color-per-day grid that lets you see a month of feeling at a glance.

Honest streaks

The counter tracks your last seven days, so missing one day never wipes out months of progress.

Encrypted iCloud sync

Optional sync across your devices through Apple's private database — even Apple can't read it.

How it works

Three steps. No account. No tracking.

  1. 01

    Download once

    Install Pulse from the App Store when the waitlist opens. No account setup — it works the moment you open it.

  2. 02

    Use for ninety seconds a day

    The product is designed so the useful thing takes less than two minutes. Anything longer and you stop. We know.

  3. 03

    Notice what changes

    Patterns surface after two to three weeks. The data is yours alone — no cloud, no report to anyone.
