Stress, measured from your own baseline.

Your resting heart rate is 72. Is that good? Unanswerable — unless it's compared to your own normal. Slowpulse learns what your heart does when you're calm, from your Apple Health history, and notices when it stops doing that.
When stress shows up, a guided 4-7-8 breath helps bring it back down. Nothing is scored against a population chart.
Nothing leaves your device. No account, no server, no analytics, no third-party SDKs — Slowpulse makes no network requests at all. Verify it in Airplane Mode.
