Private beta

See the full shape of an illness.

When you feel off, your health data is scattered across symptoms, apps, and devices. Off Baseline groups it into one episode, compares it with your normal range, and creates a summary you can keep or share.

Planned for iPhone, Android, and the wearables you already use.

Why Off Baseline

Illness in context

Your symptoms and wearable changes belong together.

Symptoms are usually recalled later. Wearable readings stay inside separate apps. Off Baseline gives each illness a beginning, a timeline, and a recovery point so the full episode is easier to understand and share.

One episode. Your normal range. A clearer recovery record.

Clear limits

Context, not diagnosis.

Off Baseline organizes symptoms you enter and data from connected wearables. It does not detect, diagnose, or treat illness.

If you think you may be having a medical emergency, contact local emergency services immediately.
