Your blood results, your wearable and a doctor's plan

Your account

Kaizin works best in the app. This page is here so you can sign in, see your plan and pay on a laptop. Your readings, daily check-ins and the detail behind each marker live in the iOS app, where they belong.

Payment is taken here on the web, not in the app. Apple requires that for anything involving a physical test or a doctor, and it means your whole payment goes to your care rather than a store fee.

Track

£15 a month. Wearable syncing, daily check-ins and trends, no blood test. Oura Ring connects in your browser today; Apple Watch connects when the iPhone app ships.

Core

Early access. A finger-prick biomarker kit at home, a GMC-registered doctor who reads it and writes your plan, and the AI coach between tests. Founding testers get a price below the launch price. Join and we will contact you.

Core Plus

Not on sale yet. Your panel is drawn at a clinic, so it includes the tests a finger prick cannot do, homocysteine and fasting insulin among them, with one targeted retest and a video consultation with a GP. Join the waitlist and we will email you the price when it opens.

Ultimate

Not on sale yet. £999 a year, as £549 to start and then £37.50 a month. Around 90 markers, homocysteine included, a named doctor, two 30 minute consultations and two targeted retests across the year.

Prices are shown again at checkout before you pay. You can cancel within 14 days for a full refund, and after that from Manage billing.
