The free tier has no time limit and no catch. It includes dose logging, live medication tracking, the 7-day dose calendar, the journal with your last 28 days of history, logging for side effects and blood pressure, and the Clinician Summary read aloud at your appointment. Pro (£3.99/month or £29.99/year) adds the analysis layer: how the medication is working, readiness scores, correlation insights, sleep window and sleep debt, side effect and blood pressure trends, full history, smart notifications, Weekly Pulse, the zone-coloured chart and the written appointment summary you can share or export. There is no paywall on your first session, no countdown and no nag. Pro is available when you want more depth.
