02

A diary that builds itself

Log how you're feeling with severity, time of day, and custom tags in seconds. Your season fills in automatically — no effort, no spreadsheets.

03

Your whole season, at a glance

Heatmaps, charts, and species breakdowns show how your hayfever has tracked across weeks and months. Premium unlocks the full history view.
