The brief

A trusted migraine prevention tool with strong user value, but no cohesive subscription experience.

WeatherX had already built a loyal audience among people affected by barometric pressure-triggered migraines. Users relied on the app’s predictive pressure alerts and pressure-filtering earplugs as part of their preventative migraine routine.

What it lacked was a subscription ecosystem that connected recurring earplug delivery, premium migraine tracking, and long-term user engagement into a cohesive experience.

Clarion redesigned the subscription experience and monetisation flows to support long-term preventative care engagement.

Last mile · UX + Store

Connected preventative migraine tools with a subscription experience users understood.

Users already trusted WeatherX for pressure-trigger migraine alerts, but the premium value proposition wasn’t clearly connected to long-term migraine management.

We redesigned onboarding, subscription flows, and premium feature presentation to clearly communicate the value of recurring earplug delivery, migraine tracking, and personalized pressure sensitivity insights.

Tier 2 · Monetization

Turned WeatherX+ into a preventative migraine subscription experience.

The greatest pain point with monetization was finding the right moment that feels meaningful for users.

The greatest challenge was connecting the physical product, premium app features, and recurring value into a subscription model users immediately understood.

“Our users trust WeatherX with their daily routine. Clarion pushed on the hard product calls, connected subscriptions to what users already loved, and we see the difference in retention every week.”

Growth and adoption figures (MAU/DAU/WAU, retention, geography, and the version chart) are derived from Firebase exports through Apr 2026. Headline MAU growth and App Store rating callouts reflect client-reported outcomes. The +52% DAU headline compares maximum v6.3.0 daily actives to the mean over export days 320–419. Earplug subscription lift and ARPU are illustrative for storytelling until client sign-off.
