The app is Clime Pro on iOS, they lock full access to Hurricane Milton data behind a $10 USD per week paywall.

Throwing it out there, but https://www.nhc.noaa.gov is hands down the best hurricane tracking site. It’s low Bandwidth, quick, lightweight, legit data backed, and generally the source data for most other weather sites.
