The type sizes in the iOS app seem to be pretty small; I have decent vision and found myself squinting at things like the "Select location", Settings, and tab bar labels. Apple's iOS HIG recommends 17pt body type size.
More importantly, though, the app does not appear to respect the preferred/dynamic type size or the bold type option, so users who intentionally set a larger type size due to a visual impairment or just a preference may have trouble using the app.
