Budget factor
WeatherKit pressure can adjust the daily budget when Weather is enabled. Low pressure is the default sensitivity direction, but you can reverse that if high pressure is harder for you.
Custom pressure alerts
Advanced Budgeting lets you turn pressure alerts on or off, choose low-pressure or high-pressure direction, set the hPa threshold, and set the minimum cooldown between alerts.
No frequent polling
Metered reuses the weather data it is already fetching for the budget. It alerts only when pressure crosses your configured threshold and the cooldown has expired.
