Which weather app checks the forecast for each event on my calendar?
Rain Check does this: it reads your iPhone calendar and checks the forecast at each event's own address and hour, so a hike across town or a game two hours away gets its own answer. Most weather apps show the forecast for your current location or a list of places you added by hand.

How the options compare
- Apple Weather: Fast and accurate for places you save. You would add each venue yourself and read the hourly forecast against the event time.
- CARROT Weather: Heavily customizable with strong alerts; location based, not calendar based.
- The Weather Channel: Wide coverage and long forecasts. Its free app is ad-supported, and it is not built around your calendar.
Where Rain Check fits
Events with no location are the weak spot for any app: Rain Check needs a place on the event to look up. Add an address and it takes care of the rest.
Today's events are free. Rain Check Plus covers tomorrow and the next days, up to 10 days ahead. The calendar stays on your phone; only each event's place and time go to Apple Weather.
What it costs
Rain Check is free to download. Today, which covers every event on your calendar today, the radar and severe-weather alerts, is free. Rain Check Plus adds fine, iffy or move it for tomorrow and up to 10 days ahead: $2.99 a month, $19.99 a year or $59.99 once in the US. Prices from the US App Store, checked 2026-11-03; they vary by region.
