Comparison
RunWeather vs Apple Weather for runners
By Iustin Nita · Updated
Apple Weather tells you what the weather will be; RunWeather tells you what that weather will do to your run. If you just want a forecast, Apple Weather is excellent and free. If you want to know when to run, how much conditions will slow you down, and why a run felt hard, that is what RunWeather is built for.
Apple Weather is one of the best general-purpose forecast apps: it's free, preinstalled on every iPhone, has minute-by-minute precipitation, severe-weather alerts, and a clean hourly view. Nothing here argues against keeping it.
What it does not do is interpret the forecast for running. Dew point is buried in the details sheet, there is no concept of a "good hour to run", and a 75°F reading looks the same whether the air is dry or so humid your sweat stops working. RunWeather takes the same underlying forecast data and answers the runner's questions directly: a 0-100 Run Score for every hour, the best window today and tomorrow, pace-adjustment guidance, and heat-strain (WBGT) safety flags.

When Apple Weather is enough
If you run casually, at whatever time fits your day, and mostly want to know if it will rain, Apple Weather answers that well, and adding another app won't change your running. It's also the better tool for general planning: radar, multi-day outlooks, and official warnings.
When RunWeather earns its place
The gap shows up in summer and in training blocks. If you choose when to run, care why a run felt hard at the same pace as last week, or train in heat and humidity where dew point decides everything, a raw forecast makes you do the interpretation. RunWeather does that interpretation with a published, research-based model: same engine in the app, the free web calculator, and the hourly heat-risk board.
Common questions
- Does RunWeather replace Apple Weather?
- For running decisions, yes; for general weather, no. Most RunWeather users keep a general forecast app for radar and alerts and use RunWeather to decide when to run and how to pace.
- Do RunWeather and Apple Weather use different forecast data?
- Both are built on professional numerical forecasts. The difference is interpretation: RunWeather converts the forecast into a 0-100 Run Score, best run windows, and pace guidance instead of showing raw values.
- Is RunWeather free like Apple Weather?
- RunWeather is free to download and use for forecasts, Run Scores, and best windows on iOS and Android. An optional Pro tier ($29.99/year, or $4.99/month) adds Strava history context and personalized insights.
