Best Dark Sky Alternatives for Apple Watch (2026)
Dark Sky answered one question brilliantly: is it about to rain, right here? Since Apple absorbed it, that intelligence lives inside Apple's WeatherKit — which means the question isn't "what replaces Dark Sky," it's "which app puts those forecasts to the best use on your watch."
What made Dark Sky special
Minute-scale rain awareness and zero fluff. Any real alternative needs to keep that focus: precipitation first, everything else second.
The candidates
Apple Weather
The obvious default — Dark Sky's DNA, free, decent complications. But it knows nothing about your day: it can tell you it will rain at 3 PM, not that your only gap for a run is 2:15–3:00.
Weathergraph
A lovely graph-first complication for people who want the full meteogram on their wrist. Deep, data-rich, and worth a look if you want all the weather variables.
CARROT Weather
The personality pick, with highly customizable complications. Great if you want snark with your forecast.
Calendar Weather
Ours, so judge accordingly — the only one here that draws your calendar on the rain timeline. The watch complication shows the next hours of rain, your events, and a green band on the driest window that fits your activity. It answers Dark Sky's question plus the follow-up: "…so when do I actually go?"
How Calendar Weather solves the real problem
Dark Sky told you rain was coming. Calendar Weather tells you what to do about it: the best-window engine searches the next 24 hours for the driest slot that fits each of your activities, inside the hours you're actually free — and shows it on your watch face.
FAQ
What happened to Dark Sky?
Apple bought Dark Sky in 2020 and shut the app down at the end of 2022. Its forecasting technology was folded into Apple Weather and the WeatherKit API that other apps can build on.
Is there a free Dark Sky alternative?
Apple's built-in Weather app inherited much of Dark Sky's precipitation forecasting and is free. Dedicated rain-planning apps add features on top, usually behind a subscription.
Which alternative works best on Apple Watch?
It depends what you want on your wrist. For a plain temperature, the built-in complication is fine. For rain timing against your actual schedule, you want a timeline complication like Calendar Weather's.
