Read full descriptionHide full description
WeatherDiff does more than show today's temperature. It helps you understand what changed from yesterday, what may change next, and what that means for getting dressed or heading out. With WeatherDiff, you can quickly check: * How much warmer or cooler today feels than yesterday * Better windows for going outside * Notable weather changes across the next 7 days * When rain may start or clear * Weather differences between saved cities * Outfit guidance based on your personal comfort preference WeatherDiff is built for quick daily decisions before you leave home, commute, meet friends, or plan a short trip. It turns temperature, rain, wind, and air quality into simple change-focused guidance, so you can prepare with less guesswork. You can also use alerts and home screen widgets to notice meaningful weather changes earlier. Weather data and suggestions are for everyday reference only. For severe weather or safety-critical decisions, always follow your local official weather alerts. -------- Terms of Use: https://weatherdiff.com/eula Privacy Policy: https://weatherdiff.com/privacy-policy

RainWatch shows the weather on your Apple Watch as an animated 3D cloud instead of a table of numbers. One glance tells you what it's like outside: the cloud frowns when it rains, hides from lightning, drifts in fog, holds on in the wind and steps aside when the sun comes out. ONE CLOUD, EVERY KIND OF WEATHER Rain, thunderstorm, snow, sleet, fog, wind, cloudy, partly cloudy, sunny, and their night versions. City, temperature, condition and chance of precipitation are always shown as live text over the animation. ON YOUR IPHONE TOO RainWatch comes with an iPhone app: the same cloud above the full reading, a pull-up panel with the hourly and 7-day forecast and air quality, and the place where you search for cities. Cities you save on iPhone appear on your watch by themselves. FREE • Current weather for your location, on the watch and on iPhone • One saved city: search for it on iPhone, see it on the watch • Every animated weather state • Forecasts from Apple Weather • In English and Polish • No account, no setup, no ads RAINWATCH PREMIUM • Hourly forecast: tap the cloud on the watch, or open the panel on iPhone • 7-day forecast: press and hold the cloud on the watch, or open the panel on iPhone • Air quality on iPhone • Up to five saved cities on iPhone and on the watch • Swipe left between your saved cities on the watch RainWatch Premium is a weekly auto-renewable subscription with a 7-day free trial for new subscribers. You can buy it in the app on iPhone or on Apple Watch; one subscription unlocks both. The price is shown in the app before you confirm. Payment is charged to your Apple Account when you confirm the purchase or when the free trial ends. The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings. You can restore purchases and redeem Apple offer codes in the app. Requires watchOS 26.6 or later on Apple Watch and iOS 26.2 or later on iPhone. The watch shows the weather for where you are on its own. Location is optional. Without it, search for a city and RainWatch shows its weather. With it, your location is used only to fetch local weather, show the name of the place and, on iPhone, the air quality. It is sent to Apple and, for air quality, to the World Air Quality Index — never to us.

Verdict
The clearest difference is iOS requirement: WeatherDiff at 17.0 against RainWatch's 26.2. On price, ads, in-app purchases and device support there is nothing between them.
