If checking the sky is part of your morning routine, the Weather app from OneLouder Apps is built for exactly that. It combines a 10-day forecast, a 48-hour rain outlook, and a Health Center that tracks air quality and pollen, all in a free package that has crossed 100 million installs and holds a 4.6 average from over 254,000 ratings.
What makes it worth a closer look is the breadth of what it puts on one screen. Rather than checking one source for rain and another for pollen, you get forecasts, radar, and health-related readings in the same place. The developer's pitch is hyperlocal accuracy, and the feature set backs up the ambition even if the marketing language is doing some heavy lifting.
The app launched in early 2023 and was last updated in September 2026, so it has had time to mature. It is free to install, supported by ads, and offers in-app purchases. That combination shapes who will get the most from it: people who want a lot of weather information without paying upfront, and who do not mind the trade-offs that come with that model.
Forecasts built around the next two days
The core of the app is a 10-day forecast paired with a 48-hour precipitation outlook. The developer describes minute-by-minute rain forecasting for the near term, which is the kind of detail that matters when you are deciding whether to walk the dog now or wait half an hour. Ten days out is enough to plan a weekend trip or a outdoor event without needing a second source.
Beyond the headline numbers, the app lists more than 15 weather data points. That includes UV index, dew point, visibility, humidity, wind speed, and atmospheric pressure. For most people, a handful of these will be the ones they actually check; the rest are there for anyone who wants a fuller picture, such as gardeners watching dew point or photographers tracking visibility.
Customizable units and multilingual support round out the basics. You can set the app to the measurement system you think in, and choose from multiple languages. Dark and light themes are included as well, which matters if you tend to check the forecast before sunrise or after dark and want to reduce eye strain.
Radar maps that look ahead, not just behind
Radar maps include several layers and a future view. The developer says these can be used to track thunderstorms, typhoons, hurricanes, rainfall, and snowfall. Future radar is the more interesting half of that: instead of only showing where precipitation has been, it projects where it is heading, which is useful when a storm is approaching your area.
Multi-layer maps mean you can stack different views rather than toggling between them. I would expect this to appeal to anyone who likes to see the shape of a weather system rather than just read a percentage. It is the kind of feature that rewards a few minutes of exploration, and it sits alongside the forecast data rather than replacing it.
For everyday planning, the radar is probably overkill on a clear day. On a day when the sky looks threatening, though, having a future radar view in the same app as your hourly forecast saves switching between tools. That convenience is a large part of what the app is selling.
The Health Center and what it tracks
The Health Center is the section that distinguishes this app from a plain forecast tool. It covers wind chill, moisture, air pollution level, and pollen count. The air quality index gives real-time readings for your area, and the allergy outlook tracks grass, weed, and tree pollen separately. Pollution levels are broken down into PM10, PM2.5, O3, CO, NO2, and SO2.
Advice is offered for sensitive groups as well as everyone else. That framing suggests the developer has in mind people who need to modify their plans based on air quality or pollen, not just those who are curious. If you or someone in your household deals with asthma or seasonal allergies, this is the part of the app most likely to earn a place on your home screen.
The sun and moon tracker fits the same planning mindset. It shows sunrise, sunset, moonrise, and moonset, along with moon phases including New Moon and Full Moon. That is useful for planning evening activities, photography, or anything else that depends on daylight hours.
Widgets for checking the weather at a glance
The app offers more than 10 customizable widgets in sizes ranging from 1x1 up to 5x2, including 2x1, 2x2, 2x3, 3x4, 4x1, 4x2, 4x3, and 5x1 formats. That range means you can fit a compact temperature readout on a crowded home screen or dedicate a larger block to a fuller forecast. The developer's stated aim is to let you see the weather your way, and the variety of sizes supports that.
Widgets are often the deciding factor for whether a weather app stays installed. A small widget that shows current conditions without opening anything is convenient; a larger one that shows the next few days can replace a daily check-in entirely. Having both options in one app is a sensible arrangement.
That consistency is a small thing, but it is the kind of detail that makes a widget feel like part of the system rather than an afterthought.
Ads, purchases, and what the free model means
The app is free to download and supported by ads. It also offers in-app purchases. The developer notes that information from your use of the app may be shared with partners to deliver personalized ads and improve services, and that you can modify your choices as explained in the privacy policy. That is a standard arrangement for a free weather app, but it is worth understanding before you install.
In practical terms, the trade-off is straightforward: you get a broad feature set without paying upfront, and the app is funded by advertising and optional purchases. If you prefer a weather app with no ads at all, this one is not that.
The app is rated Everyone and sits in the Weather category. None of that is unusual, but it is the kind of thing to check if you are particular about how your home screen is arranged.
Who gets the most from this app
The clearest audience is people who want a single place to check forecasts, radar, and health-related readings. If you plan outdoor activities, have allergies, or simply like knowing the UV index before you leave the house, the combination of features here covers a lot of ground. The 10-day forecast and 48-hour rain outlook handle the planning side, while the Health Center handles the day-to-day comfort side.
It also suits anyone who values home screen widgets. The range of sizes and the ability to customize units and themes mean you can shape the app around how you actually check the weather, rather than adapting to someone else's layout. For a free app, that level of customization is a strong point.
The app is less compelling if you want something minimal. There is a lot here, and the Health Center, radar layers, and 15-plus data points will be more than some people need. That is not a flaw so much as a focus: the app is built for people who want detail, and it delivers that detail in a package that remains free to install.
A detailed forecast companion for planning ahead
The Weather app from OneLouder Apps earns its install base by covering a lot of ground in one place. The 10-day forecast, 48-hour rain outlook, future radar, Health Center, and widget options give you more than a simple temperature readout.
The caveats are the ones that come with the free model: ads are present, in-app purchases are offered, and usage information may be shared with partners for personalized advertising. If those terms are acceptable to you, the feature set is broad for the price.
I would recommend this to anyone who wants a weather app that doubles as a planning tool, particularly if allergies or air quality are part of your daily considerations. It is also a good fit for widget users who want options. If you prefer a stripped-down forecast with nothing extra, the breadth here may feel like more than you need.
The short verdict
A feature-rich, ad-supported weather app best suited to people who want forecasts, radar, and health data in one place.
