RainAware

Review by eFreeware

RainAware is a weather app from the developer of the same name, built around one question: when will rain reach me, and when will it stop? Its headline tool, Rain Clock, puts that timing up to three hours ahead for your location, and the rest of the app supports it with radar, satellite imagery, alerts and map overlays. The app costs $4.99 up front, carries no ads, and offers in-app purchases.

The reason to consider it is focus. Plenty of weather apps tell you there is a 60 percent chance of rain this afternoon; RainAware is built to give you a time window instead, and then let you dig into the imagery behind that window if you want to. That combination of a simple answer on top and serious meteorological detail underneath is what makes it interesting, and it is also what shapes who gets the most from it.

The people this app is built for

I would expect RainAware to appeal most to people whose plans turn on short-term rain: someone deciding whether to start a long walk now or wait, a parent timing an outdoor event, a contractor watching a work window, or a boater tracking storms across a bay. The Rain Clock answer is the part they would use every day, and the alert customization means they can set it to warn them only when rain is close enough or long enough to matter.

There is also a clear second audience: weather enthusiasts who like to look at the data themselves. The map overlays, trend graphs, site lists and drawing tools are aimed at people who want to annotate a radar loop or check wind direction at a ballpark before they commit to a seat. The developer's coverage note points to the USA and southern Canada as the strongest area, with satellite and local radar reaching from Hawaii to the Caribbean.

If you want a free app that shows a daily forecast and little else, this is a paid download with a subscription layer on top, and the depth here is the point of it. If you enjoy tuning settings until the app behaves the way you think, the extensive customization is likely to be a draw rather than a chore.

Rain Clock and the alert system

Rain Clock is the feature everything else orbits. It shows rain timing for your location up to three hours ahead, phrased in plain terms, so you get a start time and an end time rather than a percentage. The background images change to match the weather outside, which is a small touch that makes the main screen feel connected to conditions rather than abstract.

Alerts are where the app earns its keep for planning. Alerts cover rain arriving or clearing, plus severe weather threats. The developer gives you control over how alerts are timed, how long rain must last to trigger one, how close it must be and how often alerts arrive, which matters because a rain alert is only useful if it arrives early enough to change what you are doing and not so often that you start ignoring it.

Tapping an icon jumps the map to that location, which is a sensible way to move from a summary line to the actual picture without hunting through menus.

Radar, satellite and the map tools

The standard version includes regional radar, satellite and one-hour precipitation imagery. You view it over a regional domain and can move that domain anywhere to inspect weather in another area, which is useful when you are watching a system approach a place you care about rather than the place you are standing.

Overlays add context: surface observations, lightning, hurricane tracks, storm reports and moving ship observations. Landscape mode gives you a bigger map with additional pan and zoom controls, and a long press burst-loops the imagery faster so you can pick out trends instead of stepping through frames one at a time. Watches, warnings and advisories cover hazards including severe storms, floods, winter weather, wind, fire and marine alerts.

Beyond the map, there are 36-hour trend graphs for temperature, wind, cloud cover and precipitation amount and type, plus a Forecast Clock that lays out the next eight days in a Today/Tonight format with sunrise, sunset and moon phase. Site lists let you jump to nearby cities, airports, ballparks, speedways and golf courses, and the stadium views include wind direction so you can tell whether it is blowing in, out or across the field.

Drawing tools let you mark up the map, add text, lay your annotations over weather imagery and share the result. Weather badges flag rapid changes in rain, temperature, clouds or wind, and they are configurable, so you can decide which shifts are worth a visual nudge.

What the subscription adds

RainAware offers in-app purchases, and the developer describes a set of subscription features that sit above the standard version. The most consequential is full-map access, which removes the regional limit on the weather map. Storm cell tracking filters cells and shows motion, hail potential, rotation and more, and national radar products bring in Echo Tops, Hail Swaths and Rotation Tracks. Reflectivity and velocity products come from single-site radar, and the national view can be joined by radar from Hawaii, Alaska and Puerto Rico.

Subscribers also get expanded satellite imagery with water vapor and colorized visible layers for cloud-top analysis, plus additional alert types covering lightning proximity, severe storm reports and a second location. The RainPro tool lets you interactively refine precipitation motion to sharpen rain timing, and environmental layers show threat areas, VAD wind profiles, isobars, CAPE, updraft helicity and 500 and 850 mb charts.

There is more on the professional end: a warning and observation monitor with filtering and sorting, advanced surface observations plotting thousands of stations, ships and buoys with water temperature and wave height, longer loops running to 36 frames and as far as 12 hours ahead on capable devices, and an aviation mode that uses FAA sectional maps as an underlay, shows flight rules at stations and displays winds aloft. Advanced drawing tools add fronts, time-matched drawings and shapes, and settings for performance cover memory, caching, panning and image tiling. The recent update brings stability fixes and, for subscribers, more precise time matching of overlay fields such as CAPE.

Price, ads and purchases

RainAware costs $4.99 to download. It contains no ads, and it does offer in-app purchases, which the developer describes as subscriptions that work across supported devices and unlock the features listed above.

So the cost picture is a paid app plus an optional subscription layer for the heavier map and analysis tools. Whether that is reasonable depends on how much of the subscription set you would actually use. The standard version already covers rain timing, alerts, regional radar and satellite, warnings, overlays, graphs and the forecast clock, which is a substantial package on its own.

The app has been on Google Play since December 2013 and was last updated in September 2026. It sits at a 3.5 average from 154 ratings, with more than 10,000 installs.

Alternatives in the same space

The obvious comparison is a free general-purpose weather app. Those typically give you a forecast for the day, a radar view and severe weather alerts at no cost, and for many people that is enough. RainAware's case rests on the timing precision of Rain Clock, the alert thresholds you can tune, and the depth of the map tools, which is where the paid download and the subscription are meant to earn their place.

A second alternative is a dedicated radar app, the kind built purely around looping imagery and storm analysis. RainAware overlaps with those through its overlays, storm cell tracking and single-site radar, but it also carries the forecast clock, trend graphs, site lists and the rain-timing layer, so it aims to be one app rather than two.

If your interest is aviation weather specifically, there are tools built around flight planning. RainAware's aviation mode uses FAA sectional maps, flight rules at stations and winds aloft, but it is one part of a broader weather app rather than a flight-planning product. Where you land depends on whether you want rain timing at the center of things or as a side feature.

A considered buy for rain-timing planners

RainAware is worth the $4.99 if the question you ask most often is when rain will start and stop where you are, and you want the imagery and alerts to back that up. Rain Clock answers it directly, the alert settings let you decide how much warning you get, and the standard map tools are enough for most day-to-day use.

The subscription is the part to think about before buying. Full-map access, storm cell tracking, single-site radar, environmental fields, aviation mode and the longer loops are aimed at people who read weather seriously, whether for work, a hobby or a sport that depends on wind and storms. If that describes you, the extra layers are the reason to choose this app over a free forecast. If it does not, the standard version still does the core job.

Coverage is the other practical consideration. With an interest in short-term rain rather than a general forecast, RainAware is a focused tool.

What's new in version 2.1.8

Several fixes that improve app stability. [subscriber] More precise time matching of overlay fields (CAPE, etc).
