Rainy Days: Hyperlocal Weather Radar & Forecast App

Rainy Days is a mobile weather application that provides real-time, hyperlocal precipitation data using live Doppler radar. It transforms your phone into a powerful tool for tracking rain, snow, and storms. Users choose Rainy Days for its highly accurate, motion-based forecasting, which visualizes weather patterns on an interactive map to show exactly when precipitation will start and stop in their immediate location.

Interactive Global Radar Map

The core of the Rainy Days experience is its dynamic global map. Users start by opening the app, which immediately loads the radar view centered on their current location. They perform pinch-to-zoom gestures to adjust the map’s scale and swipe to pan across different regions. This map displays real-time reflectivity data, showing the intensity of precipitation. The color-coded system allows users to instantly distinguish between light drizzle and heavy downpours. This direct interaction with live data is the primary way users of Rainy Days conduct their own immediate weather analysis.

Live Storm Tracking and Motion Forecasts

This feature allows users to predict a storm's path. By observing the animated loop of radar history on their Rainy Days map, users can visually extrapolate the direction and speed of approaching weather. The app provides on-screen tools to play, pause, or adjust the speed of this animation. This progression from observation to prediction enables users to determine if a storm is moving toward or away from their area, making Rainy Days an essential tool for planning outdoor activities with precision.

Multi-Source Data Integration for Accuracy

Rainy Days does not rely on a single data provider. Instead, it aggregates and processes meteorological information from a network of global radar sources and satellite feeds. Users benefit from this automatically; the app intelligently selects the most reliable data source for their viewed region. This ensures that a user in Europe receives optimally accurate information, while a user checking on Rainy Days in Alaska gets data from the most appropriate local station, creating a consistent and trustworthy experience worldwide.

Location-Specific Search and Monitoring

Beyond automatic location detection, Rainy Days offers powerful manual search functionality. Users tap the search icon and enter a city name, postal code, or specific address. The app then instantly navigates the map to that exact point, loading the relevant local radar data. This workflow is crucial for monitoring weather conditions for a commute route, a second home, or the location of a loved one. It makes Rainy Days a versatile tool for tracking weather anywhere across its supported global coverage.

Customizable Alert Notifications

Users can configure Rainy Days to send proactive alerts for precipitation events. Within the app's settings, they define their parameters, such as alerting for rain starting within the next 30 minutes or for when snow intensity exceeds a certain level. Once set, the app runs in the background, monitoring the radar data. When the conditions are met, Rainy Days sends a push notification to the user's device. This feature creates a valuable feedback loop, ensuring users are never caught off guard by a sudden change in the weather.

Offline Map Viewing Capability

Understanding that connectivity can be unreliable during severe weather, Rainy Days includes an offline function. Users proactively download the radar data for a specific area while they have an internet connection. Later, if they lose service, they can still access the most recently downloaded map within the Rainy Days app. This provides a critical reference during power outages or in remote areas, allowing for continued weather monitoring based on the last available data.
