A RainDrop author compares the data with his rain gauge. The summary benefits from a source and a period, so that a model estimate is not mixed with a local measurement.
The app is valued for its graphical precipitation accuracy and an honest 14-day horizon without extra noise. The hourly forecast periodically breaks and shows only one time slot, making it a useless widget until the next refresh.
評価点:Accurate precipitation figures without panic or unnecessary dramatization.
不満点:The hourly forecast sometimes collapses to a single 1 a.m. row and stops updating without a reinstall.
向いている人:Those planning trips, outdoor work, or farming tasks two weeks out
An app with a unique niche for tracking rainfall for farmers and agronomists, and when the data matches a physical rain gauge it is irreplaceable. But systematically underreporting actual precipitation by 30-40% compared to physical measurements is the key accuracy problem.
評価点:Historical precipitation data for a specific map point without needing to go check a physical gauge.
不満点:Precipitation data regularly underreports physical gauge readings by a third or more.
向いている人:Farmers and agronomists monitoring plot moisture
Tomorrow.io outperforms most competitors on hyperlocal precipitation forecasts tied to exact map coordinates, but the 10-day forecast is unstable, sunrise/sunset times show an offset, and push notifications regularly fail to fire.
評価点:Precipitation forecast is tied to precise coordinates rather than the city as a whole, which matters most in areas with complex terrain.
不満点:The daily and hourly forecasts sometimes contradict each other, which is confusing when planning.
向いている人:Those for whom it matters whether rain will fall here in the next hour
A clean, ad-free interface layered over NWS data, with a forecast discussion forum. Accuracy is good in spring and summer, slightly weaker in winter. The most honest minimalism in the segment.
評価点:The NWS forecaster Forecast Discussion is the most informative text forecast available, something no other app offers.
不満点:Zone and acronym navigation is opaque for newcomers, and switching regions takes extra steps.
向いている人:US users who want raw NWS data without extra layers
Pleasant visuals and hyperlocal forecast for rural areas where the nearest airport station is far away, but accuracy is inconsistent. Radar maps without a legend are nearly useless, and unit settings reset on their own.
評価点:Hyperlocal forecast is useful in remote areas where the nearest weather station is 30 miles away.
不満点:The radar has no color legend, so it is impossible to read precipitation intensity from the map.
