Storm Tracker°

Storm Tracker° by Impala Studios has been around since late 2014 and carries genuine credibility with 82K ratings averaging 4.63 and 1.4 million downloads worldwide. It bundles Doppler radar, NOAA warnings, and up to 10-day hourly forecasts into a free package. The 304 MB footprint is on the heavier side for a weather utility, but the HD map quality and unlimited location support give it practical everyday reach beyond just storm season.

What It Does Well

The core value here is the 24/7 NOAA alert layer, which plots flood, tide, and storm warnings directly on the map rather than burying them in a notification list. Pairing that with Doppler rain and snow radar gives users a genuine at-a-glance picture of incoming conditions. The 10-day hourly breakdown for temperature, precipitation, wind speed, and pressure is more granular than most free competitors bother to offer, which matters when you are trying to decide whether a weather window is safe.

Where It Falls Short

The NOAA warning layer is explicitly US-only, so international users lose a significant chunk of the advertised functionality. At 304 MB the app is nearly twice the size of comparable weather tools, which raises questions about what is driving that bulk. The app is free but lists in-app purchases without specifying what sits behind the paywall, meaning some features visible in screenshots may require spending before you discover that limitation during an actual storm event.

Who Should Download It

Storm Tracker° makes the most sense for users in the continental United States who live in tornado corridors, hurricane-prone coastal areas, or flood plains and want a single screen that combines radar movement with official government alerts. Casual users checking daily forecasts may find the app heavier than necessary. Its long update history, most recently March 2026, suggests Impala Studios is actively maintaining it, which counts for something in a category where abandoned apps are common.
