The clearest difference is update cadence: AlerWX at weekly against Storma's monthly. AlerWX also leads on ratings volume (134 vs 12) and iOS requirement (16.1 vs 26.0). Storma's advantage is review sentiment (100% vs 81%) and device support (4 vs 2). On price, rating, ads and in-app purchases there is nothing between them.
