# Weather Underground vs Sainlogic

The clearest difference is rating: Weather Underground at 3.9 against Sainlogic's 1.6. Weather Underground also leads on ratings volume (32K vs 85) and chart position (#17 vs unranked). Sainlogic's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Weather Underground sells 3 in-app purchases, starting at $3.99 per month. Sainlogic asks for nothing beyond the download.

Weather Underground holds the better App Store score, 3.9 against 1.6.
