# NetOptimizer vs CosmoVPN

The clearest difference is ads: NetOptimizer at none against CosmoVPN's shown. CosmoVPN's advantage is review sentiment (100% vs 67%) and rating (4.8 vs 4.5). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. NetOptimizer sells 1 in-app purchase, starting at $0.99 per year and CosmoVPN sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

CosmoVPN holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 41 and 82 respectively. Written reviews point the same way: 67% of NetOptimizer's written reviews are positive against 100% of CosmoVPN's.
