# ZeroNAS vs SubnetMaster

The clearest difference is rating: SubnetMaster at 5.0 against ZeroNAS's 1.0. ZeroNAS's advantage is in-app purchases (none vs 3) and ratings volume (5 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. SubnetMaster sells 3 in-app purchases, starting at $4.99 per month. ZeroNAS asks for nothing beyond the download.

SubnetMaster holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: ZeroNAS has 5 ratings behind it against 1, so its average is the more settled of the two.
