# DR vs OctetLab

The clearest difference is ads: OctetLab at none against DR's shown. DR's advantage is device support (3 vs 1) and iOS requirement (15.3 vs 26.0). On price and in-app purchases there is nothing between them.

Both are free to download. DR sells 2 in-app purchases, starting at $0.99 per 7 days and OctetLab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
