# Keep vs 三双

The clearest difference is ads: 三双 at none against Keep's shown. Keep's advantage is device support (4 vs 2) and iOS requirement (14.0 vs 16.0). On price and in-app purchases there is nothing between them.

Both are free to download. Keep sells 12 in-app purchases, starting at $2.99 per month and 三双 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
