# week vs One Task

The clearest difference is ads: One Task at none against week's shown. week's advantage is update cadence (every 11 days vs every 4 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. week sells 2 in-app purchases, starting at $1.99 per month and One Task sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
