# Period & Ovulation Calculator vs Lockify

The clearest difference is ads: Lockify at none against Period & Ovulation Calculator's shown. Period & Ovulation Calculator's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.0). On price and in-app purchases there is nothing between them.

Both are free to download. Period & Ovulation Calculator sells 10 in-app purchases, starting at $1.99 per 7 days and Lockify sells 1 in-app purchase, starting at $29.99 per year. Whichever you choose, the download price is not the number that matters.
