Both are free to download. Dogl Precalculus sells 2 one-off in-app purchases and Flocus sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Flocus holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Dogl Precalculus has 17 ratings behind it against 1, so its average is the more settled of the two.
