# FocusBrain vs Study852

The clearest difference is monetization model: Study852 at free with in-app purchases against FocusBrain's subscription. Study852 also leads on ads (none vs shown) and rating (5.0 vs 4.8). FocusBrain's advantage is ratings volume (116 vs 2) and iOS requirement (16.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. FocusBrain sells 24 in-app purchases, starting at $2.99 per 7 days and Study852 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Study852 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FocusBrain has 116 ratings behind it against 2, so its average is the more settled of the two.
