# BrainFox vs Locked In

The clearest difference is rating: Locked In at 5.0 against BrainFox's 4.0. Locked In also leads on ads (none vs shown). BrainFox's advantage is ratings volume (40 vs 1) and iOS requirement (13.0 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. BrainFox sells 4 in-app purchases, starting at $9.99 per 7 days and Locked In sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Locked In holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: BrainFox has 40 ratings behind it against 1, so its average is the more settled of the two.

BrainFox ships an update every 9 days, Locked In every 2 weeks. The most recent releases landed on October 8, 2026 and October 13, 2026 respectively.
