# Brain Challenge vs Unblock

The clearest difference is review sentiment: Brain Challenge at 75% against Unblock's 0%. Brain Challenge also leads on in-app purchases (none vs 5) and ads (none vs shown). Unblock's advantage is rating (5.0 vs 4.4). On price, monetization model and device support there is nothing between them.

Both are free to download. Unblock sells 5 in-app purchases, starting at $4.99 per 7 days. Brain Challenge asks for nothing beyond the download.

Unblock holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Brain Challenge has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Brain Challenge's written reviews are positive against 0% of Unblock's, so the app with the better star average is not the one people write more warmly about.

Brain Challenge ships an update every 2 months, Unblock every 61 months. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
