# Brain Test vs All You Can ET

The clearest difference is rating: All You Can ET at 4.8 against Brain Test's 4.1. All You Can ET also leads on in-app purchases (none vs 2) and ads (none vs shown). Brain Test's advantage is update cadence (every 2 weeks vs every 39 months) and ratings volume (71 vs 10). On price, review sentiment and device support there is nothing between them.

Both are free to download. Brain Test sells 2 one-off in-app purchases. All You Can ET asks for nothing beyond the download.

All You Can ET holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Brain Test has 71 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 72% of Brain Test's written reviews are positive against 67% of All You Can ET's, so the app with the better star average is not the one people write more warmly about.

Brain Test ships an update every 2 weeks, All You Can ET every 39 months. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
