# Brain Test vs CrushStations

The clearest difference is in-app purchases: CrushStations at none against Brain Test's 2. CrushStations also leads on ads (none vs shown) and rating (4.5 vs 4.1). Brain Test's advantage is update cadence (every 2 weeks vs every 13 months) and review sentiment (72% vs 50%). On price and device support there is nothing between them.

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

CrushStations holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Brain Test has 71 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 72% of Brain Test's written reviews are positive against 50% of CrushStations'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, CrushStations every 13 months. The most recent releases landed on October 12, 2026 and October 6, 2026 respectively.
