# Concentration Grid vs Brain Training

The clearest difference is price: Brain Training at Free against Concentration Grid's $0.99. Brain Training also leads on rating (4.6 vs 4.3) and ratings volume (92 vs 7). Concentration Grid's advantage is ads (none vs shown) and chart position (#63 vs unranked). On review sentiment, in-app purchases and device support there is nothing between them.

Brain Training is free to download; Concentration Grid costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Brain Training holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Brain Training has 92 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 57% of Concentration Grid's written reviews are positive against 52% of Brain Training's, so the app with the better star average is not the one people write more warmly about.

Concentration Grid ships an update every 4 weeks, Brain Training every 2 months. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
