# Brain Tutor 3D vs DSM

The clearest difference is review sentiment: Brain Tutor 3D at 83% against DSM's 33%. DSM's advantage is update cadence (every 4 months vs every 71 months) and ratings volume (308 vs 11). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brain Tutor 3D sells 3 one-off in-app purchases and DSM sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

DSM holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: DSM has 308 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 83% of Brain Tutor 3D's written reviews are positive against 33% of DSM's, so the app with the better star average is not the one people write more warmly about.

Brain Tutor 3D ships an update every 71 months, DSM every 4 months. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
