# Calculation Training For Brain vs Impulse

The clearest difference is update cadence: Impulse at every 6 days against Calculation Training For Brain's every 5 months. Impulse also leads on ratings volume (849K vs 14) and rating (4.7 vs 4.4). Calculation Training For Brain's advantage is review sentiment (86% vs 69%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculation Training For Brain sells 1 one-off in-app purchase and Impulse sells 14 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Impulse holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Impulse has 849K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 86% of Calculation Training For Brain's written reviews are positive against 69% of Impulse's, so the app with the better star average is not the one people write more warmly about.

Calculation Training For Brain ships an update every 5 months, Impulse every 6 days. The most recent releases landed on August 4, 2026 and September 25, 2026 respectively.
