# Brain Tool Kit vs iHeart Brain

The clearest difference is price: iHeart Brain at Free against Brain Tool Kit's $17.99. iHeart Brain also leads on rating (5.0 vs 4.3) and update cadence (fortnightly vs every 5 weeks). Brain Tool Kit's advantage is in-app purchases (none vs 3) and chart position (#45 vs unranked). On ads and device support there is nothing between them.

iHeart Brain is free to download; Brain Tool Kit costs $17.99 up front. iHeart Brain sells 3 in-app purchases, starting at $1.99 per month. Brain Tool Kit asks for nothing beyond the download.

iHeart Brain holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Brain Tool Kit has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of Brain Tool Kit's written reviews are positive against 75% of iHeart Brain's, so the app with the better star average is not the one people write more warmly about.

Brain Tool Kit ships an update every 5 weeks, iHeart Brain fortnightly. The most recent releases landed on October 14, 2026 and October 4, 2026 respectively.
