# Impulse vs BrainFox

The clearest difference is rating: Impulse at 4.7 against BrainFox's 4.0. Impulse also leads on ratings volume (849K vs 40) and review sentiment (69% vs 53%). BrainFox's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Impulse sells 14 in-app purchases, starting at $4.99 per 7 days and BrainFox sells 4 in-app purchases, starting at $9.99 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 4.0. That said, the two scores are not equally well evidenced: Impulse has 849K ratings behind it against 40, so its average is the more settled of the two. Written reviews point the same way: 69% of Impulse's written reviews are positive against 53% of BrainFox's.

Impulse ships an update every 6 days, BrainFox every 9 days. The most recent releases landed on September 25, 2026 and September 6, 2026 respectively.
