# X vs BrainBlitz

The clearest difference is in-app purchases: X at none against BrainBlitz's 1. X also leads on iOS requirement (15.6 vs 17.6). BrainBlitz's advantage is update cadence (every 2 days vs every 5 weeks). On price, ads and device support there is nothing between them.

Both are free to download. BrainBlitz sells 1 one-off in-app purchase. X asks for nothing beyond the download.

X ships an update every 5 weeks, BrainBlitz every 2 days. The most recent releases landed on September 28, 2026 and October 1, 2026 respectively.
