# Brain vs No Ads

The clearest difference is in-app purchases: Brain at none against No Ads's 4. Brain also leads on update cadence (every 2 days vs every 10 days) and iOS requirement (15.1 vs 18.0). On price, ads and device support there is nothing between them.

Both are free to download. No Ads sells 4 in-app purchases, starting at $0.99 per month. Brain asks for nothing beyond the download.

Brain ships an update every 2 days, No Ads every 10 days. The most recent releases landed on October 25, 2026 and October 31, 2026 respectively.
