# Brain X vs NutriSea

The clearest difference is in-app purchases: NutriSea at none against Brain X's 7. NutriSea also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 71%). Brain X's advantage is ratings volume (66 vs 1) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Brain X sells 7 in-app purchases, starting at $6.99 per 7 days. NutriSea asks for nothing beyond the download.

NutriSea holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Brain X has 66 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 71% of Brain X's written reviews are positive against 100% of NutriSea's.

Brain X ships an update every 3 days, NutriSea every 4 days. The most recent releases landed on October 24, 2026 and October 7, 2026 respectively.
