# Flutter vs NeuroCraft

The clearest difference is ads: NeuroCraft at none against Flutter's shown. NeuroCraft also leads on review sentiment (100% vs 73%) and rating (5.0 vs 4.7). Flutter's advantage is ratings volume (4.9K vs 4) and iOS requirement (15.0 vs 18.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flutter sells 10 one-off in-app purchases and NeuroCraft sells 9 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

NeuroCraft holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Flutter has 4.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 73% of Flutter's written reviews are positive against 100% of NeuroCraft's.

Flutter ships an update every 8 days, NeuroCraft weekly. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
