# BrainOpen vs 如梦AI

The clearest difference is update cadence: 如梦AI at every 5 weeks against BrainOpen's every 18 months. BrainOpen's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BrainOpen sells 1 in-app purchase, starting at $3.99 per month and 如梦AI sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

BrainOpen ships an update every 18 months, 如梦AI every 5 weeks. The most recent releases landed on September 14, 2026 and May 30, 2026 respectively.
