# BrainArk vs 智慧写字

The clearest difference is in-app purchases: 智慧写字 at none against BrainArk's 4. 智慧写字 also leads on update cadence (every 6 days vs every 2 weeks) and iOS requirement (13.0 vs 15.6). On price, ads and device support there is nothing between them.

Both are free to download. BrainArk sells 4 one-off in-app purchases. 智慧写字 asks for nothing beyond the download.

BrainArk ships an update every 2 weeks, 智慧写字 every 6 days. The most recent releases landed on October 16, 2026 and October 10, 2026 respectively.
