# Calculator vs AI文案助手

The clearest difference is in-app purchases: AI文案助手 at none against Calculator's 2. Calculator's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.1). On price and device support there is nothing between them.

Both are free to download. Calculator sells 2 one-off in-app purchases. AI文案助手 asks for nothing beyond the download.
