# 15그램 vs 글로벌 비서

The clearest difference is ads: 글로벌 비서 at none against 15그램's shown. 15그램's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
