# IELTS Writing Test vs Data Science

The clearest difference is ads: Data Science at none against IELTS Writing Test's shown. IELTS Writing Test's advantage is iOS requirement (13.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.

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