# Air vs IELTS Reading Test

The clearest difference is monetization model: Air at free against IELTS Reading Test's ad-supported. IELTS Reading Test's advantage is device support and iOS requirement (13.0 vs 18.2). 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.
