# Optics Trainer vs NetraYoga

The clearest difference is ads: NetraYoga at none against Optics Trainer's shown. NetraYoga also leads on iOS requirement (13.0 vs 16.4). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Optics Trainer sells 3 in-app purchases, starting at $4.99 per 7 days and NetraYoga sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
