# TUS Library vs A

The clearest difference is in-app purchases: TUS Library at none against A's 1. TUS Library also leads on ads (none vs shown) and iOS requirement (11.0 vs 18.0). On price and device support there is nothing between them.

Both are free to download. A sells 1 one-off in-app purchase. TUS Library asks for nothing beyond the download.
