# Unzip vs Sound

The clearest difference is in-app purchases: Sound at none against Unzip's 2. Unzip's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.8.3). On price and device support there is nothing between them.

Both are free to download. Unzip sells 2 in-app purchases, starting at $0.99 per month. Sound asks for nothing beyond the download.
