# Converter Pro vs Sizer

The clearest difference is in-app purchases: Sizer at none against Converter Pro's 1. Converter Pro's advantage is device support and iOS requirement (18.0 vs 26.0). On price there is nothing between them.

Both are free to download. Converter Pro sells 1 one-off in-app purchase. Sizer asks for nothing beyond the download.
