# Proviewer vs OpenHTML

The clearest difference is in-app purchases: Proviewer at none against OpenHTML's 1. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. OpenHTML sells 1 one-off in-app purchase. Proviewer asks for nothing beyond the download.
