# PDF Expert vs Citapp Dr

The clearest difference is in-app purchases: Citapp Dr at none against PDF Expert's 12. PDF Expert's advantage is ads (none vs shown) and chart position (#76 vs unranked). On price, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month. Citapp Dr asks for nothing beyond the download.
