# PDFOptim vs SuperTuber

The clearest difference is review sentiment: SuperTuber at 100% against PDFOptim's 76%. SuperTuber also leads on rating (5.0 vs 4.7). PDFOptim's advantage is ratings volume (292 vs 4) and iOS requirement (15.6 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDFOptim sells 3 in-app purchases, starting at $0.99 per month and SuperTuber sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
