# Partial Calendar vs PDF Reader

The clearest difference is review sentiment: Partial Calendar at 100% against PDF Reader's 50%. Partial Calendar also leads on rating (5.0 vs 4.0) and ads (none vs shown). PDF Reader's advantage is ratings volume (41 vs 4) and chart position (#122 vs unranked). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Partial Calendar sells 2 in-app purchases, starting at $1.99 per month and PDF Reader sells 1 in-app purchase, starting at $14.99 per 7 days. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: PDF Reader has 41 ratings behind it against 4, so its average is the more settled of the two.
