Verdict

The call

The clearest difference is rating: PDF Reader at 4.7 against Chinese Calendar's 2.0. PDF Reader also leads on review sentiment (37% vs 0%) and update cadence (every 8 days vs every 2 months). Chinese Calendar's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
