# SORARI vs きくPDF

The clearest difference is ads: きくPDF at none against SORARI's shown. きくPDF also leads on update cadence (every 4 days vs every 2 months). SORARI's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 18.0). On price and in-app purchases there is nothing between them.
