# Pillow vs Primal Instinct

The clearest difference is rating: Primal Instinct at 5.0 against Pillow's 4.4. Primal Instinct also leads on in-app purchases (none vs 6) and iOS requirement (11.0.0 vs 17.0). Pillow's advantage is ratings volume (96K vs 1) and chart position (#156 vs unranked). On price there is nothing between them.

Both are free to download. Pillow sells 6 in-app purchases, starting at $19.99 per month. Primal Instinct asks for nothing beyond the download.
