# PPI Calc vs Master Post

The clearest difference is ads: PPI Calc at none against Master Post's shown. PPI Calc also leads on rating (4.4 vs 4.1) and monetization model (free vs ad-supported). Master Post's advantage is review sentiment (100% vs 87%). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PPI Calc holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 70 and 29 respectively. Written reviews complicate that: 87% of PPI Calc's written reviews are positive against 100% of Master Post's, so the app with the better star average is not the one people write more warmly about.
