# aspect vs PPI Calc

The clearest difference is rating: PPI Calc at 4.4 against aspect's 3.3. PPI Calc also leads on review sentiment (87% vs 60%) and ratings volume (70 vs 6). On price, ads, in-app purchases and monetization model 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 3.3. That said, the two scores are not equally well evidenced: PPI Calc has 70 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 60% of aspect's written reviews are positive against 87% of PPI Calc's.
