# Slotter vs Memory Stamps

The clearest difference is rating: Memory Stamps at 4.3 against Slotter's 3.0. Memory Stamps also leads on update cadence (fortnightly vs every 5 months) and ratings volume (82 vs 2). Slotter's advantage is review sentiment (74% vs 40%) and price ($0.99 vs $1.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

Slotter costs $0.99 and Memory Stamps $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Memory Stamps holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Memory Stamps has 82 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of Slotter's written reviews are positive against 40% of Memory Stamps's, so the app with the better star average is not the one people write more warmly about.
