# すてふり vs RAM Guard

The clearest difference is review sentiment: すてふり at 100% against RAM Guard's 50%. RAM Guard's advantage is update cadence (weekly vs every 4 months) and rating (4.3 vs 4.0). On price and in-app purchases there is nothing between them.

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

RAM Guard holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: RAM Guard has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of すてふり's written reviews are positive against 50% of RAM Guard's, so the app with the better star average is not the one people write more warmly about.

すてふり ships an update every 4 months, RAM Guard weekly. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
