# RAS Mobile I vs DS cam

The clearest difference is rating: DS cam at 3.0 against RAS Mobile I's 1.0. DS cam also leads on ratings volume (177 vs 4). RAS Mobile I's advantage is review sentiment (53% vs 32%) and iOS requirement (9.0 vs 15.0). On price, update cadence, ads 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.

DS cam holds the better App Store score, 3.0 against 1.0. That said, the two scores are not equally well evidenced: DS cam has 177 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 53% of RAS Mobile I's written reviews are positive against 32% of DS cam's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
