# ZT vs RS Drive

The clearest difference is rating: ZT at 4.7 against RS Drive's 2.0. ZT also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (282 vs 6). On price, review sentiment, 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.

ZT holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: ZT has 282 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 19% of ZT's written reviews are positive against 27% of RS Drive's, so the app with the better star average is not the one people write more warmly about.

ZT ships an update every 3 weeks, RS Drive every 4 months. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
