# RFC View vs The Sky by Redshift

The Sky by Redshift also leads on update cadence (every 2 months vs every 13 months) and ratings volume (811 vs 1). RFC View's advantage is in-app purchases (none vs 2) and review sentiment (100% vs 69%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. The Sky by Redshift sells 2 in-app purchases, starting at $0.99 per month. RFC View asks for nothing beyond the download.

The Sky by Redshift holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: The Sky by Redshift has 811 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of RFC View's written reviews are positive against 69% of The Sky by Redshift's, so the app with the better star average is not the one people write more warmly about.

RFC View ships an update every 13 months, The Sky by Redshift every 2 months. The most recent releases landed on June 25, 2026 and September 21, 2026 respectively.
