# PerfectLine vs R2G

The clearest difference is review sentiment: PerfectLine at 88% against R2G's 20%. PerfectLine also leads on update cadence (every 9 days vs every 5 weeks) and ratings volume (6 vs 1). R2G's advantage is rating (5.0 vs 3.7) and in-app purchases (none vs 20). On price, device support and iOS requirement there is nothing between them.

Both are free to download. PerfectLine sells 20 in-app purchases, starting at $9.90 per month. R2G asks for nothing beyond the download.

R2G holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: PerfectLine has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of PerfectLine's written reviews are positive against 20% of R2G's, so the app with the better star average is not the one people write more warmly about.

PerfectLine ships an update every 9 days, R2G every 5 weeks. Both last shipped on October 21, 2026.
