# RS vs PTT4U

The clearest difference is rating: PTT4U at 4.0 against RS's 1.9. PTT4U also leads on iOS requirement (8.0 vs 16.0). RS's advantage is ratings volume (76 vs 4) and review sentiment (15% vs 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.

PTT4U holds the better App Store score, 4.0 against 1.9. That said, the two scores are not equally well evidenced: RS has 76 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 15% of RS's written reviews are positive against 0% of PTT4U's, so the app with the better star average is not the one people write more warmly about.

RS ships an update every 8 months, PTT4U every 6 months. Both last shipped on November 2, 2026.
