# RX vs DocOrbit

The clearest difference is in-app purchases: RX at none against DocOrbit's 7. RX also leads on ratings volume (70 vs 7) and iOS requirement (13.0 vs 15.0). DocOrbit's advantage is ads (none vs shown) and update cadence (daily vs every 6 months). On price, monetization model and device support there is nothing between them.

Both are free to download. DocOrbit sells 7 one-off in-app purchases. RX asks for nothing beyond the download.

DocOrbit holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: RX has 70 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 90% of RX's written reviews are positive against 100% of DocOrbit's.

RX ships an update every 6 months, DocOrbit daily. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
