# MedCalX vs PCR

The clearest difference is rating: PCR at 5.0 against MedCalX's 3.8. PCR also leads on in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 5 months). MedCalX's advantage is ratings volume (31 vs 3). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. MedCalX sells 3 one-off in-app purchases. PCR asks for nothing beyond the download.

PCR holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: MedCalX has 31 ratings behind it against 3, so its average is the more settled of the two.

MedCalX ships an update every 5 months, PCR every 2 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
