# PocketMDS vs Quantum

The clearest difference is in-app purchases: PocketMDS at none against Quantum's 6. PocketMDS also leads on iOS requirement (12.0 vs 26.0). Quantum's advantage is ratings volume (150 vs 1) and update cadence (every 5 weeks vs every 4 months). On price, rating, ads and device support there is nothing between them.

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

PocketMDS holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Quantum has 150 ratings behind it against 1, so its average is the more settled of the two.

PocketMDS ships an update every 4 months, Quantum every 5 weeks. The most recent releases landed on October 13, 2026 and October 24, 2026 respectively.
