# MEDELETRO vs QR Class

The clearest difference is update cadence: MEDELETRO at every 5 weeks against QR Class's every 4 months. QR Class's advantage is iOS requirement (12.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

MEDELETRO ships an update every 5 weeks, QR Class every 4 months. The most recent releases landed on September 4, 2026 and September 8, 2026 respectively.
