# OnScene vs MedTerms

The clearest difference is update cadence: MedTerms at every 2 weeks against OnScene's every 6 weeks. OnScene's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. OnScene sells 2 one-off in-app purchases and MedTerms sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OnScene ships an update every 6 weeks, MedTerms every 2 weeks. Both last shipped on October 31, 2026.
