# DynaMed vs PsychAtlas

The clearest difference is update cadence: DynaMed at every 5 weeks against PsychAtlas's every 17 months. DynaMed also leads on ratings volume (3.5K vs 1) and iOS requirement (18.4 vs 26.5). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.9 for DynaMed against 5.0 for PsychAtlas. That said, the two scores are not equally well evidenced: DynaMed has 3.5K ratings behind it against 1, so its average is the more settled of the two.

DynaMed ships an update every 5 weeks, PsychAtlas every 17 months. Both last shipped on September 28, 2026.
