# Physarum vs NeuroPhysMatrix

The clearest difference is update cadence: NeuroPhysMatrix at every 2 weeks against Physarum's every 5 weeks. NeuroPhysMatrix also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Physarum sells 3 one-off in-app purchases and NeuroPhysMatrix sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Physarum ships an update every 5 weeks, NeuroPhysMatrix every 2 weeks. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
