# phase estimation algorithm vs MARVLS

The clearest difference is iOS requirement: phase estimation algorithm at 16.0 against MARVLS's 18.0. On price, update cadence, 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.

phase estimation algorithm ships an update monthly, MARVLS every 4 weeks. The most recent releases landed on September 15, 2026 and September 9, 2026 respectively.
