# Relativistic Space vs phase estimation algorithm

The clearest difference is update cadence: phase estimation algorithm at monthly against Relativistic Space's every 75 months. Relativistic Space's advantage is iOS requirement (13.0 vs 16.0). 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.

Relativistic Space ships an update every 75 months, phase estimation algorithm monthly. The most recent releases landed on October 7, 2026 and October 10, 2026 respectively.
