# Lunar Flow Cycle vs s.a.d.e

The clearest difference is update cadence: s.a.d.e at every 5 days against Lunar Flow Cycle's every 2 months. Lunar Flow Cycle's advantage is iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Lunar Flow Cycle sells 2 in-app purchases, starting at $9.99 per month and s.a.d.e sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Lunar Flow Cycle ships an update every 2 months, s.a.d.e every 5 days. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
