# ReefBay vs ReefMind

The clearest difference is ads: ReefMind at none against ReefBay's shown. ReefBay's advantage is update cadence (weekly vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

ReefBay ships an update weekly, ReefMind every 5 weeks. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
