# Reef Buddy vs NextUpReef

The clearest difference is rating: NextUpReef at 5.0 against Reef Buddy's 4.1. NextUpReef also leads on review sentiment (100% vs 60%) and update cadence (every 4 days vs every 2 weeks). Reef Buddy's advantage is ratings volume (19 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Reef Buddy sells 4 in-app purchases, starting at $0.99 per 7 days and NextUpReef sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
