# Mares App vs DiveBuddy

The clearest difference is review sentiment: DiveBuddy at 100% against Mares App's 47%. DiveBuddy also leads on rating (5.0 vs 4.5) and update cadence (daily vs every 3 weeks). Mares App's advantage is ratings volume (183 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mares App sells 8 in-app purchases, starting at $2.99 per month and DiveBuddy sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
