# Dive Plan vs Mares App

The clearest difference is rating: Mares App at 4.5 against Dive Plan's 1.8. Mares App also leads on ratings volume (183 vs 8) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Dive Plan sells 4 in-app purchases, starting at $2.99 per month and Mares App sells 8 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Mares App holds the better App Store score, 4.5 against 1.8. That said, the two scores are not equally well evidenced: Mares App has 183 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 38% of Dive Plan's written reviews are positive against 47% of Mares App's.

Dive Plan ships an update every 2 months, Mares App every 3 weeks. The most recent releases landed on September 24, 2026 and September 26, 2026 respectively.
