Verdict

The call

The clearest difference is rating: Mares App at 4.5 against Dive Check's 1.0. Mares App also leads on ratings volume (189 vs 2). Dive Check's advantage is update cadence (every 4 days vs every 4 weeks) and iOS requirement (8.0 vs 16.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Dive Check sells 1 one-off in-app purchase 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.

ReceptionRating · Positive reviews · Number of ratings

Mares App holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Mares App has 189 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Dive Check's written reviews are positive against 48% of Mares App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dive Check ships an update every 4 days, Mares App every 4 weeks. The most recent releases landed on September 27, 2026 and October 18, 2026 respectively.
