# DiveGenius vs DiveSlate

The clearest difference is review sentiment: DiveGenius at 50% against DiveSlate's 0%. DiveGenius also leads on update cadence (weekly vs every 3 weeks). DiveSlate's advantage is rating (4.0 vs 3.5) and iOS requirement (15.0 vs 26.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. DiveGenius sells 5 in-app purchases, starting at $4.99 per 7 days and DiveSlate sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

DiveSlate holds the better App Store score, 4.0 against 3.5. Both are backed by a comparable volume of ratings — 4 and 2 respectively. Written reviews complicate that: 50% of DiveGenius's written reviews are positive against 0% of DiveSlate's, so the app with the better star average is not the one people write more warmly about.

DiveGenius ships an update weekly, DiveSlate every 3 weeks. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
