Stop guessing. Start diving. DiveSlate takes the guesswork out of dive planning. We pull together tides, waves, wind, weather, visibility, and currents into a single dive-ability score — updated throughout the day — so you can tell at a glance whether conditions are worth the trip. DIVE-ABILITY SCORE Our 6-factor algorithm combines wave height, wind speed, tidal flow, water visibility, weather conditions, and current strength into one easy-to-read score from 0 to 100. Green means go. Red means maybe hit the pub instead. CURRENT CONDITIONS See up-to-date data for every dive site: water temperature, wave height and period, wind speed and direction, tide stage, and recent visibility reports from fellow divers. HOURLY FORECASTS DiveSlate delivers hour-by-hour condition breakdowns for the current day. Upgrade to Pro for the full 7-day outlook so you can plan your week with confidence. BEST DIVE WINDOW No time to study charts? We highlight the single best window each day — the hour range when conditions peak — so you can plan around your schedule. INTERACTIVE MAP Browse 50+ dive sites across Florida on a beautiful map. Tap any pin to see current conditions, forecasts, and community reports. Filter by dive-ability score to find sites worth visiting right now. COMMUNITY CONDITION REPORTS After your dive, share a quick condition report — visibility, current, surface conditions — and help the entire community dive smarter. Reports feed back into our scoring model to improve accuracy over time. SMART ALERTS Set alerts for your favorite sites. DiveSlate notifies you when conditions hit your target score so you never miss a great dive day. 50+ DIVE SITES From the springs of North Florida to the reefs of the Keys, DiveSlate covers the sites you actually dive.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 5, 2026 respectively.
