VizReport is the satellite-powered water visibility platform built for divers. We deliver daily clarity reports derived from space-based ocean color sensors directly to your phone -- so you always know conditions before you suit up. Whether you're planning a reef dive in the tropics, a wreck dive on the continental shelf, or a freedive in open water, VizReport tells you exactly what to expect underwater. Built by divers, for divers. WHY DIVERS CHOOSE VIZREPORT: Water Visibility Intelligence Stop guessing. VizReport converts satellite-derived Secchi depth measurements into real underwater visibility estimates, updated daily from the Copernicus GlobColour ocean color constellation. View visibility contours overlaid on the chart to find the clearest water near you. Multiple Satellite Data Layers Go beyond visibility. VizReport gives you access to the same professional-grade ocean data used by marine scientists: Sea Surface Temperature (SST): 9 daily scans from GHRSST, MODIS, VIIRS, and AVHRR satellites. Find warm, comfortable water. Chlorophyll Concentration: 6 daily sources to identify plankton blooms that reduce visibility. True Color Imagery: See real ocean conditions -- sediment plumes, algae, and coastal runoff -- before you leave the dock. Ocean Currents: Copernicus global current analysis to plan drift dives and anticipate conditions. Global 3D Bathymetry Explore the underwater landscape before you descend. High-resolution global bathymetry reveals reef structure, walls, drop-offs, and seamounts worldwide. Combine depth data with visibility to choose the perfect dive site. On-Chart Visibility Readout Point anywhere on the chart to see estimated underwater visibility in meters or feet. VizReport converts raw satellite data into a diver-relevant visibility number so you can make informed decisions at a glance. 100% Offline Capability VizReport is built for boat use. The app automatically caches all chart layers, visibility data, and bathymetry as you view them. Browse your dive region on Wi-Fi, then head offshore with full access and zero cell signal. BETTER DATA, BETTER DIVES Global Coverage: Dive anywhere in the world. No regional restrictions. No Hardware: Just your phone. No expensive equipment needed. Daily Updates: Satellite data processed overnight and ready each morning. Visibility Contours: See clarity gradients on the chart to navigate toward clearer water. WHO IS VIZREPORT FOR? Recreational Divers: Check conditions before booking a dive. Find the clearest water in your area. Dive Operators & Guides: Choose sites with the best visibility to keep clients happy. Save fuel by running straight to clear water. Freedivers & Spearfishers: Locate warm, clear water where visibility matters most. Underwater Photographers & Videographers: Plan shoots around optimal clarity windows. Dive Trip Planners: Compare visibility trends across destinations to time your next trip perfectly. THE SCIENCE BEHIND THE CLARITY VizReport processes Secchi disk depth data from the Copernicus Marine Service's GlobColour constellation -- a global, gap-free, satellite-derived measure of water transparency updated daily. We enhance the raw data with coastal dilation to extend coverage to nearshore dive sites, then convert Secchi depth into practical dive visibility estimates. SST, chlorophyll, and true color data come directly from NASA and NOAA satellites (MODIS, VIIRS, AVHRR, PACE, and GHRSST). Download VizReport today. Know the viz before you dive.

DivePlot

Turn your dive computer log into a beautiful photo overlay. DivePlot reads a dive straight from your dive computer over Bluetooth and turns it into a clean, professional overlay: your depth profile as a graph, live readouts like a dive computer, or both — on top of your own dive photo or as a transparent PNG for your video editor. How it works 1. Connect your dive computer and pick one of your latest dives. 2. Style your overlay: graph lines, colors, line thickness, text fields and a legend. 3. Export to your photo album or share it directly. Overlay studio • Depth, temperature, deco, pO₂ and tank pressure as graph lines — each with its own color and toggle • Dive computer mode: replay your dive with live depth, time, pO₂, temperature, CNS and tank pressure readouts • Scrub to any moment of the dive — the readouts follow • Add your own photo as background, with zoom, pan, dim and blur • Effects below the depth line: darken, grayscale or blur • Draggable text fields (depth, duration, date, time, your name) with size, color, alignment and outline • Legend, line thickness slider and multiple export formats: 16:9, 4:3, 9:16, 3:4, 1:1 and 4:5 • Save your favorite designs and reuse them on the next dive • No photo? Export a transparent PNG to use as an overlay in any video editor Supported dive computers DivePlot connects to the Halcyon Symbios (handset and HUD) over Bluetooth and downloads your most recent dives — including rebreather data such as cell pO₂ and tank pressure. Support for more brands is in the works. No account, no ads, no tracking. Your dives stay on your device. Free version adds a small "created with DivePlot app" watermark; a one-time purchase removes it.

Verdict

The call

The clearest difference is update cadence: VizReport at every 5 days against DivePlot's fortnightly. DivePlot's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
