Dive Wise is a scuba dive planner, dive logbook, underwater camera, and site mapper built for divers who want one private toolkit on their phone. Plan dives, log dives fast, color-correct underwater photos and videos, map dive sites, and review your dive history without creating an account. Dive Wise is offline-first: your dive data stays on your device unless you choose to export, back up, or share it. PLAN SAFER DIVES - Build recreational or technical dive plans with NDL, gas, turn pressure, MOD, ppO2, CNS, OTU, and decompression information. - Use Buhlmann ZHL-16C with Gradient Factors or VPM-B with conservatism levels. - Plan multi-gas, multi-level, nitrox, trimix, and CCR dives. - Check range plans, gas blending, altitude settings, repetitive dives, air breaks, tides, and weather. LOG DIVES FASTER - Add a dive in seconds with a customizable quick-entry wizard. - Check in by GPS and prefill site, gear, gas, conditions, buddy, and operator details. - Detect dives automatically with compatible depth sensors. - Sync supported Shearwater computers over Bluetooth and avoid duplicate logs. - Import and export UDDF, JSON, and CSV, with full local backup and restore. CAPTURE BETTER UNDERWATER MEDIA - Use an underwater camera designed for diving, not land. - Auto-detect water type and apply real-time color correction. - Adjust correction by depth, red/magenta filters, strobes, and custom presets. - Use Pro controls such as ISO, shutter, white balance, focus, zoom, histogram, zebras, focus peaking, level, grid, compass, and safe-area overlays where supported. - Keep photos and videos grouped by dive session and linked to the matching dive log. EXPLORE YOUR DIVE HISTORY - View dives on a world map with grouped site markers. - Track stats, personal records, SAC trends, countries, buddies, and milestones. - Search your logbook with 14 filters and save presets. - Auto-group trips by country and date. - Map dive sites with waypoints, routes, depth profiles, hazards, marine life, and offline bathymetry tiles. MANAGE GEAR AND DIVE DATA - Save cylinders, gas mixes, gear templates, exposure suits, weights, and accessories. - Track equipment, certifications, buddies, operators, and maintenance reminders. - Identify and reference marine life with an offline species database. - Choose your units: meters or feet, Celsius or Fahrenheit, bar or psi, kilograms or pounds. Built by divers for divers, Dive Wise is a practical mobile toolkit for planning, logging, filming, mapping, and learning from every dive.

Weights Check helps you calculate buoyancy for your equipment and keep track of your weights and configurations. Enter your gear once, build a configuration from it, and see how it balances at the 3 m stop and at depth. Record your weight checks and the calculator adjusts to what your own rig did. EQUIPMENT LIBRARY Cylinders, suits, wings, backplates, regulators, lights and stages go in once, across seven categories, with figures from a maintained, sourced reference table. Every configuration you build picks from this library, so each new one takes less time than the last. CONFIGURATIONS Build a configuration for each way you dive, with its lead and where the lead sits. Copy one and change one thing: the suit, fresh or salt water, single to doubles or sidemount, a stage added, the lead moved from belt to plate. Everything recalculates, and a mounting brings the hardware it needs with it. On first launch, three questions build a sample configuration to start from. BUOYANCY CALCULATOR Every configuration opens on its balance. At the 3 m stop with 50 bar in every cylinder, one signed figure on a bar from sinks to floats shows how the rig sits, with the range of the estimate. At depth, it shows what it would take to swim up if the wing failed, and whether the wing you fitted has the lift. Under the balance is the same dive item by item: what each piece of equipment is worth at the stop and at depth, the gas in the back cylinders and in every stage, the totals with and without your lead, and one line on what to change. WEIGHT CHECKS Record a check with the lead you finished on, at 3 m with 50 bar in every cylinder, and the calculator adjusts: the range narrows around what your rig actually did. Until then, it estimates your suit from published material figures and your body from your weight, height and sex, and labels the result as an estimate. A tag on every configuration says what its figures stand on: your own check and its date, a check from another rig, or a plan. Every check is kept, newest first, with what you entered. ALSO IN THE APP • Where the lead sits and how much of it is ditchable • A warning above a load you set for yourself • Metric and imperial, switched across the app • A configuration you dived but have not recorded waits at the top of the library • Deleted gear waits in Settings until you clear it • Works offline and syncs through your own iCloud to your other devices and the Diver.Today apps Use the figures to plan your weighting, then finish with your own weight check in the water. Weights Check keeps it and calculates from it.
