DiveReady
Read full descriptionHide full description
Stop guessing your weight belt. DiveReady calculates the ballast weight you actually need, based on your body, your exposure suit, your tank setup and whether you're diving fresh or salt water. Enter your weight manually or sync it from Apple Health and DiveReady handles the math every time your setup changes. Before you get in the water, DiveReady also pulls real tide, current and weather data for your dive location and rates conditions against your experience level, so a "moderate" reading means something different for a beginner than it does for a dive pro. What's in the box: - Ballast weight calculated based on the required parameters - Real tide, current and weather conditions for your dive site (only US and US-territory coastal waters for now, more coming soon...) - Condition ratings tuned to your experience level, from beginner to expert - Apple Watch support, so your numbers are on your wrist, not just your phone What DiveReady does not do: No account, no login, no ads. Your body weight never leaves your device. Location and usage data are never sold or used for advertising and analytics can be turned off entirely in Settings. DiveReady is for anyone who's tired of eyeballing a weight belt or trying to remember what worked last trip. Set it up once, adjust it as your gear changes and get a number you can actually trust.
