Nail your weighting every dive. Enter your body weight, exposure suit, tank, and water type — get instant lead weight recommendations. Quickly find out the suggested weight you should add when scuba diving in different environments. Based on PADI's Peak Performance Buoyancy basic weighting guideline*. Enter your weight in pounds or kilograms, and additionally set the type of water, tank, and exposure suit to dial in a suggested amount of weight to help keep you neutrally buoyant. *Note that this app and the developer are not officially a representative of PADI. This app will give the user a good estimate of the weight needed for the environment selected, but there are always adjustments needed to achieve peak performance, based on gender, physique, exposure suit age, accessories, etc.

Not bad as it will get you somewhere near your required weight. I’ve used this as a weight estimator for my students and it always overweights them sometimes by a significant amount. Once you get used to it you’ll start to come up with a fudge factor that works for you. Once you know what your fudge factor is properly weighting yourself when changing tanks, exposure suits and environment becomes a snap.

The best buoyancy calculator!

This is hands down the best buoyancy calculator app on the market. I should know, I’ve used them all. I consider myself a seasoned diver, having dove with all the greats. Pete Lecrerc, Sunny Drinkwater, you name em. But for some reason I can never seem to sink as well as them. This app has changed everything. I am basically a well calculated rock, it’s the best. Jokes aside, this is a solid app, you should download it.

no money take the L lolol
Of course I see everything that says it over weighs, this is just a suggestion that I would like. The ability to not include the tank in the calculations for free diving because 7mm suits can be quite buoyant and may they need some weighing down, it may also be helpful for snorkeling

Great app for on the fly calculations. Developer please check the salt water / dive skin suit calculations as no matter how much weight you put in, it always gives you the same calculate result of 2 pounds.

This update brings a completely refreshed look and feel to Buoyancy Calculator. The interface has been redesigned with a deep ocean-inspired dark theme — rich navy backgrounds, teal accents, and high-contrast text that's easy to read in bright sunlight or a dimly lit dive shop. The results panel at the bottom of the screen has been given more visual prominence, making your lead weight recommendation impossible to miss at a glance. Unit and water type selectors now use a styled segmented control with clear active/inactive states, and the exposure suit and tank pickers render with crisp, readable text throughout. Under the hood, the iOS deployment target has been updated to 15.6, ensuring compatibility with current devices and the latest system frameworks.
