What’s new
Version 1.4 · Updated March 3, 2026
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.
