Decompression Stop Calculator: Based on the depth and dive time, the app simulates the behavior of a dive computer, providing the user with the necessary information to know how long they can stay at a given depth without making decompression stops. Equipment Checklist: The app includes a complete checklist with all the essential gear for a safe dive. From the regulator to the wetsuit, users can ensure they don't forget any equipment before getting into the water. The design of the Diving Calculator is visually appealing, using blue tones that evoke the underwater environment.
