Diveplan vs Tech Dive

This app is an aid to your dive planning, enabling you to plan multiple dives using multiple gas mixes - fully supporting air, enriched/nitrox and trimix dives with unlimited cylinders and mixes. This app is only an aid and must not be used in place of proper training and a dive computer. It only provides estimates of gas usage and decompression stops - you should not use this app to make any decisions related to your safety.

Diving should be safe and fun. We develop Tech Dive as a simple tool to plan and calculate your next underwater adventure. Tech Dive is an advanced scuba dive calculator and supports metric and imperial units. This app continues to grow as a one-stop technical diver tool. A technical decompression (DECO) planner will be incorporated with the future PRO version.
