Safety Boundaries: What DiveOne Is and Isn't

DiveOne is a recreational dive logging and tracking tool. It records depth to 6 m, time, and temperature using Apple Watch hardware sensors. It creates a dive journal automatically, exports a CSV summary and a JSON backup, and records dives offline before moving them to iPhone after surfacing.

DiveOne is not a dive computer. It does not calculate decompression limits, no-decompression times, or ascent rates for safety purposes. It does not replace your BCD, regulator, backup air source, or any piece of life-support equipment. It does not provide gas mix analysis, O2 toxicity warnings, or nitrogen loading estimates.

Your primary safety equipment is: certified dive computer, BCD, regulator, backup air source, and your training. DiveOne sits in the secondary category: a logging companion that records your dive alongside your primary gear. Think of it as a dive journal that writes itself — not as safety equipment.

DiveOne is not a dive computer, and we do not market it as one. We do not claim certifications we do not have. We do not interpolate or invent sensor data: if a reading is invalid, we mark it as unavailable. Your safety depends on honest tools, and we take that seriously.
