Glaucus

The assembly and pre-dive checklist built for KISS Sidewinder divers. Rebreathers don't forgive skipped steps. GLAUCUS walks you through the full build — 23 guided steps from canister packing to positive and negative pressure tests — and records what you actually measured, not what you meant to measure. ASSEMBLY CHECKLIST Guided, phase by phase: O-ring lubrication, sorb, assembly, and tests. Nothing marked complete until it's done. SORB MANAGEMENT Track hours used and time remaining on each scrubber independently. Change one, keep the other — the app follows. SENSOR VERIFICATION Record mV readings in air and in oxygen. GLAUCUS calculates linearity and flags cells drifting out of range, using thresholds you define. PRESSURE TESTS Built-in timers for positive and negative tests, with start and end readings recorded and drift computed. DIVE LOG Log dives manually or import from your dive computer via CSV. Depth profile, gas, set point, and battery in one record. PDF REPORTS Every completed assembly and pre-dive check exports as a PDF you can share with your buddy, your instructor, or your own records. YOU SET THE LIMITS Maximum sorb time. Yellow and red thresholds. Sensor mV ranges. Linearity tolerance. GLAUCUS ships with sensible defaults and lets you change every one of them to match your procedure and your training. WORKS OFFLINE Everything is stored on your device. No signal needed on the boat. Available in English, Portuguese and Spanish. Currently supports the KISS Sidewinder. Additional models in development. FREE All features are available, with no usage limits. IMPORTANT GLAUCUS is a support tool. It does not replace your training, your manufacturer's manual, or your own judgement. A rebreather is life-support equipment — use the app alongside your procedure, never in place of it.
