DiveCast - Dynamic Planner

DiveCast is a dynamic dive planning tool built for technical divers who need accurate, real-time decompression and gas planning — on the boat, at the dive site, or at home. KEY FEATURES • Real-time dive profile planning with live decompression calculations (Bühlmann ZHL-16 with gradient factors) • Full gas planning: bottom, deco, and diluent gas mixes with MOD, density, and no-decompression limits calculated automatically • CNS and OTU oxygen toxicity tracking alongside your deco stop schedule • Gas Library — save and reuse your standard gas configurations, synced across devices when signed in • Stress scenario modeling — instantly rescale SAC and ascent rates for elevated-exertion or emergency conditions • Supports open-circuit, closed-circuit (rebreather), and bailout planning • Consecutive dive planning that carries over tissue loading from your previous dive • Configurable ascent/descent rates, SMB deployment drift, and surface planning parameters • Fully usable offline for planning dives up to 30m, no account required. Full planning access — including deeper technical dives — requires signing in as a verified technical diver, which also unlocks cloud sync across devices DiveCast is built for certified technical divers with training in decompression theory and gas management. It is a planning aid, not a substitute for training, certification, or dive computer verification — always cross-check dive plans against your training and equipment before diving.
