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
• 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
Free to download and use offline for planning dives up to 30m, no account required. Full planning access — including deeper technical dives — requires signing in and being reviewed as a verified technical diver, mirroring the certification those dives require in practice. This also unlocks cloud sync of your dive plans and settings 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.
